Appendix B
The TSU 600 chassis functions as a Remote Terminal in Digital Loop
Carrier and as Integrated Digital Loop Carrier Systems as described in
TR-TSY 000008. The TSU 600 supports SLC96 framing, Mode I opera-
tion, ORB-13 and ORB-16 alarm formats, alarm reporting, and user-de-
finable BPV threshold detection rate.
A basic familiarity with DLC systems, IDLC systems, and TR-TSY-
000008 is assumed, but the following information will be useful:
•
All received TR-TSY-000008 specific alarms are reported locally
within the history feature of the TSU 600.
•
When the DISABLE ALARMS option is selected, no alarms will be
sent on the DLF, but received alarms will be reported locally in the
history.
•
Other alarms normally reported by the TSU 600 will also be placed
in history.
•
Each TSU 600 needs to be configured as the A SHELF, as it is provi-
sioned as a separate entity.
•
All alarms will refer to A SHELF when received from TSU 600.
