Switch Line Carrier - 96 (SLC-96) Format (T1 only)
made up of 6 SFs, but some F-bit are used as Concentrator Bits, Spoiler
Bits, Maintenance Bits, Alarm Bits and Switch Bits. Each frame consists
of one overhead bit (F-bit) and 24 8-bit channels. Its Frame Alignment
Pattern is ‘001000110111001000110111’ in 24 consecutive F-bit posi-

tions. If the Frame Alignment Pattern is found in 24 consecutive F-bit
positions in the data stream, the SLC-96 synchronization is acquired.
The first frame is numbered from the frame whose F-bit contains the first
‘1’ of the Frame Alignment Pattern.
RMFBI bit is set at the first bit of each SLC-96 frame.
Frame No.
The SLC-96 synchronization is indicated by ‘0’ in the OOFV bit. The
