RS1.2

Remote Alarm Bit (integrated and reported in SR1.6)

A(1)

RS2.7

Signaling Bit A for Channel 1

D(30)

RS16.0

Signaling Bit D for Channel 30

Each Receive Signaling Register (RS1 to RS16) reports
the incoming signaling from two timeslots. The bits in
the Receive Signaling Registers are updated on multi-
frame boundaries so the user can utilize the Receive
Multiframe Interrupt in the Receive Status Register 2
(SR2.7) to know when to retrieve the signaling bits. The
user has a full 2 ms to retrieve the signaling bits before
the data is lost. The RS registers are updated under all

conditions. Their validity should be qualified by check-
ing for synchronization at the CAS level. In CCS signal-
ing mode, RS1 to RS16 can also be used to extract
signaling information. Via the SR2.7 bit, the user will be
informed when the signaling registers have been loaded
with data. The user has 2 ms to retrieve the data before
it is lost.
