SLC-96 Format (SLC-96)
SLC framing mode allows synchronization to the SLC96 data link pattern. This pattern described in Bellcore
TR-TSY-000008, contains both signaling information and a framing pattern that overwrites the Fs bit of the SF
framer pattern. See
Table 13
.

1.
The SLC
96 frame format is similar to that of SF as shown in
Table 10
with the exceptions
shown in this table.
C1 to C11 are concentrator bit fields.
M1 to M3 are Maintenance bit fields.
A1 and A2 are alarm bit fields.
S1 to S4 are line switch bit fields.
The Fs bits in frames 46, 48 and 70 are spoiler bit switch are used to protect against false
multiframing.
