Frame Alignment Word (FAW) Information.
The FAW section of page 3
provides channel Frame Alignment Word information for the communication
paths labeled CHL 1 and 2. For 2B calls, both CHL 1 and 2 are used. For
1-channel calls (112,bps, 128kbps, 168kbps, 196kbps, 224kbps, 256kbps,
280kbps, 320kbps, 336kbps, 384kbps, 768kbps, 1472kbps, 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 fields specific to endpoint-level command output.
A-OUT
MCU has endpoint framing.
A-IN
Endpoint has MCU framing
M-FRM
Multichannel frame alignment of both channels in 2B is present.
MFA
Multiframe alignment word is present (required in 2B call).
MFN
Multiframe numbering is present (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 endpoint FAW or multichannel synchronization
(M-FRM) to the endpoint. The MCU a-bit toggles when the MCU gains
or loses endpoint multichannel 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 detects in the endpoint’s a-bit (A-OUT). The
endpoint a-bit toggles when an endpoint gains or loses MCU framing.
This counter starts with 0x00, increments to 0xff, then wraps around to
0x01.
