3.1 NEBS Compliance Cabling Guidelines
To comply with NEBS requirements, ensure that all cables are screw fastened onto backplane
receptacles and that the cable Champ connectors are tie wrapped (Figure 3-1).

3.2 Required Cables for Installation with POTS Splitter
During an installation with a POTS splitter, use only the Cisco cables specified in Table 3-1 to
connect the Cisco 6130 NI-2 DSLAM, the POTS splitter, and the CO facility MDF. This section
provides tables and illustrations for DSLAM-to-POTS splitter cable connections. Consult Siecor
documentation for line connections from the MDF to the POTS splitter and POTS splitter cabling
from the POTS splitter to the MDF.
Note SomeCisco6130 NI-2DSLAM receptaclesinthe cablingdiagrams arenotused because they
are specific to one of the other Cisco 6100 DSLAM system configurations or because they are
reserved for future use.
3.2.1 Making DSLAM-to-POTS Splitter Cable Connections
To connect the Cisco 6130 multiplexer chassis (MC) to the POTS splitter in installations with a
POTS splitter, use one-to-one Cisco Champ cables. Use one-to-one cables to connect the POTS
splitter xDSL outputs to the Cisco 6130 NI-2 multiplexerchassis ADSL inputs for DSLAM systems
with quad-port DMT-2 ATUC-1-4DMT modules.
Table 3-2 lists the backplane connectors and part number for the Cisco one-to-one cable kit that
permits you to connect the POTS splitter to the chassis (Cisco 6130 NI-2 DSLAM) backplane
receptacles in installations with a POTS splitter.

3.3 Required Cables for Installation without POTS Splitter
In an installation without a POTS splitter, use only designated cables to connect the Cisco 6130 NI-2
DSLAM and the CO facility MDF. The illustrations in this section show you how to connect
three-to-three cables.
Note Some chassis connectors in the cabling diagrams are not used because they are specific to a
different Cisco 6100 series NI-2 DSLAM system or because they are reserved for future use.
3.3.1 Using Three-to-Three Cables
Toassociate the CO facility MDF wire pairs and the DSLAM modem ports, the three-to-three cables
remap wire pairs from the Cisco 6130 NI-2 DSLAM Champ connectors to the CO facility MDF
Champ receptacles.

three-to-three Champ cable connectors between the DSLAM and the CO facility MDF in an
installation without a POTS splitter.

3.4 Required Cables for Subtended Network Configuration
In subtended network configurations, use only designated cables to connect DS3 system I/O card
BNC connectors for subtending.
A single DS3 system I/O card, installed on the Cisco 6130 NI-2 DSLAM backplane, permits up to
12 DS3 configured Cisco 6130 NI-2 DSLAM systems to be subtended. Figure 3-5 shows basic
cabling of a typical subtended DS3 configured network.

Note Some system I/O card connectors might not be used because they are specific to a particular
configurations of subtended Cisco 6130 NI-2 DSLAMs or are reserved for future use.
