Connecting Through a Channel Service Unit
DS1 Converter Connections for T1 Service -- Part 2 shows a typical connection for a T1 line, and DS1 Converter Connections for 120-ohm E1 Service -- Part 2 shows a typical connection for an E1 line.
- Connect the H600-348 Quad Cable to the DTE jacks on each of the 4 CSUs.
- You may need an adapter cable to connect the H600-348 cable to the CSU (see Adapter Descriptions).
- Connect one end of the H600-383 cable to the network jack on the CSU and the other end to the smart jack.
Connection to the remote-located system is the same as that shown in DS1 Converter Circuit Pack Switches and CAMA Numbering Format form.
Y Cable Lengths shows theY cable lengths.
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.
