Table 16-3 Manually Added System Flags – MCMS_PARAMETERS<br />

Flag and Value Description<br />

In H.239-enabled MIH Cascading, when MGC<br />

is on level 1, setting this flag to YES will adjust<br />

the line rate of HD Video Switching<br />

conferences run on the <strong>RMX</strong> <strong>2000</strong>/4000 from<br />

1920Kbps to 18432, 100bits/sec to match the<br />

actual rate of the IP Only HD Video Switching<br />

conference running on the MGC.<br />

Note: If the flag MIX_LINK_ENVIRONMENT<br />

is set to NO, the IP_LINK_ENVIRONMENT<br />

flag must be set to YES.<br />

The flag value determines how the ISDN Bchannels<br />

within configured spans are<br />

allocated.<br />

The robustness of the ISDN network can be<br />

improved by allocating channels evenly (load<br />

balancing) among the spans, minimizing the<br />

effect of channel loss resulting from the<br />

malfunction of a single span.<br />

Set the flag value to:<br />

• LOAD_BALANCE to allocate channels<br />

evenly among all configured spans.<br />

• FILL_FROM_FIRST_CONFIGURED_SPAN<br />

To allocate all channels on the first<br />

configured span before allocating<br />

channels on other spans.<br />

• FILL_FROM_LAST_CONFIGURED_SPAN<br />

To allocate all channels on the last<br />

configured span before allocating<br />

channels on other spans.<br />

Default: LOAD_BALANCE<br />
