DS1 Output Module
This section provides user-reference data for the DS1 Output module (part number
23413017-000-0) used in both the SSU-2000 main shelf and in the optional
SDU-2000 Expansion shelf.
Functional Overview
The DS1 Output module generates a phase-locked signal of 1.544 Mbps using one
of three 4 kHz clocks from the backplane of the SSU-2000 main shelf (A, B, and, C
clocks). If the module is inserted into the SDU-2000 Synchronization Distribution
Unit (expansion shelf), a fourth 4 kHz clock (D clock) is available. The phase-locked
signal generates a set of 20 output signals for distribution to large networks. A
simplified block diagram of the DS1 Output module is shown in Figure 8-3.
