IP Line Description, Installation and Maintenance
CHG ES1/CHG ES2
If the IP addresses entered for ES1 and ES2 are the same and both are not
0.0.0.0 or for external servers, an error message is generated and the input is
not accepted. Any value between 1000 and 60000 can be entered for the port.
If the port value is outside of that range, an error message is generated. Just
the port (and not the IP addresses) can also be configured. This is
accomplished by entering data similar to the following:
=>chg es1 0 5400
The value 0 for the IP address is interpreted as: 0.0.0.0. This means the Echo
Server runs locally using the configured port value.
The port values both default to 10000. If an IP address is configured, it is also
necessary to configure the port. An error message is generated if no port is
configured but an IP address is configured.
If both Echo Servers are not configured, then the LTPS on the Signaling
Server or the Voice Gateway Media Card uses two local instances of the Echo
Server. If both Echo Servers are configured, then the LTPS uses the external
Echo Servers. If an external Echo Server fails, that functionality is lost unless
the external Echo Server implements a transparent redundancy scheme. The
external Echo Server is responsible for its redundancy and reliability.
