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 XRT75L03D
will NOT comply with the APS Recovery Time require-
ments 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.
