Additional T1 Outputs

(990-72050-02 System Only)

Connect up to eight optional T1 outputs at the OPTIONS I/O wirewrap pins. See Figure 26 for the connector location, and Figure 30 for the connections.

Note: The shield pin is capacitively coupled to ground, therefore, the shield must be connected at the source end. The shield may also be connected at the TimeSource 3500 end for additional longitudinal noise protection.

Procedure F. IRIG-B TOD Output Installation

Step Procedure

1 Position the IRIG-B adapter onto the rear of the shelf so that the OPTIONS I/O wire-wrap pins project through holes in the adapter card.

2 Secure the adapter onto the shelf, using the four screws integral to the adapter

(see Figure 31).

3 To prevent small radius turns in the IRIG-B TOD output cables, secure the provided right-angle BNC connectors to the adapter BNC connectors, to direct the cables from the shelf as desired.

4 Connect the IRIG-B TOD outputs from the BNC connectors on the IRIG-B adapter to network elements requiring IRIG-B TOD timing.
