DESCRIPTION
X.21, or generally 56kbit/s for V.35.
For direct fiber connection between relays, 64kbit/s will offer slightly faster data transmission.
The setting is invisible when IEEE C37.94 Comm Mode is selected.
Baud Rate Ch2 20 12 64kbits/s
64kbits/s
56kbits/s
[Indexed String]
Channel 2 data rate setting for signalling between ends. The setting will depend on the MUX electrical interface, set 64kbit/s for G.703 and
X.21, or generally 56kbit/s for V.35.
For direct fiber connection between relays, 64kbit/s will offer slightly faster data transmission.
The setting is invisible when IEEE C37.94 Comm Mode is selected.
Clock Source Ch1 20 13 Internal
Internal
External
[Indexed String]
Setting that defines which clock source is used to synchronize data transmissions over channel 1. The setting will depend on
communications configuration and external clock source availability. If relays are connected direct fiber over channel 1, ‘Internal’ setting
should be selected. If channel 1 is routed via a multiplexer, either setting may be required (see Application Notes).
Clock Source Ch2 20 14 Internal
Internal
External
[Indexed String]
Setting that matches the clock source being used for data synchronization over channel 2.

Setting for channel 1 when connected to MUX. When set to ‘Auto’ P54x will configure itself to match the multiplexer.
The setting is visible only when IEEE C37.94 Comm Mode is selected.

Comm Fail Timer 20 18 10
From 0.1 to 600 in steps of 0.1
[Courier Number (time-seconds)]
Time delay after which the ‘Channel Fail Alarm’ will be issued providing that no messages were received during the ‘Channel Timeout’ period
or the ‘Alarm Level’ is exceeded.
Comm Fail Mode 20 19 Ch 1 or 2 Fail
Ch 1 Failure
Ch 2 Failure
Ch 1 or 2 Fail
Ch 1 and 2 Fail
[Indexed String]
Fail mode setting that triggers the ‘Channel Fail Alarm’, providing that the Dual Redundancy or 3 ended scheme is set.
