Central Office (CO) Side Connections
CO side connections can be made in one of two ways. One way
is through the wirewrap pins inside the enclosure on the Telco
Termination Module (J1 through J14 on the module) and
another way is by two 25-pair Amphenol cable connectors at
the rear of the enclosure. Either method limits customer access
to these connections, with the wirewrap pin method being the
most secure (requires a key for access).
3.6.1
J1 - J14 Connector Wirewrap Pins
CO side (network/facility) connections are typically made to J1
through J14, the wirewrap connector pins on the Telco Ter-
mination Module shipped with every enclosure and installed
behind the locked front door in the top slot of the enclosure.
Each Telco Termination Module has 14 J-connectors, one for
each DNI/ HDSL module slot in the enclosure (see Figure 7).
Each of the 14 J-connectors has six wirewrap pins; one pin is not
used (NC) and five are labelled R1, T1, R, T, and SGND.
Table 2 lists the connections that can be made by wirewrapping
the appropriate leads from the network to the proper pins of
each connector. Connections should be made using twisted
shielded pair cable of a gauge consistent with local installation
practices.
3.6.2
25-Pair Male Amphenol Connectors
An alternate method of making CO side (network/facility) con-
nections is through the high-density, 25-pair, male, Amphenol
connectors, XMT and RCV, at the rear of enclosure on the en-
closure back panel. Network transmit and receive signals are in
separate connectors, labelled XMT and RCV. By ordering list
option S", two 15-foot long, female-to-stub-ended Amphenol
cables will be shipped with the enclosure.
