TFDL7
TFDL.7
MSB of the FDL code to be transmitted.
TFDL0
TFDL.0
LSB of the FDL code to be transmitted.
The Transmit FDL Register (TFDL) contains the Facility Data Link (FDL) information that is to be
inserted on a byte basis into the outgoing T1 data stream. The LSB is transmitted first.
7.0 SIGNALING OPERATION
The robbed bit signaling bits in embedded in the T1 stream can be extracted from the receive stream and
inserted into the transmit stream by the DS2141A. 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 0,
then the robbed signaling bits will appear at RSER in their proper position as they are received. If
CCR1.5 is set to a 1, then the robbed signaling bit positions will be forced to a 1 at RSER.
