The next pages give a general description of the assigned framing formats. After
RESET, the FALC54 is switched into doubleframe format automatically.
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 FMR2.RFS1/0 for the receiver and FMR1.XFS for the transmitter.
Line Interfacing
• Dual rail data with AMI or HDB3 coding in conjunction with double violation detection
• Single rail unipolar data (FMR0.XC1/0) with NRZ or CMI Code.
• General Alarms
• AIS: Detection is flagged by bit FRS0.AIS. Transmission is enabled via bit
• LOS: Detection is flagged by bit FRS0.LOS.
• RAI: Remote Alarm Indication is flagged by bit FRS0.RRA and RSW.RRA.
• AUXP: Detection is flagged by bit FRS1.AUXP. Transmission is enabled via bit
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
In receive direction, 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 FALC54. Additionally, one transparent mode (XSP.TT0) can be
selected to achieve transparency for the complete time-slot 0. With the Transparent
Service Word Mask register (TSWM) the Si-bits, A-bit and the SA4-8 bits could be
selectively switched through transparently.
