10. SIGNALING OPERATION
Processor based (i.e., software based) signaling access and hardware based access are available.
Processor based access and 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.
10.1 PROCESSOR BASED SIGNALING
The robbed–bit signaling bits embedded in the T1 stream can be extracted from the receive stream and
inserted into the transmit stream by each framer. There is a set of 12 registers for the receive side (RS1 to
RS12) and 12 registers on the transmit side (TS1 to TS12). The signaling registers are detailed below.
The CCR1.5 bit is used to control the robbed signaling bits as they appear at RSER. If CCR1.5 is set to
zero, then the robbed signaling bits will appear at the RSER pin in their proper position as they are
received. If CCR1.5 is set to a one, then the robbed signaling bit positions will be forced to a one at
RSER. If hardware based signaling is being used, then CCR1.5 must be set to zero.
