CCS
CAS-CC
CAS-BR
For CCS, CAS-CC, and CAS-BR, different types of support are provided.
Note: The internal HDLC- or CAS Controller supports all signaling procedures like
The next pages give a general description of the framing formats. After RESET, the
FALC54 must be programmed with FMR1.PMOD = 1.
Line Interfacing
• Ternary data with B8ZS or AMI(ZCS) coding (selection via bit FMR0.XC1/0+ RC1/0).
• Single rail unipolar data with no zero suppression algorithm (FMR0.XC1or RC1 = 0).
General Aspects of Synchronization
Synchronization status is reported via bit FRS0.LFA (Loss Of Frame Alignment).
Framing errors (pulse frame and multiframe) are counted by the Framing Error Counter
FEC.
Asynchronous state is reached if
2 out of 4 (bit FMR4.SSC1/0 = 00), or
2 out of 5 (bit FMR4.SSC1/0 = 01), or
2 out of 6 (bit FMR4.SSC1/0 = 10)
framing bits (terminal framing or multiframing) are incorrect. If auto-mode is enabled,
counting of framing errors is interrupted.
The resynchronization procedure can be controlled by either one of the following
procedure:
• Automatically (FMR4.AUTO = 1). Additionally, it may be triggered by the user by
• User controlled, exclusively, via above control bits in the non-auto-mode
Semiconductor Group
All code violations which do not correspond to zero code substitution rules are
registrated by the Code Violation Counter (CVC) with 16 bit length.
If AMI coding with zero code suppression (B7-stuffing) is selected, “clear channels”
without B7-stuffing can be defined by programming registers CCB1 … CCB3.
