PSTN connectivity testing
Use the PSTN Connectivity command to ensure that PSTN configuration is
correct. On initial installations, ensure that you have entered all required
information. On established installations, look for problems with the PSTN
connection. Use the command to indicate potential sources for problems.
Notes:
1.
When performing a PSTN connectivity test on a Remote Gateway 9150
unit, the test only checks the primary ISDN connection outbound from the
RLC. It does not check the primary connection inbound to the RLC from
the Remote Gateway 9150 unit's BRI circuit. The only way to verify an
initial primary PSTN connection from the Remote Gateway 9150 unit is to
manually initialize the primary link from the Remote Gateway 9150 unit.
PSTN connectivity tests always use the configured Trunk Support speed.
2.
When performing a PSTN connectivity test on a Remote Gateway 911x
series unit, the test only checks the primary PSTN connection to and from
the RLC.
To avoid common configuration mistakes, Nortel recommends that you test the
PSTN operation after you have finished configuring the PSTN numbers. In
addition, Nortel further recommends that you only do PSTN testing during
periods when the Remote Gateway 9100 Series unit is NOT in use.
PSTN connectivity tests work in two modes:
Disruptive mode
Note: If your Remote Gateway 911x series unit is operating in PSTN only
mode, you must perform PSTN connectivity testing in disruptive mode.
Non-disruptive mode
In both cases, you can perform the tests on a specified Remote Gateway 9100
Series unit for a specified range of data ports on the RLC. When using the
disruptive mode, Nortel recommends that you wait two or three minutes
between tests to give the Remote Gateway 9100 Series system time to recover.
