June 2004
IP-Options Form Fields
The display system-parameters ip-options screen contains the following information:
•
IP Media Packet Performance Thresholds – used to determine the quality of the network
between various network regions and systems. If the network is judged to be of poor quality based
on these parameters, Communication Manager attempts to route calls via a different path (e.g.,
PSTN).
•
RTCP Monitor Server – a server that collects all RTCP information
•
IP DTMF Transmission Mode – indicates whether to send DTMF tones in band or out of band
•
H.248 Media Gateway Link Loss Delay Timer – the amount of time that a media gateway waits
before attempting to register with another controller after losing its link to the current controller. If
it regains a connection to the primary controller within that time, calls that were active when the
link was lost remain active.
•
H.323 IP Endpoint Link Loss Delay Timer – similar to the previous field
•
H.323 IP Endpoint Primary Search Timer – amount of time an H.323 endpoint should keep
trying to register with its primary controller before moving to an LSP
Administering the Media Gateway
Administering the Media Gateway requires you to administer the Primary Search Timer, the Total Search
Timer, and the MGC list Transition Point. You also administer an MGC list of up to four alternate
controllers for the gateway.
Administering the gateway timers and Transition Point
To administer the gateway timers and Transition Point
1
Administer the gateway’s Primary Search Timer (the length of time that the gateway spends
trying to connect to the primary server) by typing
set reset-times primary-search <search-
time>
at the Command Line Interface (CLI). The <search-time> values are
1-60
minutes.
NOTE:
The Primary Search Timer value should be shorter than both the Total Search Timer and
the Link Loss Delay Timer.
2
Save the configuration changes using the
copy running-config startup-config
command.
3
Administer the Total Search Timer (the length of time that the gateway spends trying to connect
to all alternate resources) by typing
set reset-times total-search <search-time> at the Command
Line Interface (CLI). The <search-time> values are
1-60
minutes.
NOTE:
The Total Search Timer value should be greater than the Primary Search Timer but shorter
than the Link Loss Delay Timer.
4
Establish the Transition Point (in either of the previous steps) by typing set reset-times
transition-point <n> , where <n> is the numbered element in the MGC list.
For example, if n= 2, the Transition Point is after the second element in the list. That is, the
gateway first attempts reconnecting with its original C-LAN circuit pack and then tries one other
alternate resource during the Primary Search Timer period. See
Table 23, Link Recovery Timers,
on page 61 for more information about the Link Recovery timers.
