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 car d slots
(T1-1 slots 1-3, T1-2 slots 4-6) will be nailed-up to the T1’s DS0s per TR- 08 Mod e 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 shel f cards. The following combinations can be
set up:
lSingle A shelf
lTwo A shelves
lA and B shelf
lTR-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 ca n
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).
