A.3 SLC 96 Format (SLC)
SLC framing mode allows synchronization to the SLC 96 data link pattern. This
pattern, described in the Bellcore TR-TSY-000008, contains both signaling
information and a framing pattern that overwrites the Fs bit of the SF framer
pattern. (See
Table A-3. SLC-96 Fs Bit Contents
Note(s):
1. The SLC-96 frame format is similar to that of SF as shown in
2. C1 to C11 are concentrator field bits.
3. M1 to M3 are maintenance field bits.
4. A1 and A2 are alarm field bits.
5. S1 to S4 are line switch field bits.
6. The Fs bits in frames 46, 48, and 70 are spoiler bits which are used to protect against
