SONET APS Recovery Time Mode Disable - Channel n:
This READ/WRITE bit-field is used to either enable or dis-
able the "SONET APS Recovery Time" Mode within the Jit-
ter Attenuator, associated with Channel n.
If this feature is enabled the Jitter Attenuator (associated
with Channel n) will be configured such that the user's sys-
tem will be able to comply with the APS Recovery Time
requirements of 50ms (per Telcordia GR-253-CORE).
If this feature is disabled the System using the XRT75R03D
will NOT comply with the APS Recovery Time requirements
of 50ms.
NOTE: In this case, "APS Recovery Time" is defined as the
amount of time that will elapse between (a) the
instant that Automatic Protection Switching (APS) is
employed (either "automatically" or upon Software
Command), and (b) the instant that an entity (which
is responsible for acquiring and maintaining DS3/
E3 frame synchronization with the DS3/E3 data-
stream that has been de-mapped from SONET by
the Mapper device) has re-acquired DS3/E3 frame
synchronization, after the APS event.
0 - Enables the "SONET APS Recovery Time" Mode.
1 - Disables the "SONET APS Recovery Time" Mode.
