This chapter provides Network Equipment Building Systems (NEBS) compliance cabling guidelines. This chapter also provides cabling configuration diagrams and part numbers for the following:
 | Warning Only trained personnel should install, replace, or service this equipment. |
If you are using quad-port ATUC-1-4DMT modules, you can use one-to-one multiplexer chassis cables. The one-to-one cables are recommended for all new installations.
For detailed port mapping tables, see "Connectors, Pinouts, and Port Mapping." This appendix includes port mapping tables for building and connecting Cisco 6130 DSLAM chassis cables.
Table 3-1 shows an overview of the cables used for the Cisco 6130 NI-2 DSLAM configuration.
| Configuration | Connection | Cable Type | Ports | Line Coding Technology | Reference | ||
|---|---|---|---|---|---|---|---|
| DSLAM | POTS Splitter | Table | Figure | ||||
Installation with a POTS splitter | Siecor POTS splitter to DSLAM | One-to-one1 | 128 | 128 | DMT-2 (ADSL) | ||
Installation without a POTS splitter | DSLAM to MDF | Three-to-three2 | 128 | --- | DMT-2 (ADSL) | Figure 3-2 and Figure 3-3 | |
| 1Six are required. 2Two are required, one left and one right. |
To comply with NEBS requirements, ensure that all cables are screwed in to the backplane and that all Champ connectors are tie wrapped. (See Figure 3-1.)
In an installation without a POTS splitter, use only designated cables to connect the Cisco 6130 NI-2 DSLAM chassis with the main distribution frame (MDF). This section provides tables and illustrations for the required three-to-three cables.
To associate the MDF wire pairs with the chassis modem ports, the three-to-three cables remap the wire pairs from the Cisco 6130 NI-2 DSLAM chassis connectors to the CO facility MDF connectors. Use the three-to-three cables in systems with quad-port ATUC-1-4DMT modules installed in the chassis. Table 3-2 lists the backplane connectors and the part numbers for the three-to-three cables that connect the Cisco 6130 DSLAM chassis to the MDF in an installation without a POTS splitter.

| Chassis | MDF | Kit | Subassembly |
J39, J40, J41 | P4 (slots 1 to 6), | CAB-MC128-MDF | 72-1765-01 |
J42, J43, J44 | P1 (slots 13 to 18), | 72-1720-01 | |
Figure 3-2 shows the three-to-three cable.
Figure 3-3 shows the cabling between the chassis and the MDF in which the cables listed in Table 3-2 are used.
In a subtended network configuration, use only designated cables to connect
This section provides the following:
The system I/O card provides the host chassis with DS3 trunk and subtended network interfaces, as well as CO facility alarms interfaces for DS3 or OC-3 configured chassis. Figure 3-4 shows the basic cabling of the subtended DS3 network configuration with the system I/O card.
Figure 3-5 shows the basic cabling of the subtended network configuration with the OC-3 NI-2 module.
The DS3 BNC connectors on the system I/O card of the subtending host chassis connect directly to the DS3 BNC connectors on the system I/O card of the subtended mode chassis. For OC-3 subtending, the connection is made from the front of the NI-2 module. For more information, see "Installing a Subtended Network."
The Siecor ADSL POTS splitter rack-mount shelf is compatible with the Cisco 6130 NI-2 DSLAM. If you use the Siecor POTS splitter (see Figure 3-6), you need six one-to-one cables to connect the POTS splitter to Cisco MC connectors J39 through J44.
You use one-to-one cables when you are connecting the DSLAM to the POTS splitter in a Cisco 6130 NI-2 DSLAM installation with a POTS splitter. Use one-to-one cables to connect the DSLAM to the POTS splitter for systems with quad-port DMT-2 ATUC-1-4DMT modules. Table 3-3 lists the backplane connectors and the part numbers for Cisco one-to-one cables that you can use to connect the DSLAM to the POTS splitter in an installation with a POTS splitter.

Figure 3-7 shows the one-to-one special cable.
Figure 3-8 shows the one-to-one cabling between the Cisco 6130 NI-2 DSLAM and the POTS splitter. Use the cables listed in Table 3-3 to make these connections. Use the one-to-one cable when you are connecting the chassis to the Siecor POTS splitter.
