Channelized T3 Support for the Cisco  AS5800

Feature Overview

The Channelized T3 (CT3) interface processor and port adapter are available on Cisco AS5800 access servers. This card provides for the aggregation of channelized interfaces into a single T3 facility. T3 support on the Cisco AS5800 allows support for 28 T1s (672 channels) per chassis.

Benefits

Channelized T3 allows increased port density and lower cost per port, and supports a standard, North American service. CT3 support allows users to maximize double-density modem technology in the Cisco AS5800.

Supported Platforms

This feature is supported on the Cisco AS5800.

Supported MIBs and RFCs

None

List of Terms and Acronyms

DS1---The Digital Signal level for T1-class channels.

DS3---The Digital Signal level for T3-class channels.

T1---A North American standard T-Carrier, multiplexed system for channels.

Receiver has loss of signal (LOS). Receiver is getting AIS. Receiver has loss of frame (LOF). Receiver has remote alarm. Receiver has no alarms.
MDL transmission ...	Maintenance Data Link status (either enabled or disabled). Used for carrying performance information and control signals across the network towards the far end T3 unit. It is the counterpart of Facility Data Link (FDL) in a T1 link.
FEAC code received	Whether or not a far-end alarm code request is being received. Possible values are as follows: DS3 Eqpt. Failure (SA) DS3 LOS/HBER DS3 Out-of-Frame DS3 AIS Received DS3 IDLE Received DS3 Eqpt. Failure (NSA) Common Eqpt. Failure (NSA) Multiple DS1 LOS/HBER DS1 Eqpt. Failure Single DS1 LOS/HBER DS1 Eqpts Failure (NSA) No code is being received

Table 3 describes the fields shown in the show interface serial display.

Table 3: show interface serial Command Field Descriptions

Field	Description
Serial slot/port is up/...administratively down	Indicates whether the interface hardware is currently active or administratively down.
line protocol is up/...administratively down	Indicates whether the software processes that handle the line protocol believe the interface is usable or administratively down.
hardware	Hardware type.
MTU	Maximum Transmission Unit (MTU) of the interface. (The MTU for Ethernet is 1500 bytes.)
BW	Bandwidth of the interface in kilobits per second.
DLY	Delay of the interface in microseconds.
rely	Reliability of the interface as a fraction of 255, calculated as an exponential average over 5 minutes. (For example, 255/255 is 100% reliability.)
load	Load on the interface as a fraction of 255, calculated as an exponential average over 5 minutes. (For example, 255/255 is complete saturation.)
Encapsulation	Encapsulation method assigned to this interface.
loopback set/not set	Loopback status.
Last input	Number of hours, minutes, and seconds since the last packet was successfully received by an interface.
output	Number of hours, minutes, and seconds since the last packet was successfully transmitted by an interface.
output hang	Number of hours, minutes, and seconds (or never) since the interface was last reset because of a transmission that took too long. When the number of hours in any of the "last" fields exceeds 24 hours, the number of days and hours is printed. If that field overflows, asterisks are printed.
Last clearing of "show interface" counters	Time at which the counters that measure cumulative statistics (such as number of bytes transmitted and received) were last reset to zero.
Queueing strategy	Displays the type of queueing configured for this interface. In the example output, the type of queueing configured is First In First Out (FIFO).
Output queue	Number of packets in the output queue. The format of this number is A/B, where A indicates the number of packets in the queue, and B indicates the maximum number of packets allowed in the queue.
drops	Indicates the number of packets dropped due to a full queue.

Five minute output rate	Average number of bits and packets transmitted per second in the last five minutes.
packets input	Total number of error-free packets received by the system.

no buffer	Number of received packets discarded because there was no buffer space in the main system.
Received broadcast	Total number of broadcast or multicast packets received by the interface.
runts	Number of packets that are discarded because they are smaller than the medium's minimum packet size.
giants	Number of packets that are discarded because they exceed the medium's maximum packet size.
throttles	Number of times the receiver on the port was disabled, possibly due to buffer or processor overload.
input errors	Includes runts, giants, no buffers, CRC, frame, overrun, and ignored counts.

A CRC error occurs when the CRC value calculated from the data transmitted by the far-end device does not match the checksum value calculated from the data received at the near-end device.
frame	Number of packets received incorrectly having a CRC error and a non-integer number of octets.
overrun	Number of times the receiver hardware was unable to forward received data to a hardware buffer because the input rate exceeded the receiver's ability to handle the data.
ignored	Number of received packets ignored by the interface because the interface hardware ran low on internal buffers.

Timeslot(s) Used	Number of timeslots assigned to the T1 channel.
subrate	Bandwidth of each timeslot.
transmit delay is ...	Number of idle flags inserted between each frame.

Related Commands

t1

To create a logical T1 controller from each of the specified timeslots of the T3 line, use the t1 controller configuration command. Enter the no form of this command to delete the defined logical controller.

Syntax Description

Default

None default behavior or values.

Command Mode

Controller configuration

Command History

Usage Guidelines

The purpose of this command is to convert the collection of the 28 T1 controllers comprising the T3 controller into individual T1 controllers that the system can use. In other words, the Cisco  AS5800 cannot pass data until a T1 controller is configured (using the controller t1 command), and you cannot configure a T1 controller until it has been created using the t1 command.

Example

The following example configures a logical T1 controller at T1 timeslot 1 for the T3 controller located in shelf 1, slot 4, port 0. Note that you have to enter the command from the controller configuration mode.

Router(config)# controller t3 1/4/0
Router(config-controller)# t1 1 controller
Router(config-controller)# end
Router#
