Setting up REMS to provide re-sync to the encryptor

Provide re-sync leads to the encryptor as follows:

1. Connect the encryptor re-sync leads to the relay alarm contacts on

the back of the FBR CIM 2020. (Use the COM and NC terminals.)

Make the re-sync connections from the FBR to the KG at both ends

of the circuit. (See Fig ure5-4, Providing Re-sync Leads to the

Encryptor.)

Figure 5-4 Providing Re-sync Leads to the Encryptor

2. Put the testset in loop-timing mode.

3. Using the thumbwheel interface, set the re-sync timing on the FBR.

See Chapter 6,

Configuring and starting REMS

. Start with 6 seconds

(command 71). Timing may vary depending on the encryptor and the

type of transmission facility used.

4. If the circuit is not working as indicated by the REMS LEDs, the

problem maybe in the network. Verify the T1 line by plugging an

ASCII terminal into the Craft interface on the near-end BRC NCC

2020 front panel. (For details, see

AS2000 ASCII Terminal Interface
