Product Number: PA-CT3/4T1(=)
This configuration note describes the installation and configuration of the channelized T3 dual-wide port adapter (PA-CT3/4T1), which can be used in Cisco 7200 series routers.
This configuration note also contains basic configuration steps and examples. For complete descriptions of additional interface subcommands and configuration options available for your router, refer to the appropriate configuration publications listed in the section "If You Need More Information". (Also refer to the section "Software and Hardware Requirements".)
Sections in this document include the following:
The Cisco IOS software running your router contains extensive features and functionality. The effective use of many PA-CT3/4T1 port adapter features is easier if you have more information at hand. For additional information on configuring the Cisco 7200 series routers and the PA-CT3/4T1 port adapter, the following documentation resources are available:
The CT3 channelized port adapter (PA-CT3/4T1) is a dual-wide module that provides four T1 connections via DB-15 connectors and one DS3 connection via BNC connectors. (See Figure 1.) Each DS3 interface can provide up to 28 T1 channels (a single T3 group). Each channel is presented to the system as a serial interface that can be configured individually.
The PA-CT3/4T1 port adapter has the following features and physical characteristics:
T3 traditionally involves multiplexing 28 T1 lines on to a single higher-speed line (T3 line). Each of the 28 T1 lines in the T3 are asynchronous to one other. A T1 line accommodates 24 64-kilobit-per-second (Kbps) DS0 channels. While the DS0s are byte multiplexed to each T1, the T1 lines are bit multiplexed to the T3 in a framing format called M23 or C-BIT parity.
M13 multiplexing is done in two steps. First, four T1 lines are bit multiplexed together to form a DS2 line using M12 multiplexing. These seven DS2 lines are then bit multiplexed together to form the DS3/T3 using M23 multiplexing.
M13 multiplexing uses bit stuffing to bring each asynchronous DS1/DS2 up to a common data rate for transmission. C-BIT Parity multiplexing forces the seven DS2s to be synchronous to each other at a rate that causes 100-percent pulse stuffing in the M23 frame. This allows the "stuff" indicator bits in the M23 frame to be used as a maintenance link between the end points.
The CT3 channelized dual-wide port adapter (PA-CT3/4T1) functions very much like an M13 multiplexer with each T1 line terminating with or originating into or from an HDLC controller on the port adapter. The PA-CT3/4T1 port adapter offers 28 individual T1 channels (bundled in the T3) for serial transmission of data. Each of the T1 channels uses a portion of the T1 bandwidth (fractional T1) or the entire T1 bandwidth for data transmission. Usable bandwidths for each T1 are n x 56 Kbps or n x 64 Kbps, where n is a number from 1 to 24. The unused portion of the T1 bandwidth, when not running at full T1 speeds, cannot be used and is filled with idle channel data.
The T3 section of the PA-CT3/4T1 port adapter supports the maintenance data link channel (C-BIT parity) as well as payload and network loopbacks. The T1 section of the PA-CT3/4T1 port adapter supports facilities data link (FDL) in extended super frame (ESF) framing, as well as network and payload loopbacks. Bit error rate testing (BERT) is supported on each of the T1 links. The BERT testing is only done over a framed T1 signal. The M13 multiplexer performs M12 multiplexing on 4 four T1 signals. (There are seven M12 multiplexers available on board.) The seven M12 multiplexers pass their data to the M23 multiplexer, which takes the seven tributaries and formats them into a DS3 stream. This transmit stream is passed on to the T3 line interface unit (LIU) for transmission out of the BNC connector into a 75-ohm coaxial line.
The first three T1 channels of the channelized T3 can be broken out, under software control, to the three DB-15 connectors on the front of the PA-CT3/4T1 port adapter for further demultiplexing via a MultiChannel Interface Processor (MIP). This allows three (the first three) of the 28 T1 streams in the channelized T3 to be a channelized T1 stream.
The broken-out T1(s) are sent to a T1 LIU, which transmits the T1(s) at the DSX-1 level. (DSX-1 refers to the cross connection point for DS-1 signals.) When operating in this mode, these ports are not CSU ports. They do not detect loop codes, provide ones-density requirements, or respond to any FDL messages. The receiving end (MIP) must provide the CSU functionality. Under software control, each external T1 port can be disabled or enabled.
The PA-CT3/4T1 port adapter does not support the aggregation of multiple T1s (called inverse muxing or bonding) for higher bandwidth data rates. The PA-CT3/4T1 port adapter supports Cisco HDLC, Frame Relay, PPP, and SMDS Data Exchange Interface (DXI) encapsulations over each T1 link. For SMDS only, DXI is sent on the T1 line so it needs to connect to an SMDS switch that has direct DXI input.
There is a special DB-15 connector on the PA-CT3/4T1 port adapter, labeled TEST. This test connector allows you to break out any T1 of the T3 stream, under software control. This functionality allows you to break out any of the 28 T1s within the T3 stream for testing (for example, 24-hour BERT testing as is commonly done by telephone companies before a line is brought into service), or for further channelization via a MIP card.
Figure 2 shows a Cisco 7206 router with port adapters installed. In the Cisco 7206 router, port adapter slot 1 is in the lower left position, and port adapter slot 2 is in the lower right position. (The CT3 channelized port adapter can be installed in any horizontal pair of these slots; use the odd-numbered slot number associated with the left-side slots.)
For T1, two standard serial cables, null-modem and straight-through, are available from Cisco Systems and other vendors for use with the PA-CT3/4T1 port adapter. The PA-CT3/4T1 port adapter T1 interface cables are used to connect your router to external CSUs or a MIP card. The PA-CT3/4T1 port adapter T1 interface cables have two male 15-pin DB connectors at each end to connect the PA-CT3/4T1 port adapter's T1 interfaces.
Figure 3 shows the PA-CT3/4T1 port adapter interface cable, connectors, and pinouts. Table 1 lists the signal pinout for the straight-through cable. Table 2 lists the signal pinout for the null-modem cable.

Follow these basic guidelines when working with any electrical equipment:
Use the following guidelines when working with any equipment that is connected to telephone wiring or to other network cabling:
Electrostatic discharge (ESD) damage, which can occur when electronic cards or components are improperly handled, results in complete or intermittent failures. Port adapters and processor modules consist of printed circuit boards that are fixed in metal carriers. Electromagnetic interference (EMI) shielding and connectors are integral components of the carrier. Although the metal carrier helps to protect the board from ESD, use a preventive antistatic strap during handling.
Use these guidelines to prevent ESD damage:
| Caution For safety, periodically check the resistance value of the antistatic strap. The measurement should be between 1 and 10 megohms. |
This section describes mechanical functions of system components, emphasizes the importance of following correct procedures to avoid unnecessary board failures, and is for background only; specific procedures follow in the section "Installing or Removing a Port Adapter in a Cisco 7200 Series Router".
You can remove and replace port adapters while the system is operating; you do not need to notify the software or reset the system power. This functionality enables you to add, remove, or replace port adapters with the system online, which provides a method that is seamless to end users on the network, maintains all routing information, and ensures session preservation.
After a port adapter is reinstalled, the system brings on line only interfaces that match the current configuration and were previously configured as up; all others require that you configure them with the configure command. .
| Caution The system can indicate a hardware failure if you do not follow proper procedures. Remove or insert only one port adapter at a time. Allow at least 15 seconds for the system to complete the preceding tasks before removing or inserting another port adapter. Disrupting the sequence before the system completes its verification can cause the system to interpret hardware failures. |
All port adapters have ejector levers that allow you to firmly seat a port adapter in the port adapter slot. The function of the ejector levers is to align and seat the card connectors in the backplane. Failure to use the ejector levers and insert the port adapter properly can disrupt the order in which the pins make contact with the backplane.
It is also important to use the ejector levers when removing a port adapter to ensure that the board connector pins disconnect from the backplane in the logical sequence expected by the system. Any port adapter that is only partially connected to the backplane can hang the bus. Detailed steps for correctly installing and removing the port adapter follow.
For detailed directions about removal and installation, follow the procedures in the section "Installing or Removing a Port Adapter in a Cisco 7200 Series Router"..
| Caution Always use the ejector levers to remove or install the PA-CT3/4T1 port adapter. The ejectors help ensure that backplane connectors on the card are fully seated in, or fully ejected from, the backplane. Failure to use the ejector levers could result in a partial backplane connection, which can hang the system. |
The PA-CT3/4T1 port adapter can be installed in any available, horizontally aligned pair of port adapter slots in a Cisco 7200 series router. Figure 4 shows a PA-CT3/4T1 port adapter installed in port adapter slot 3 and slot 4 of a Cisco 7206 router.
You might need to install a new port adapter in a Cisco 7200 series router or replace a failed port adapter in the field. In either case, no tools are necessary; any port adapter available for the Cisco 7200 series routers connects directly to the router midplane and is locked into position by a port adapter lever. When removing and replacing a port adapter, you need the following:
If you plan to remove a PA-CT3/4T1 port adapter or some other dual-wide port adapter from a Cisco 7200 series router and replace it with a PA-CT3/4T1 port adapter, use the instructions in these two sections:
If, however, you are replacing two single-width port adapters (or port adapter blanks) in a Cisco 7200 series router with a new PA-CT3/4T1 port adapter, you first need to remove the port adapter slot divider before you can install the PA-CT3/4T1 port adapter. To do so, use the instructions in these sections:
When a port adapter slot is not in use, a blank port adapter must fill the empty slot. This allows the router to conform to EMI emissions requirements and helps provide proper air flow across the port adapters. If you plan to install a new port adapter in a slot that is not in use, you must first remove a blank port adapter.
The PA-CT3/4T1 port adapter requires two adjacent port adapter slots in a Cisco 7200 series router.
Here is the procedure for removing a port adapter from a Cisco 7200 series router:
Step 1 Attach an ESD-preventive wrist strap to yourself and to an unfinished chassis surface.
Step 2 Move the port adapter lever for the desired port adapter slot to the unlocked position. (See Figure 5.)
Step 3 Grasp the two handles on the port adapter and pull the port adapter from the midplane, about halfway out of its slot. If you are removing a blank port adapter, pull the blank port adapter out of the chassis slot.
Step 4 With the port adapter halfway out of the slot, disconnect all cables from the port adapter.
Step 5 After disconnecting the cables, pull the port adapter from its chassis slot..
| Caution Always handle the port adapter by the carrier edges and handles; never touch the port adapter's components or connector pins. (See Figure 6.) |
Step 6 Place the port adapter on an antistatic surface with its components facing upward, or in a static shielding bag. If you are returning the port adapter to Cisco, immediately place it in a static shielding bag.
The following sections explain how to remove and replace a port adapter slot divider in a Cisco 7200 series router. If you are replacing a PA-CT3/4T1 port adapter, this slot divider is already removed and you can proceed to the section "Installing a Dual-Wide Port Adapter".
Following is the procedure for removing a port adapter slot divider from a Cisco 7200 series router:
Step 1 Remove the port adapters from the slots on both sides of the port adapter slot divider. Refer to the previous section "Removing a Port Adapter" when removing a port adapter from a Cisco 7200 series router.
Step 2 With one hand, raise the slot divider lever to unlock the slot divider from the chassis. (See Figure 7.)
Step 3 With the slot divider lever still raised, use your other hand to pull the slot divider from the chassis. (See Figure 8.)
Step 4 Store the slot divider for use at a later date.
This completes the procedure for removing a port adapter slot divider from a Cisco 7200 series router. Proceed to the section "Installing a Dual-Wide Port Adapter".
Following is the procedure for installing a port adapter slot divider in a Cisco 7200 series router.
Step 1 Position the slot divider so that the slot divider lever faces you and is at the bottom.
Step 2 Align the left and right edges of the slot divider between the guides in the port adapter slot. (See Figure 9.)
Step 3 With the left and right edges of the slot divider aligned in the slot guides, slide the slot divider all the way into the slot until you feel the slot divider lock into place (listen for a click).
This completes the procedure for installing a port adapter slot divider in a Cisco 7200 series router.
Following is the procedure for installing a new dual-wide port adapter in a Cisco 7200 series router:
Step 1 Attach an ESD-preventive wrist strap to yourself and to an unfinished chassis surface.
Step 2 Use both hands to grasp the port adapter by its metal carrier edges with the adapter components facing downward. (See Figure 6.)
Step 3 Align the left and right edges of the port adapter metal carrier between the guides in the port adapter slot. (See Figure 10.)
Step 4 With the metal carrier edges aligned in the slot guides, gently slide the port adapter halfway into the slot..
| Caution Do not slide the port adapter all the way into the slot until you have connected all cables. Doing so disrupts normal operation of the router. |
Step 5 With the port adapter halfway into the slot, connect all required cables to the port adapter.
Step 6 After connecting all required port adapter cables, carefully slide the port adapter all the way into the slot until you feel the port adapter's connectors mate with the midplane.
Step 7 After feeling the connectors mate, move the port adapter lever to the locked position. Figure 11 shows the port adapter lever in the locked position.
This completes the procedure for installing a new port adapter in a Cisco 7200 series router.
Attach the PA-CT3/4T1 port adapter network interface cables between the port adapter interface ports and the CSU. This includes up to four T1 cables and two DS1 BNC cables. (See Figure 12.) Proceed to the following section to check the cable connections.
The PA-CT3/4T1 port adapter has several status LEDs on its faceplate. (See Figure 13.)
Following are the functions of the PA-CT3/4T1 port adapter LEDs:
For additional functions of the status and alarm LEDS, refer to the section "Using Status and Alarm LED Indications".
The individual 1, 2, 3, and test LEDS next to each T1 port indicate the following: This green LED will go on when the respective port is enabled. When the port is not enabled, the LED is off.
The remaining five LEDs, between the TEST and T3 ports, indicate the following:
Observe the LED states and the console displays as the router initializes. When the system has reinitialized all interfaces, the enabled LED on the PA-CT3/4T1 port adapter should go on.
The console screen will also display a message as the system discovers each interface during its reinitialization. After system initialization, the enabled LED goes on to indicate that the PA-CT3/4T1 port adapter is enabled for operation.
The following conditions must be met before the PA-CT3/4T1 port adapter is enabled:
If any of these conditions is not met, the enabled LED does not go on.
Verify that the PA-CT3/4T1 port adapter is connected correctly as follows:
Step 1 While the system reinitializes each interface, observe the console display messages and verify that the system discovers the PA-CT3/4T1 port adapter. The system should recognize the PA-CT3/4T1 port adapter's interfaces but leave them configured as down.
Step 2 When the reinitialization is complete, verify that the enabled LED on the PA-CT3/4T1 port adapter is on and remains on. If the LED does stay on, proceed to Step 5. If the enabled LED does not stay on, proceed to the next step.
Step 3 If the enabled LED on the PA-CT3/4T1 port adapter fails to go on, suspect the that the PA-CT3/4T1 port adapter board connector is not fully seated in the backplane. After the system reinitializes the interfaces, the enabled LED on the PA-CT3/4T1 port adapter should go on. If the enabled LED goes on, proceed to Step 5. If the enabled LED does not go on, proceed to the next step.
Step 4 If the enabled LED still fails to go on, remove the PA-CT3/4T1 port adapter and try installing it in another available port adapter slot.
Step 5 Use the show interfaces command to verify the status of the PA-CT3/4T1 port adapter's interfaces. (If the interfaces are not configured, you must use the procedures in the section "Configuring the T3 and T1 Interfaces", which are not available until you configure them.)
If an error message displays on the console terminal, refer to the appropriate reference publication for error message definitions. If you experience other problems that you are unable to solve, contact a service representative for assistance.
If you installed a new PA-CT3/4T1 port adapter or if you want to change the configuration of an existing controller, you must enter the Configuration mode. If you replaced the PA-CT3/4T1 port adapter that was previously configured, the system will recognize the new PA-CT3/4T1 port adapter and bring it up in the existing configuration.
After you verify that the new PA-CT3/4T1 port adapter is installed correctly, use the privileged-level configure command to configure the new PA-CT3/4T1 port adapter controller. Be prepared with the information you will need, such as the following:
For a complete summary of the configuration options available and more detailed instructions for configuring the PA-CT3/4T1 port adapter controller, refer to the appropriate configuration publications, which are listed in the section "If You Need More Information".
Before you can use the configure command, you must enter the privileged level of the EXEC command interpreter with the enable command. The system will prompt you for a password if one has been set.
The system prompt for the privileged level ends with a pound sign (#) instead of an angle bracket (>). At the console terminal, enter the privileged level as follows:
Step 1 At the user-level EXEC prompt, enter the enable command. The EXEC prompts you for a privileged-level password as follows:
Step 2 Enter the password (the password is case sensitive). For security purposes, the password is not displayed.
Step 3 When you enter the correct password, the system displays the privileged-mode system prompt (#) as follows:
Proceed to the following section to configure the PA-CT3/4T1 port adapter controller.
The interface numbering scheme for the PA-CT3/4T1 port adapter's T1 interfaces is in the form of slot/port:t1 channel where slot refers to the chassis slot in which the PA-CT3/4T1 port adapter is installed; port refers to the physical port on the PA-CT3/4T1 port adapter and is always 0; and t1 channel is a number between 1 and 28. (Refer to the section "Configuring the T3 and T1 Interfaces", for more specific interface configuration information.)
Designate and turn on an external T1 port (one of the three DB-15 connectors labeled 1 through 3) using the t1 external channel command, where t1 channel is a number between 1 and 3.
Designate and turn on the T1 test port (the DB-15 connector labeled TEST) using the t1 test channel command, where t1 channel is a number between 1 and 28.
Following are examples of PA-CT3/4T1 port adapter interface port numbering and sample displays:
The following sample display shows the events logged by the system as the PA-CT3/4T1 port adapter was removed from slot 3; the system then reinitialized the remaining port adapters and marked as down the PA-CT3/4T1 port adapter when it is installed in slot 5. When the PA-CT3/4T1 port adapter was reinserted, the system marked the interfaces as down again because the PA-CT3/4T1 port adapter interfaces were not shut down before the PA-CT3/4T1 port adapter was removed.
Router# %OIR-6-REMCARD: Card removed from slot 3, interfaces disabled %LINK-5-CHANGED: Interfaces T1 3/0, changed to administratively down
When a new PA-CT3/4T1 port adapter is inserted, or when a PA-CT3/4T1 port adapter whose interfaces are shut down is moved to a new slot, the system recognizes the PA-CT3/4T1 port adapter controller, but leaves its interfaces in a shutdown state until you configure them and change the state to up with the configure command. If you move a PA-CT3/4T1 port adapter to a new slot and its interfaces were not shut down, the system recognizes them as not shut down when the PA-CT3/4T1 port adapter is installed in the new slot.
The following example display shows the events logged by the system as a new PA-CT3/4T1 port adapter is inserted in slot 5:
Router# %OIR-6-INSCARD: Card inserted in slot 5, interfaces administratively shut down %LINK-5-CHANGED: Interfaces T3 5/0, changed to administratively down Router#
The following steps describe basic configuration guidelines and configuration command examples for the T3 and then T1 interfaces. Press the Return key after each step.
Following are the steps to configure the T3 interface:
Step 1 At the privileged-mode prompt, enter Configuration mode and specify that the console terminal will be the source of the configuration subcommands as follows:
Step 2 Specify the controller to configure by entering the subcommand controller, followed by t3, and slot/port (port adapter slot number/interface port number). The example that follows is for the PA-CT3/4T1 port adapter in port adapter slot 3for T3 channel 0:
Step 3 At the prompt, specify the framing type using the framing [c-bit | m23 | auto-detect] command: set c-bit framing format, as follows:
At the prompt, request the PA-CT3/4T1 port adapter to detect the framing type it is to receive from the far end, as follows:
Step 4 Specify the cable length using the cablelength feet command, where feet is expressed as a numeral from 0 to 450, with the default value of 224 feet. Issue the cablelength command as follows:
Step 5 Specify the clock source for the controller using the clock source [internal | line] command, which determines which end of the circuit provides the clocking.
If the PA-CT3/4T1 port adapter is not connected to an external clock source, you must use the internal option.
Maintenance Data Link (MDL) messages (which are defined in the ANSI T1.107a-1990 specification) can be configured on the PA-CT3/4T1 port adapter.
To configure MDL messages, use the following controller configuration commands:
mdl {transmit {path | idle-signal | test-signal} | string {eic | lic | fic | unit | pfi | port | generator} string}where the command arguments are defined as follows:
Use the no form of this command to remove message. The default is that no MDL message is configured.
Following are examples of configuring MDL messages; enter controller Configuration mode first, as follows:
Router# conf t
Enter configuration commands, one per line. End with CNTL/Z. Router(config)# cont t3 5/0
Router(config-controll)#
Router(config-controll)# mdl string eic router A
Router(config-controll)# mdl string lic test network
Router(config-controll)# mdl string fic buidling b
Router(config-controll)# mdl string unit abc
Router(config-controll)# mdl string pfi string
Router(config-controll)# mdl string port string
Router(config-controll)# mdl string generator string
Router(config-controll)# mdl transmit path
Router(config-controll)# mdl transmit idle-signal
Router(config-controll)# mdl transmit test-signal
Following are the guidelines for configuring the logical T1 interfaces using controller configuration commands. Examples follow:
Step 1 Specify the channel and timeslots to be mapped using the t1 t1 channel timeslots range [speed {56 | 64}] command.
Where T1 channels are 1-28, range supports contiguous timeslots as well as arbitrary timeslots, and a speed of 56 Kbps is only valid for T1 21-28 (default is 64 Kbps).
Examples follow:
Configure T1 1for full T1 bandwidth, as follows:
Configure the T1 20 to use timeslots 1 through 5 and timeslots 20 through 23 as follows:
Configure the T1 21 for 24 x 56 Kbps as follows:
Step 2 Specify the T1 framing format using the t1 t1 channel framing [esf | sf] command. The default is the extended super frame (ESF) framing format, and T1 channel is 1-28.
Examples follow:
Set super frame (SF) framing format for T1 6 as follows:
Set ESF framing format for T1 18 as follows:
Step 3 Specify remote T1 line code using the t1 t1 channel linecode [ami | b8zs] command. The default is b8zs, and the T1 channel is 1-28.
An example follows:
Step 4 Specify the T1 clock source using the t1 t1 channel clock source [internal | line] command, where the T1 channel is 1-28, and the default is network (line) clocking.
Examples follow:
Set internal clock source for T1 6 as follows:
Set network clock source for T1 1 as follows:
To remove a T1 channel, use the no t1 t1 channel timeslots 1-24 command, where the T1 channel is 1-28. For example, remove the channel for T1 20 as follows:
Router(config-controll)# no t1 20 timeslots 1-24
The following controller configuration commands are valid only to the first three T1 channels (T1 1 through 3) when they are broken out to the external T1 port. Configure a T1 Interface as an external port using the t1 external t1 channel [linecode {b8zs | ami}] [cablelength feet] command, where external T1 channels are 1-3, and the cable length range is 0-655 feet. The default values are as follows: line code is B8ZS; cable length is 133 feet.
(Use the show controller t3 command to check the status of the external ports; refer to the example of this command on page 34 of the section "Command Descriptions and Examples".)
For example, configure T1 1 to be an external port as follows:
Router(config-controll)# t1 external 1 linecode ami cablelength 300
To remove a T1 interface from an external port, use the no t1 external t1 channel command, where external T1 channels are 1-3.
For example, remove T1 1 from external port 1 as follows:
Router(config-controll)# no t1 external 1
The following controller configuration commands are valid only to the T1 test port. Configure the T1 test port using the t1 test t1 test channel [linecode {b8zs | ami}] [cablelength feet] command, where the T1 test channels are 1-28, and the cable length range is 0-655 feet. The default values are as follows: line code is B8ZS; cable length is 133 feet.
(Use the show controller t3 command to check the status of the test port; refer to the example of this command on page 34 of the section "Command Descriptions and Examples".)
For example, bring T1 20 to the test port as follows:
Router(config-controll)# t1 test 20 lincecode ami cablelength 300
To remove a T1 port from the test port, use the no t1 test t1 test channel command, where T1 test channels are 1-28.
For example, remove T1 20 from the test port as follows:
Router(config-controll)# no t1 test 20
Following are additional commands required to complete the PA-CT3/4T1 port adapter configuration:
Step 1 Assign an IP address and subnet mask to the interface with the ip address configuration subcommand as in the following example:
Step 2 Add any additional interface subcommands required to enable routing protocols and adjust the interface characteristics.
Step 3 After including all of the interface subcommands to complete the configuration, press Ctrl-Z (hold down the Control key while you press Z) to exit the configuration mode.
Step 4 Write the new configuration to memory as follows:
The system displays an OK message when the configuration is stored.
Step 5 Exit the privileged level and return to the user level by entering disable at the prompt as follows:
Proceed to the following section to check the interface configuration with show commands.
After configuring the new interface, use the show commands to display the status of the new interface or all interfaces. Using the show controller T3 slot/port:t1 channel command, display T3 or T1 channel information as follows, where the T1 channel is 1-28:
Router# show controller t3 5/0
Router # show controller t3 5/0:5
Router# show controller t3 5/0 remote performance
Router # show controller t3 5/0 brief
Following are descriptions and examples of the show commands. Descriptions are limited to fields that are relevant for verifying the configuration.

The following procedure summarizes how to use the show commands to verify that a new PA-CT3/4T1 port adapter interface is configured correctly:
Step 1 Use the show version command to display the system hardware configuration. Ensure that the list includes the new PA-CT3/4T1 port adapter network interface.
Step 2 Display the T1 alarm condition with the show controllers T3 command.
Step 3 Specify the new interface with the show interfaces command and verify that the first line of the display specifies the serial interface with the correct slot, port adapter, and port. Also verify that the interface and line protocol are in the correct state: up or down.
Step 4 Display the protocols configured for the entire system and specific interfaces with the command show protocols. If necessary, return to the configuration mode to add or remove protocol routing on the system or specific interfaces.
Step 5 Display the entire system configuration file with the show running-config and show startup-config commands. Verify that the configuration is accurate for the system and each interface.
If the interface is down and you configured it as up, or if the displays indicate that the hardware is not functioning properly, ensure that the network interface is properly connected and terminated.
This completes the configuration procedure for the new PA-CT3/4T1 port adapter interface.
Following are suggested guidelines for troubleshooting the PA-CT3/4T1 port adapter using the loopback command, LED indications, a bit error test (BERT), FDL performance reports, and for displaying remote performance reports.
Should you have difficulty with the PA-CT3/4T1 port adapter configuration or installation, you can troubleshoot the PA-CT3/4T1 port adapter using the loopback command. Specify loopback for a T1 channel using the t1 channel loopback command, where the T1 channel is 1-28. There are three main loopback modes as follows: local, network (both line and payload), and remote (line and payload). Specify the loopback format using the loopback [local | network | remote] command.
Examples of specific loopback modes follow:
Router# config t
Enter configuration commands, one per line. End with CNTL/Z. Router(config)# interface serial 3/0:1
Router(config-if)# loopback local
Router# config t
Enter configuration commands, one per line. End with CNTL/Z. Router(config)# interface serial 3/0:1
Router(config-if)# loopback network line
Router# config t
Enter configuration commands, one per line. End with CNTL/Z. Router(config)# interface serial 3/0:1
Router(config-if)# loopback network payload
loopback [remote {line {fdl ansi | inband} | payload fdl ansi}]
Router# config t
Enter configuration commands, one per line. End with CNTL/Z. Router(config)# int serial 3/0:1
Router(config-if)# loop remote line inband
Router# config t
Enter configuration commands, one per line. End with CNTL/Z. Router(config)# int serial 3/0:1
Router(config-if)# loop remote line fdl ansi
Router# config t
Enter configuration commands, one per line. End with CNTL/Z. Router(config)# int serial 3/0:1
Router(config-if)# loop remote payload fdl ansi
Following are various system states and functions that are reflected by the front-panel alarm and status LEDs on the PA-CT3/4T1 port adapter during the CPU boot process and microcode download.
1 After the PA-CT3/4T1 port adapter CPU has booted successfully, the alarm and status LEDs goes on.
2 When the PA-CT3/4T1 port adapter microcode download begins, the alarm LED goes off while the status LED flashes on and off.
3 After the PA-CT3/4T1 port adapter microcode is downloaded (and before the PA-CT3/4T1 port adapter microcode image boots) the status LED goes off.
During the system bootup process and microcode download, the following LED error indications might appear:
In all the preceding error modes, the CPU continually loops and the system does not proceed to the microcode download.
To check bit errors using a bit error test (BERT), use the following command:
[no] t1 t1 channel bert pattern {2^15 | 2^20 | 2^23 | 0s |
1s} interval minutes
where t1 channel is 1-28, 2^15 is an exponential number that represents a pseudo-random repeating pattern that is 32767 bits long, 2^20 is a pseudo-random repeating pattern that is 1048575 bits long, 2^23 is a pseudo-random repeating pattern that is 8388607 bits long, 0s is a pattern of all zeroes (00000000...), 1s is a pattern of all 1s (111111...), and minutes are 1-14400, which designate the time the BERT will run. To stop the BERT, use the optional no form of the command. Following is an example of this command, where the pseudo-random pattern 2^20 is sent and repeats on the first T1 channel for 60 minutes:
Router# t1 1 bert pattern 2^20 interval 60
Note that the BERT command is not saved in NVRAM. The test patterns from the PA-CT3/4T1 port adapter are framed test patterns; therefore, they are inserted into the payload of a framed T1 signal.
To display the BERT results, use the following EXEC commands: sh cont t3 number or sh cont t3 number brief. Following are examples of displaying BERT results output:
