This section discusses installation procedures for a direct connect configuration. The basic cabling configuration and a table showing cable types and part numbers are also presented in this section.
This section provides an illustration showing the cabling requirements for the direct connect configuration of the Cisco 6100. This section also contains a table showing cable part numbers identified for the direct connect configuration.
The following is an illustration of the basic cabling of the direct connect configuration of the 6100. Some connectors are not used because they are specific to one of the other configurations of the 6100 or because they have been reserved for future use.
The following table lists the cables and their associated part numbers for the direct connect configuration of the 6100.
The pinouts for these cables can be found in Table A-1 (J39-J44), Table A-8 (J3-J6), and Table A-9 (J1-J2).

If you are installing a subtended network, please see the "Installation - Subtended Network" chapter when you complete these steps.
Bolt the empty chassis into the relay rack. Make sure you leave a 1U space between the MC and the first PSC to allow for cabling from the back to the front.
The MC chassis (9U) should be at the top of the rack followed by one or more PSCs (4U each).
Connect the 50-pin CHAMP cables from the MC (J39 -J44) to the PSC (J1 - J6). These connections are for ADSL data flow between the MC and the PSC.
The PSC has three sets of connections for:
Refer to the following figure for the location of these connectors.
See Figure 7-1 for an illustration of the cabling between the MC and the PSC for the direct connect configuration. See Table A-1 for a description of the pinouts for MC connectors J39-J44. See Table A-8 for a description of PSC connectors J3-J6, and see Table A-9 for a description of PSC connectors J1 and J2.
The one requirement for grounding to be considered during installation is grounding the chassis to the rack.
Chassis grounding must be provided by using the grounding clips (compression screw) provided. The grounding clips are located in the upper left hand corner of each chassis when viewed from the rear.
You should use 14 gauge stranded wire or thicker and verify that all paint or oxidation has been removed from the frame at the point of the grounding connection.
The left side of Figure 7-3 illustrates the grounding of the MC and PSCs to the rack.
Connect the power terminal block connector inputs on the MC (P13) to the fuse/alarm panel located at the top of the rack. Wire up the -48V power feeds from the fuse and alarm panel to the MC.
External power is supplied to the system as -48V from the Central Office (CO) MDF to the fuse/alarm panel. Power is fed from the fuse/alarm panel to the MC through a 4-position terminal block (P13) located at the top of the MC back panel. Figure 7-4 shows the location of the P13 connector.
 | Warning To prevent the system from being powered, the fuses should NOT be installed at this time. If the fuses have already been installed, they should be removed. Fuses can be replaced after the system is wired. |
The nominal amperage for the MC is 7 amps. In a typical CO, the amperage and fusing is factored by 1.25. Therefore, each MC should have a 10 amp fuse. Figure 7-5 illustrates the fusing connections.
See Figure A-6 for an illustration of the P13 power terminal block on the MC.
The power returns from the chassis to the fuse/alarm panel should be wired as illustrated in Figure 7-6.
Connect the Alarm contacts to the E2A, visual, and audible (P14, P15, P17) alarm connections on the MC backplane. There are wire wrap alarm contacts for three alarm types: critical, major, and minor.
The alarm interface provides three types of alarm contacts: E2A, visual, and audible. Each connector provides a dedicated side-by-side pair of contacts for critical, major, and minor alarm contacts. The critical alarm contacts are normally closed to allow critical alarms to activate a CO alarm in the event of a loss of power to the 6100 system. That is, if power is lost, the critical alarm contacts will open, causing a CO alarm to be activated. The major and minor alarm contacts are normally open.
Typically, audible and visual alarm contacts are used to connect to CO alarm systems. E2A contacts are designed to connect to a standardized management interface for intra-office alarm transport.
An automatic cut off (ACO) input is also located adjacent to the audible alarm contacts. The ACO input deactivates audible alarm contacts when closed. The system controller (SC) module front panel contains a button labeled ACO that you can press to disable the CO audible alarms on site. All alarm contacts are rated at 2 amps maximum current and 220 VDC maximum voltage.
The following figures show the location of the alarm interface connectors on the MC rear panel and provide a close-up of the connector pinouts.
See Figure A-8 for an illustration of the MC alarm contact connectors. Table A-3 shows the pinouts for the E2A (P14), Visual (P15), and Audible (P17) alarm contacts.
The 6100 is shipped with the system I/O card already installed on the rear of the MC. If the card is missing from your system, install it at connector locations P9 and P3. (See Figure 4-1 for the location of these connectors and Table 4-3 for a description of the connector.)
The system I/O card provides the 10BaseT ethernet connector for the system management interface to a PC or UNIX system and external clock wire wrap pins.
Also located on the system I/O card are coaxial connections for DS3 cabling when a DS3 NI module is installed. If no DS3 NI is present, the coaxial connections are not used. See the "Connecting the Network Interface" section for more information on the NI modules.
The following figure is an illustration of the system I/O card:
The Cisco 6100 can be timed from one of three places:
External BITS clock connection. Connect the external 1.544 MHz clock source (if required) to the external clock input (wire wrap pins at location P5 on system I/O card). The external clock interface is located on the system I/O board at P5 on the rear panel of the multiplexer chassis. The interface consists of two wire wrap contacts. Each contact is labeled either tip or ring. Tip contacts are connected to the tip wire contact from the CO. Ring contacts are connected to the ring wire contact from the CO.
The clock interface allows the CO to connect the 6100 to an external clock source. The external clock provides a timing reference for the 6100 system. The electrical interface for the external clock should be a 100-ohm twisted pair 1.544 MHz T1 bipolar signal.
The following figure shows the external clock interface wire wrap contacts on the system I/O card.
Using the special cables provided by Cisco or built according to the specifications for a Nortel NT-T100 Series cable, punch down the PSC line connectors (J11-J14) to the 66 Block. Then punch down the slot/line tip/ring pairs to the standard CHAMP color mapping for the MDF. Connect the voice connectors (J7-J10) to the POTS class 5 switch. The data connectors (J3-J6) go to the MC data connectors.
Figure 7-11, Table 7-3, Figure 7-13, and Figure 7-14 provide the information required to trace any single connection from a particular slot/line of the PSC to the outside world.
Figure 7-11 illustrates the connectors used to connect from the PSC through to the Class 5 Switch (through the MDF). In the illustration, slots 1-10 support up to 40 subscribers, and slots 13-22 support up to 40 more subscribers. The first 40 subscribers can be traced through punch down block A, and the second 40 subscribers can be traced through punch down block B.
Knowing that connector J11 on the PSC services slots 1-5 in the chassis, you can consult Table 7-3 for the tip and ring information for any particular slot/line. For example, slot 1, line 1 off the PSC is 1-1 tip = pin 9 and 1-1 ring = pin 34. The wire colors for slot 1 (line 1 tip/ring going to the 66 block) are 1-1 tip = RED/BRN and 1-1 ring = BRN/RED. Once the wires are punched down to the appropriate 66 block connectors and wired to the outside world, you should be able to trace a connection from the MC slot/port through to the outside subscriber line. Figure 7-13 shows the 66 block wire wrap tip/ring map for connectors J7, J9, J11, and J12, and see Figure 7-14 shows the 66 block wire wrap tip/ring map for connectors J10, J8, J13, and J14.
Table A-7 shows the pinouts for subscriber line connectors J11-J14 and Table A-6 shows the pinouts for the POTS connectors J7-J10.
Apply power to the system by installing fuses or turning on breakers in the fuse/alarm panel (whichever is applicable). The power returns from the chassis to the fuse/alarm panel should be wired as illustrated in Figure 7-7. Check the polarity of the -48VDC connections to each chassis by attaching a voltmeter with the minus lead on -48 RTN and the plus lead on -48 VD_A. The meter should read between -36VDC and -60VDC.
 | Warning Installing modules in the 6100 system with the power leads reversed may cause damage to the modules. |
After the rack, chassis, and basic cables are installed, install the 6100 modules in the following order to ensure that auto-discovery works properly. (See the ViewRunner for Windows Provisioning and Operation Manual for more information on the auto-discovery feature.)
 | Caution Proper electrostatic discharge (ESD) protection is required at all times when handling modules. Installation and maintenance personnel should be properly grounded via ground straps to eliminate the risk of ESD damage when handling modules. Modules are subject to ESD damage upon removal from their anti-static shipment bag. |
See the "Front Panel Status Indicators" chapter for more information on installing the DS3 subtending module for subtended systems.
The ATU-C modules are jumpered differently between the DOH configurations and the direct connect configuration. The proper placement of the ATU-C jumpers for the direct connect configuration is shown in the following figure. The orientation of the figure shows the front panel of the module to the left and the backplane connections to the right.
See Figure 5-16 for information about the DOH standard configuration and ATU-C jumpering.
The xDSL protection bus jumper, in conjunction with DIP switches SW1 and SW2, on the MC let you designate one or two backup (redundant) ATU-C slots in the MC. Slots 20 and 38 may be configured as redundant slots, in either 1:15 or 1:31 configurations. For 1:15 configurations, the ATU-C in slot 20 serves as a backup module for ATU-Cs in slots 1-8 and 13-19; the ATU-C in slot 38 backs up ATU-Cs in slots 21-28 and 31-37. For 1:31 configurations, the ATU-C in slot 20 serves as a single backup card for all other ATU-Cs in the MC.
For 1:15 redundancy, you can make slots 20 and 38 redundant slots by setting all switches on SW1 and SW2 to the ON position and moving the protection bus shunt to the 1:15 position as shown in Figure 7-16.
For 1:31 redundancy, you can make slot 20 redundant by setting all switches on SW1 to the ON position, and moving the protection bus shunt to the 1:31 position as shown in Figure 7-16. All switches on SW2 should be set to the OFF position, thereby allowing slot 38 to be used as a primary ATU-C slot (see Figure 7-17).
Although not required for system operation, filler faceplates must be installed in all open slots of each chassis to meet UL 1950, Issue 3 safety requirements.
Validate the continuity of the wiring/cabling between the Public Switch Telephone Network (PSTN) and the MDF to the PSC. Table 7-3 describes the procedures to determine whether or not the following connections exist:

In addition to the above continuity testing, a 2-wire analog test interface is provided for attaching external ADSL test equipment. Using this interface, test tones may be injected towards the subscriber line, or internally towards the ATU-Cs. Two methods are provided for attaching external ADSL test equipment to the 6100:
Figure 7-18 shows the test interface connectors on the MC rear panel, and Figure 7-19 shows the test interface plug-in jack on the front of the SC.
Plug the NI module into slot 10 on the MC.
The 6100 NI module provides three types of network connections:
The OC3c interface connections are located on the front panel of the NI modules and consist of two SC-type optical connectors. Refer to Figure 7-20 to see the OC3c interface connector on the NI module.
If you are using an OC3c single- or multi-mode NI, connect the NI transmit and receive cables from the ATM switch through the 1U space between the MC and the first PSC. Connect the optical fiber to the transmit and receive connectors in the inset on the front panel of the NI modules. The transmit connector is the one closest to the top of the front panel and closer to the faceplate, and the receive connector is closest to the bottom of the module and farthest from the faceplate. Silkscreening inside the inset identifies which connector is which. The fiber is coiled loosely within the 1U space to take out slack.
The reach for the single-mode fiber (SMF) interface is specified to 35Km, using Siecor .20dB per Km, 9uM optical cable. The electro-optical characteristics of the single-mode 155 MBd ATM transceiver 2x9 are as follows:
| Transmitter | Units | Min | Typ | Max |
|---|---|---|---|---|
Output Power (average) | dBm | -15.0 | -11.0 | -8.0 |
Center WaveLength | nm | 1260 |
| -1360 |
For single-mode ATM/SONET/SDH transceivers (0° to +70°C fiber), the receiver minimum optical input power is -31 dBm (avg.), and the receiver maximum optical input power is -8 dBm (avg.).
The electro-optical characteristics of the multi-mode OC3 transceiver are as follows:
| Transmitter | Units | Min | Typ | Max |
|---|---|---|---|---|
Output Power (average) | dBm | -17.0 | -15.0 | -12.0 |
Center WaveLength | nm | 800 |
| -900 |
The DS3 NI connections are on the system I/O plug-in card that is located on the rear panel of the MC. They connect to the ATM switch. Two 75-ohm BNC connectors are provided for DS3 transmit and receive.
The DS3 NI gets its transmit timing from a local oscillator with 20 ppm accuracy. The line build out defaults to 0 to 250 feet.
The default configuration for the DS3 NI is as follows:
Refer to the following figure for an illustration of these connectors.
If you are using a DS3 NI, connect the cable from the ATM switch to the BNC connectors on the system I/O card on the rear panel of the MC. The bottom BNC connector (J3) (the closest to the ethernet connector) is for transmit and the top connector (J4) is for receive.
Cisco recommends that ferrite beads be added to the coaxial cables used to cable the DS3 system I/O card to the ATM switch (or to the DS3 subtend card - see the "Cabling the System I/O Card to the DS3 Subtend Card" section) to reduce the radiation/EMI susceptibility to high frequency noise between 30 and 200 MHz.
Using either the ferrite beads shipped with the DS3 NI module (type 43) or ones that use ferrite material type 43 or 44 with an impedance of >200 ohms +/-20% at 100 MHz, attach the beads close to both the transmit and receive BNC connectors on the system I/I card. See Figure 5-22 for the location of the BNC connectors.
If you are using thick type 734A coaxial cable, run the cable through the ferrite bead and clamp it shut, as shown in Figure 7-22.
If you are using thin type 735A coaxial cable, run the cable through once, then loop it back through the ferrite bead and clamp it shut, as shown in Figure 7-23.
Figure 7-24 shows the ferrite beads on the coaxial cable close to the BNC connectors on the system I/O card.
Connect one end of the management cable to the RJ-45 (10BaseT) connector on the rear panel of the MC system I/O card. Connect the other end to a PC running ViewRunner for Windows, to a UNIX system running ViewRunner for OpenView, or to your ethernet LAN. Figure 7-25 illustrates the location of the RJ-45 connector on the system I/O module. See the ViewRunner for Windows Provisioning and Operation Manual for information on how to validate the connection.
Two ViewRunner management interface connections are provided on the system I/O card on the 6100 MC:
The MC connects to the Management Interface via a 10BaseT ethernet cable. One end of the management cable connects to an RJ-45 8-position connector on the MC system I/O card. This card is located on the rear panel of the MC. The other end of the cable connects to a PC running ViewRunner for Windows, to a UNIX workstation running ViewRunner for Open View, or to the Ethernet LAN. Refer to Figure 7-21 to see the location of the RJ-45 connector on the system I/O card on the MC rear panel and the 9-pin connector on the front of the SC.
The Cisco 6100 also supports a local craft interface for laptop or VT-100 terminal usage. The local craft interface is supported via a 9-pin D-sub serial connector on the face plate of the SC module. A straight through RS-232 management cable runs from the SC module's 9-pin D-sub connector to a corresponding 9-pin D-sub connector (J29). The port access settings are as follows:
This connection is used to establish a serial interface for the command line interface (CLI) which allows up to 7 people, via 1 serial session and 6 Telnet sessions, to manage a 6100 system. The CLI has a series of commands allowing the user to view status and configuration details of any entity within a 6100 and to modify certain system attributes. Currently only the Show Alarms commands are supported. See the ViewRunner for Windows Provisioning and Operations Manual for more information about the CLI.
