Use
DB15 socket. Provides the connection to your T1
DSX-1 (DTE).
50-pin RJ48H plug. Provides the connection to the T1
network for all eight slots supported by the Auxiliary
Backplane.
DB9 socket. Attaches an external clock. The external
clock provides timing for up to eight slots. Each
Auxiliary Backplane must have its own external clock
input.
DB25 (EIA-530A) socket. Provides the connection from
a 3161 DSU/CSU to the synchronous data DTE.
The Port 2 DB25 socket connector allows one slot in
the carrier to be configured as the COM port, which
replaces the functionality of the second data port. The
COM port is a communications port that provides
access to the front panel from a locally connected PC.
8-pin modular jack. Provides diagnostic connectivity
between Auxiliary Backplanes in a carrier.
