10 SIGNALING OPERATION
The DS21354/554 contains provisions for both processor based (i.e., software based) signaling bit access
and for hardware based access. Both the processor based access and the hardware based access can be
used simultaneously if necessary. The processor based signaling is covered in Section 10.1 and the
hardware based signaling is covered in Section 10.2. When referring to signaling, the Voice Channel
numbering scheme is used.
10.1 Processor Based Signaling
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 framer. Each of the 30 voice channels has four
signaling bits (A/B/C/D) associated with it. The numbers in parenthesis () are the voice channel
associated with a particular signaling bit. The voice channel numbers have been assigned as described in
the ITU documents. Please note that this is different than the channel numbering scheme (1 to 32) that is
used in the rest of the data sheet.
