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
