Configuration Options
The default LADS Timing source has changed, affecting Table A-1 in
Appendix A.
Table A-1. System Options
LADS Timing
Possible Settings: Internal, External, Receive
Default Setting: Internal
Determines the timing source for the unit.
LADS Timing option appears when Operating Mode is set to LADS.
Internal – Timing is derived from the unit’s local clock. Use this setting for the LADS
primary timing unit that establishes the timing for both point-to-point units.
External – Timing is derived from the external clock provided by the DTE connected to
the V.35 interface on circuit CT113 (pins U, W).
NOTE: The valid rate generated by the DTE must be equal to the LADS line rate
minus the configured rate of 1600, 4000, or 8000 bps for the IMC, if
enabled.
Receive – Timing is derived from the line receive signal unless the unit is running
diagnostic tests. During the tests, the timing source is the internal clock. This setting
should be used for a LADS secondary timing unit.
