Frame Alignment Word (FAW) Information. The FAW section of page 3
provides channel Frame Alignmen t Word information for the communication
paths labeled CHL 1 and 2. For 2B calls, both CHL 1 and 2 are us ed. For
1-channel calls (112,bp s, 128kbps, 168kb ps, 196kbps, 224kb ps, 256kbps ,
280kbps, 320kbp s, 336kbps, 384kbp s, 768kbps, 1472kb ps, 1536kbps, and
1920kbps) only CHL 1 is used. A-OUT, A-IN, M-FRM, MFA, and MFN are flags with
y or n.
Field descriptions
Page 4 - Endpoint Capability Information
This section describes fie lds specific to endpoint-level co mmand output.
A-OUT MCU has endpoint framing.
A-IN Endpoint has MCU framing
M-FRM Multichannel frame alignment of b oth channels in 2B is present.
MFA Multiframe alignment word is p resent (required in 2B c all).
MFN Multiframe numbering is pre sent (required in 2B call).
FAS Frame Alignment Signal (FAS) channel number (1 or 2). This number
should match the column header.
MCUFAL MCU Frame Alignment Loss (MCUFAL). Counts the number of times
the MCU reports lost endp oint FAW or multichannel synchronization
(M-FRM) to the endpoint. The MCU a-bit toggles whe n the MCU gains
or loses endpoint multic hannel synchronization. This counter starts with
0x00, increments to 0xff, then wraps around to 0x01. The MCUFAL
count also displays in the Fr Err field on Page 2
FEFAL Far End Frame Alignment Loss (FEFAL). Counts of the number of
changes the MCU detec ts in the endpoint’s a-b it (A-OUT). The
endpoint a-bit toggles when an endpoint gains or loses MCU framing.
This counter starts with 0x00, increments to 0xff, then wrap s around to
0x01.
