STATUS INDICATOR DESCRIPTIONS
LSD
This interrupt indicates that the far-end of the line
is attempting to Activate the interface. May be
used as an alternative to the LSD pin to “wake-up”
a microprocessor.
AP
If set, indicates that either INFO 1 frames have
been identified in an NT receiver, or INFO 2 or
INFO 4 frames have been identified in a TE re-
ceiver. Requires an AR control instruction to allow
Activation to be completed.
This interrupt occurs when the closing flag of a
D-channel message has been transmitted by a TE
on the S interface, indicating successful comple-
tion of a packet. The Interrupt associated with this
bit can be disabled via the Control Register if de-
sired.
This interrupt occurs when, during transmission of
