8 SIGNALING OPERATION
The Channel Associated Signaling (CAS) bits embedded in the E1 stream can be extracted from the
receive stream and inserted into the transmit stream by the DS2153Q. Each of the 30 channels has four
signaling bits (A/B/C/D) associated with it. The numbers in parentheses are the channel associated with a
particular signaling bit. The channel numbers have been assigned as described in the ITU documents. For
example, channel 1 is associated with time slot 1 and channel 30 is associated with time slot 31. There is
a set of 16 registers for the receive side (RS1 to RS16) and 16 registers on the transmit side (TS1 to
TS16). The signaling registers are detailed below.

Each Receive Signaling Register (RS1 to RS16) reports the incoming signaling from two time slots. The
bits in the Receive Signaling Registers are updated on multiframe 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 2ms to retrieve the signaling bits before the data is lost. The RS
registers are updated under all conditions. Their validity should be qualified by checking for
synchronization at the CAS level. In CCS signaling 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 2ms to retrieve the data before it is lost.
