DS1 Connections
General
NOTE:
Up to 28 optional DS1 connections can be made from the ARM shelf to the
office DSX for cross connections to customer DS1s.
NOTE:
To meet FCC EMC requirements it is required that there be a minimum of
30 feet of cable between the DSX and the SLC -2000 ARM shelf DS1 out-
put.
NOTE:
The maximum cable length to the DSX is 450 feet using 26 gauge wire
[ED7C723-37 Groups 1() to 3()] and 655 feet using 24 gauge wire.
NOTE:
Transmit (OUT) and Receive (IN) directions are run in separate cables to
the DSX. The cable shields shall not be grounded at the DSX and the
Transmit and Receive cables shall not be mixed on the same cross-con-
nect block.
NOTE:
DS1 Distribution (connectors J165-J168 on the ARM shelf backplane) is
associated with the “C” SONET multiplexer group and the DS1 (LS-C) cir-
cuit pack slots.
NOTE:
DS1 Feeder interface (connectors J160-J163 on the ARM shelf backplane)
is associated with the “A” SONET multiplexer group and the LIU (LS-A) cir-
cuit pack slots.
NOTE:
The SLC -2000 System supports either DS1 Distribution or DS1 Feeder, but
not both simultaneously. The same cable assemblies [ED7C723-37
Groups 1() to 3()] are utilized for either the A or C SONET multiplexer func-
tion group and can be moved to the associated connectors on the ARM
backplane for their appropriate application.
