Format
(in/out) The video format for single-screen c onferences: CIF, QCIF,
QCIF/CIF, H.CTS, H.CTX+, and SG4.
non-H.261 conferences = input and output formats are alwa ys
symmetric and the mode i s the same for input and output. (H.CTX,
H.CTX+ , and SG4).
H.261 mode non-continuous p resence conferences = symmetric
format (CIF and QCIF).
Non-presentation, continuous p resence conference in sing le-screen
= symmetric format (CIF and QCIF).
Presentation mode H.261 single screen c ontinuous presence cap able
conferences = sy mmetric input and outp ut formats QCIF/CIF
(displayed as CIF) or asymmetric QCIF/CIF, if the administered format
is upgradab le.
For quad-screen conferen ces = the format is QCIF/CIF to reflect the
QCIF input from all particip ants and output of CIF to all partic ipants.
For presentation mode quad -screen conference = the format is
QCIF/CIF to reflect the input/output of all pa rticipants except th e
presenter. In quad-sc reen mode, presenter input is always CIF.
FPS The CIF frame rate (frames per second) - ‘-‘, 30, 15, 10, 7.5. FPS
indicates the rate that endp oints can receive frames. The MCU cannot
detect maximum transmit frame rates or c urrent frame rates. Frame
rates change due to the amo unt of motion in the input image.
QFPS The ACIF frame rate (frames per second) (‘ - ‘, 30, 15, 10, 7.5). The
rate that an endpoint can g enerate/receive frames.
Quad-screen VAS conferences = QFPS reflects the highest common
QCIF frame rate of all endpoints and the vid eo mixer board rate, that
is lower than the rest of the particip ants. QCIF calculation acc ounts for
the highest common CIF frame rate declared by all conference
participants, sinc e the QCIF rate cannot be greater than that of the
highest common CIF rate.
Quad-screen presentati on conferences = QFPS reflects the highest
common QCIF frame rate of all particip ants and the video mixer board
rate. QFPS cannot be greater than the CIF frame rate that is
announced by the p resenter.
QFPS field is blank for proprietary modes.

This field defaults to n.
Type The type of conferee — Audio/Video (P64), Audio Add-on (AUD),
Cascade Link (CAS), BONDing Call (BOND), BONDing Cascade Link
(BCAS), UCC Controller (UCC), or Dedicated Access (DA). BONDing
calls use up to 12 chann els to form a single multimedia pip e.
Ext Administered endp oint extension. ( ).
