These registers are used to configure the transmit interfaces of the S/UNI-MPH.
LCDEN:
The LCDEN bit enables the receive loss of cell delineation indication to
automatically generate a receive failure indication in the transmit stream.
This bit operates regardless of framer selected (T1 or E1). When LCDEN is
logic 1, declaration of the LCD alarm causes a yellow alarm (T1) or remote
alarm indication (E1) to be transmitted for the duration of the LCD alarm.
When LCDEN is logic 0, assertion of the LCD alarm does not cause
transmission of a receive failure indication.
AISEN:
The AISEN bit enables the alarm indication signal carrier failure alarm to
automatically generate a receive failure indication in the transmit stream.
This bit operates regardless of framer selected (T1 or E1). When AISEN is
logic 1, declaration of the AIS CFA causes a yellow alarm (T1) or remote
alarm indication (E1) to be transmitted for the duration of the CFA. When
AISEN is logic 0, assertion of AIS CFA does not cause transmission of a
receive failure indication.
REDEN:
The REDEN bit enables the red carrier failure alarm (persistent out of frame)
indication to automatically generate a receive failure indication in the transmit
stream. This bit operates regardless of the format selected (T1 or E1)
When REDEN is logic 1, declaration of the red CFA causes a yellow alarm
(T1) or remote alarm indication (E1) to be transmitted for the duration of the
