Clock Synchronization
For E1:
Term: Provides an input that terminates the E1 signal.
Monitor: Provides high-input impedance and compensation for
resistive loss. This setting is useful for monitoring E1 signals at monitor
points, which are resistor-isolated.
Bridge: Provides high-input impedance for bridging lines that are
already terminated. This setting is useful for bridging directly across
copper cable pairs.
Line Coding: Allows the selection of the interface line coding. Line
Coding is not available with 2 MHz interface. Choices are:
For DS1: AMI and B8ZS. The default setting is B8ZS.
For E1: AMI and HDB3. The default setting is HDB3.
Framing: Allows the selection of the interface framing. Framing is not
available with 2 MHz interface. Choices are:
For DS1: SF, and ESF. The default setting is SF.
For E1: PCM30, PCM30 CRC-4, PCM31, and PCM31 CRC-4. The default
setting is PCM30.
