PCM line bit rate
Single frame length
Framing frequency
Organization
time-slot 0 is reserved for frame alignment word and service information. Switching between the two
applicable framing formats (doubleframe/CRC-multiframe) is done via bit MODE.CRC.
Line Interfacing
General Alarms
Channel Assignment
The channel (time-slot) assignment from the PCM line to the system internal highway is performed
without any changes of channel numbering (TS0
the contents of time-slot 0 are switched through transparently. In transmit direction, contents of
time-slot 0 of the outgoing PCM frame are normally generated by the ACFA. Additionally, one of
three transparent modes (XSP.TT0S, XSP.TT0, EMOD.TT0X) can be selected to achieve
transparency either for S
Semiconductor Group
Dual rail data with HDB3 coding in conjunction with double violation detection or extended code
violation detection (CCR.EXTD). Errors can be counted by the Code Violation Counter CVC with
8- or 10-bit length (selectable via bit EMOD.ECVE).
Single rail unipolar data (MODE.OPT) with no zero suppression algorithm.
AIS: Detection is flaggered by bit RSR.AIS. Transmission is enabled via port COS or bit
MODE.XAIS.
NOS: Detection is flagged by bit RSR.NOS.
RAI: Remote Alarm Indication is flagged by bit RSR.RRA and RSW.RRA. Transmission is
enabled via bit XSW.XRA.
