Output Signals
The main shelf has 32 output connections arranged in four groups of eight outputs;
using the optional Expansion Panel, you can expand to 64 outputs. The outputs are
“universal,” and can supply E1, 2.048 MHz, T1, 8 kHz, CC, JCC, JCC4, 1.544 MHz,
and 6.312 MHz signals. E1 and T1 signals can be provisioned with standard framing
and G.703 formats. You provision the outputs in groups of eight outputs (or 16
outputs if the optional Expansion Panel is installed).
The TimeProvider use interchangeable Output modules, allowing you to select the
connector and termination impedance. Output modules are available with the
following connectors:
BNC – 75
DB9 – 120
Metric (Siemens) 1.6/5.6 – 75
Metric (Siemens) 1.0/2.3 – 75
Wirewrap – 100
BT43 – 75
Each Output module plugs into the shelf (and Expansion Panel) and provides
connectors and terminations for eight outputs. Make the output connections using
the procedures described in Making Output Connections, on page 60. You provision
the output signal type using the software commands described in Provisioning the
Outputs, on page 111.
