Japanese Sine Wave Output Module

This section describes the Japanese Sine Wave Output module (part number
23413304-000-0). It provides details on operation, configuration, provisioning
settings, and specifications.

Functional Overview

The Output module uses one of three 4 kHz clocks from the SSU-2000 main
chassis backplane to generate a phase-locked reference signal for the
synchronized clock output signals. If the unit is inserted into an SDU-2000
expansion shelf, a fourth 4 kHz clock (D-clock) is available. The phase-locked signal
is used to generate 20 software selectable outputs of either 6.312 MHz or
1.544 MHz for distribution to large networks.
The 20 sets of signal pairs, TTIP and TRING, represent a transformer-coupled
symmetrical pair. Each output can be turned on/off independently of other channels.
Each output signal is monitored for a failed output on an independent basis.
