Making Input Connections
The SSU-2000e Main shelf has nine sets of reference clock input connections on
DE9P male connectors for connecting input telecom signals. There are three
connectors in each set; each set is arranged vertically and labeled top to bottom
Monitor, Load, and Input, as shown in
with each input module, creating three groups for a total of 27 connectors.
Connections for group one are made in connectors J10 through J18, group two in
connectors J19 through J27, and group three in connectors J28 through J36. The
Load and Input connectors are cross-wired as four-wire east-west connections. The
Input connector is used for the reference input to the unit. The Load connector is
used for termination of the input in a two-wire input connection and is used as a
bridge or bypass connector in a four-wire or bridging connection. The Monitor
connector is connected as a 20 dB monitor to the reference input signal.
