Notes:

1. Version 1.3 of the Bus Processor Unit (BPU) chip is required for T1.

2. An MFR card is required for DID/DNIS if DTMF signaling is used. If DID/DNIS is provided through DP sig- naling, an MFR card is not required.

3. SCC-B with ROM 1.3 or later is required if the central office does not provide T1 dial tone.

4. Version 1.2 of the Cable Kit is required for T1.

•The T1 trunk card must be installed in the “EC/TRK” slot.

•The installer must provide a Channel Service Unit (CSU) that complies with FCC Part 15 and Part 68. The CSU is installed between the DBS and the public network. The CSU provides alarm, diagnostic, and monitoring functions, as well as network protection.

The CSU must be compatible with the framing format (SF or ESF) that is provided by the public network.

Maximums

•One T1 card can be installed per cabinet.

•The number of T1 cards that can be installed in double-cabinet systems depends on the sizes of the connected systems. Table 4-12 on page 4-15shows T1 maximums for double-cabinet systems.

Note: The DBS 72 + DBS 40 combination does not support T1.
