System Configuration Flags
Polycom®, Inc. 802
TC_LATENCY_SIZE This flag limits the latency (in milliseconds) or the number of bytes that can
be present in a queue.
Range: 1-1000 (in milliseconds).
TCP_RETRANSMISSION_TIMEOU
T
The number of seconds the server will wait for a TCP client to answer a call
before closing the connection.
Default = 5 (seconds)
TRAFFIC_SHAPING_MTU_FACTO
R
Used for the MTU (Maximum transmitting Unit - the size of transmitted
packets) dynamic calculation:
New MTU = video bit rate / TRAFFIC_SHAPING_MTU_FACTOR
where the new MTU value is guaranteed to be a minimum of 410, and a
maximum of 1460 (MAX_MTU). The purpose of this calculation is to match
video rate in outgoing video to call rate, yet force lower encoder bit rates to
avoid overflow.
This flag is applicable only when traffic shaping is enabled (see
ENABLE_RTP_TRAFFIC_SHAPING).
Range: 0-5000, where 0 signifies no change in MTU
Default: 800
V35_MULTIPLE_SERVICES Not Supported in RMX 1800.
If the connection of multiple Serial Gateways to RTM-LAN cards is required:
The V35_MULTIPLE_SERVICES System Flag must be set to YES.
The default value of the V35_MULTIPLE_SERVICES System Flag is NO,
enabling only one Serial Gateway to be supported per RTM-LAN card.
V35_ULTRA_SECURED_SUPPOR
T
This flag must be set to YES when deploying a Serial Gateway S4GW in
Ultra Secure Mode.
VIDEO_BIT_RATE_REDUCTION_P
ERCENT
Indicates the percentage of actual reduction in bit rate sent from the RMX to
the endpoint (negotiated bit rate is not reduced). This flag is applicable only
when traffic shaping is enabled (see ENABLE_RTP_TRAFFIC_SHAPING).
Range: 0-60
Default: 15
VSW_CIF_HP_THRESHOLD_BITR
ATE
Controls the Minimum Threshold Line Rate (kbps) for CIF resolution for
High Profile-enabled VSW conferences.
Default: 64
VSW_HD_1080p_HP_THRESHOL
D_BITRATE
Controls the Minimum Threshold Line Rate (kbps) for HD1080p resolution
for High Profile-enabled VSW conferences.
Default: 1024
VSW_HD_720p30_HP_THRESHOL
D_BITRATE
Controls the Minimum Threshold Line Rate (kbps) for HD720p30 resolution
for High Profile-enabled VSW conferences.
Default: 512
