DEFAULT

DESCRIPTION-OPERATION

Ch. 0

RUR

These bits indicate whether the Channel Associated signaling data,

associated with Time-Slots 0 through 7 within the incoming T1 data-

stream, has changed since the last read of this register, as depicted

below.

0 - CAS data (for Time-slots 0 through 7) has NOT changed since the

last read of this register.

1 - CAS data (for Time-slots 0 through 7) HAS changed since the last

read of this register.

NOTES: This register is only active if the incoming T1 data-stream is

using Channel Associated Signaling.
