6-12 Compact T1 - Release 6.1
T1 Controller Card
TR-08 Mode 1
TR-08 Mode 1
The Compact T1 TR-08 will provide Mode 1 non-concentrated integrated service to the
Compact T1 platform. The TR-08/SLC-96 interface will allow a direct T1 physical
connection to a TR-08 capable digital switch, eliminating the need for an exchange
office end platform.
Each TR-08 provisioned T1 will handle the signaling throughput for 24 DS0 voice
channels. With T1-1 provisioned as an A shelf and T1-2 provisioned as a B shelf, the
Compact T1 will provide 48 DS0 voice channels with alarm reporting capability for
both shelves.
The TR-08 options can be provisioned either through CLI or controller front panel DIP
switches. When a T1 is provisioned to be TR-08, it’s respective set of service card slots
(T1-1 slots 1-3, T1-2 slots 4-6) will be nailed-up to the T1’s DS0s per TR-08 Mode 1.
Each T1 can be configured to be an A shelf or B shelf. The A shelf will carry alarm
information over FDL for the A and B shelf cards. The following combinations can be
set up:
l
Single A shelf
l
Two A shelves
l
A and B shelf
l
TR-08 provisioned T1 and a ESF provisioned T1
The A shelf can be set for FDL or no FDL and either alarm frame format 13 or 16 can
be selected. This selection can be done either by CLI (see set (ds1) in Chapter 5) or for
DIP switch settings (see DIP Switch Settings on page 6-9).
