NOTE:

The distinction between facility types is important when using TN1654 circuit packs. The facility used to carry control channel messages between the pair of DS1 converter circuit packs and all packet traffic is known as the primary facility. The facility used to backup and takeover for the primary facility in the event of primary facility failure is known as the secondary facility. The TN1654 allows either facility, A or B, to be a primary channel. The control channel is restricted to only the A or B facilities. This permits full 24-channel access (T1) or 31-channel access (E1) for facilities C and D to support user traffic.

Install the Circuit Pack and Cabling (E1 Only)

The E1 installation is similar to the T1 installation except the H600-348 Quad

Cable and the Channel Service Unit are not used.

NOTE:

The H600-348 Quad Cable can be used on E1, 120 Ohm installations.

1.Install a “Y” cable between the DS1 Converter connector and the Expansion Interface connector. See Figure 5-12. Also refer to Table 5-10 for the “Y” cable lengths and associated comcode numbers.

2.Be sure to label the cables as they are installed.
