8.3 Multiframes Out Of Sync Count Register (MOSCR)
Normally the MOSCR is used to count the number of multiframes that the receive synchronizer is out of
sync (RCR2.0=1). This number is useful in ESF applications needing to measure the parameters Loss Of
Frame Count (LOFC) and ESF Error Events as described in AT&T publication TR54016. When the
MOSCR is operated in this mode, it is not disabled during receive loss of synchronization (RLOS=1)
conditions. The MOSCR has alternate operating mode whereby it will count either errors in the Ft
framing pattern (in the D4 mode) or errors in the FPS framing pattern (in the ESF mode). When the
MOSCR is operated in this mode, it is disabled during receive loss of synchronization (RLOS = 1)
conditions. See Table 8-3 for a detailed description of what the MOSCR is capable of counting.

NAME AND DESCRIPTION
MOS/FB11
MOSCR1.7
MSB of the 12–Bit Multiframes Out of Sync or F–Bit Error Count (note #2)
MOS/FB0
MOSCR2.0
LSB of the 12–Bit Multiframes Out of Sync or F–Bit Error Count (note #2)
NOTES:
1. The lower nibble of the counter at address 25 is used by the Path Code Violation Count Register
2. MOSCR counts either errors in framing bit position (RCR2.0=0) or the number of multiframes out of sync (RCR2.0=1)
