Cisco 6100 Series System Cables

This chapter provides Network Equipment Building Systems (NEBS) compliance cabling guidelines, cabling configuration diagrams, and part numbers for the following:

Direct Connect with a POTS splitter chassis (PSC) configuration
Direct Connect without a PSC configuration
Digital Off-Hook (DOH) configuration
Subtended network configuration
Siecor asymmetric digital subscriber line (ADSL) POTS Splitter Rack-Mount Shelf

Note The fan tray backplane (connector P2) is connected to the E2A alarm contact (connector J14, pins 7 and 8) on the multiplexer chassis (MC) backplane. The fan tray alarm contacts will be wired in the installation procedures so that fan tray alarms can be transmitted to the ViewRunner management software. For more information on connecting the fan tray and the MC, refer to either the Cisco 6100 Series Direct Connect Installation Guide.

Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment.

If you are using dual-port ATU-C modules, use 64-port MC cables. However, if you plan to expand your system to quad-port xTU-C modules for future releases, you can use 128-port MC cables to make future expansion easier. The 128-port MC cables are recommended for all new installations.

For detailed port mapping tables, see "Port Mapping." This appendix includes port mapping tables to build MC cables.

Table 3-1 shows an overview of the cables used for each Cisco 6100 Series system configuration.

3.4.2 PSC to MDF Cables

You can use the following cables when you are cabling the PSC to the MDF in a DOH configuration:

One-to-one cables---Used to connect the PSC to the MDF
Two-to-two cables---Used to connect the xDSL subscriber line connections on the PSC (J11 to J14) to the MDF and to connect the voice lines on the PSC (J7 to J10) to the voice switching equipment that provides local POTS service

One-to-One Cables

You can use one-to-one cables to connect the PSC to the MDF or external voice equipment. Table 3-10 lists the backplane connectors, the available cable lengths, and the part numbers for the one-to-one cables connecting the PSC to the MDF in a DOH configuration. Each cable has the same pinouts. The only difference between the four cables is the length. Use the length that works best for your configuration.

Two-to-Two Cables

To associate the PSC MDF wire pairs and the MC modem ports, the two-to-two cable remaps the wire pairs from the PSC MDF connectors to the PSC connectors. You can use the two-to-two cable to

Connect the xDSL subscriber line connections on the PSC (J11 to J14) to the MDF
Connect the voice lines on the PSC (J7 to J10) to the voice switching equipment that provides local POTS service

3.5 Subtended Network Configuration Cables

In a subtended network configuration, use only designated cables to connect the DS3 subtending card to the DS3 system I/O card. This section provides the following:

Cabling diagrams
Cable connections

3.5.1 Cabling Diagrams

Two DS3 system I/O cards are currently available. Figure 3-24 shows the basic cabling of the subtended network configuration with the DS3 system I/O card that is available from Release 2.4.0 and later.

Note Some connectors are not used because they are specific to one of the other configurations of the MC or because they are reserved for future use.

Figure 3-24: Basic Cabling for Subtending from Release 2.4.0 and Later

Figure 3-25 shows the basic cabling of the subtended network configuration with the DS3 system I/O card that is available earlier than Release 2.4.0.

Figure 3-25: Basic Cabling for Subtending Before Release 2.4.0

3.5.2 Cable Connections

The DS3 subtending card on the subtending host MC connects directly to the DS3 system I/O card on the subtended mode MC. You should add ferrites to the DS3 75-ohm coaxial cables that you use to cable the DS3 subtending card to the DS3 system I/O card. Doing so reduces the radiation/EMI susceptibility of the system to high frequency noise, bringing it to a value between 30 and 200 MHz. For more information, refer to the

Cisco 6100 Series Direct Connect Installation Guide for a Direct Connect configuration
Cisco 6100 Set Up and Installation Manual for a DOH configuration

3.6 Siecor POTS Splitter Cables

The Siecor ADSL POTS Splitter Rack-Mount Shelf is compatible with the Cisco 6130. If you use the Siecor POTS splitter, you need six one-to-one cables to connect the POTS splitter to the Cisco MC connectors J39 through J44. This one-to-one cable is not the same as the one-to-one cables used in previous configurations.

Use the one-to-one cable when you are connecting the MC to the Siecor POTS splitter. Table 3-12 lists the cable and associated part numbers.
