Frame Alignment Word (FAW) Information. The FAW section of page 3
provides the 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 (at rates of 112, 128, 168, 196, 224, 256, 280, 320, 336, 384, 768,
1472, 1536, and 1920 kbps), only CHL 1 is used.
A-OUT
,
A-IN
,
M-FRM
,
MFA
, and
MFN
are flags with values of
y
or
n
.
HYPR A value of
y
indicates hyperactivity from an endpoint (MCU isolated endpoint
from the MCU conference due to “thrashing” behavior) and affects endpoint’s
status as a video source (for 5 seconds of hyperactivity timer). The HYPR
counter indicates the number of times this endpoint was hyperactive.
DMUTE A value of
y
indicates that the decoder was muted by the VC board or the
software in the MCU. VC board mutes the decoder when it loses MMI or
endpoint framing is lost, when it receives an invalid audio code word, and when
endpoint is hyperactive. The only time that the MCU software mutes the
decoder of an endpoint is to mute every endpoint, other than the broadcaster,
when a mode of a conference is “broadcastw/scan” (broadcast with auto scan).
The DMUTE counter indicates the number of times this endpoint’s decoder was
muted by the VC board.
VFMT The video format applicable only to quad-screen conferences. This field
always has a value of n, indicating QCIF format.
H.261 A value of
y
indicates video framing loss. The H.261 counter indicates the
number of times the framing was lost.
A-OUT MCU has endpoint framing.
A-IN Endpoint has MCU framing
M-FRM Multichannel frame alignment is present (alignment of both channels in 2B).
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). A counter of the number of times the
MCU indicates to the endpoint that it has lost endpoint FAW or multichannel
synchronization (M-FRM). The MCU a-bit toggles when the MCU gains or loses
endpoint multichannel synchronization. This counter starts with an initial value of
0x00, increments to 0xff, then wraps around to 0x01. The MCUFAL count is also
shown in the
Fr Err
field on page 2.
FEFAL Far End Frame Alignment Loss (FEFAL). A counter 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 an initial value of
0x00, increments to 0xff, then wraps around to 0x01.
