Setting up external timing
This section describes how to provide external timing to the external input
of the BRC. The timing source must be the same one that provides CLK
to the rest of the equipment in the circuit. See Figur e5-5, External Timing
Block Diagram of Near-end and Table5- 1, REMS External Timing
Configuration.
“Master and Remote” configuration refer to the FBR only
Internal/external timing refer to the BRC only.
1. Set the Multiplexers to loop timing.
If loop timing is not possible, you can set the end Multiplexers for
external timing and use the same external timing source provided to
BRC EXT input or the RSC from the encryptor
Or,
2. Set the Multiplexers’ timing to external timing and connect the FBR
64 KHz reference, which is synchronized with RSC. (See Figur e5-5,
External Timing Block Diagram of Near-end.)
