Connect to the PSTN Carrier
Once the Media Gateway is running, connect your PSTN interface or interfaces
to the carrier equipment. Use the standard cables specified for your card (refer
to the installation guide for that card).
Important On a T1/E1 card with multiple interfaces, the card uses the clock signal from
the first interface (Port 1) to support echo cancellation. If this interface does
not have an active T1/E1 circuit, the echo canceller uses a free-run clock that
is not synchronized with the other T1/E1 interfaces. The echo canceller might
not work properly, degrading the audio quality.
The interfaces on the cards are numbered from left to right. Therefore, to
ensure high audio quality, always connect the left interface first. If you want
multiple connections, you can then select any other interfaces.
Check Channel Status
Next check the channel status to verify that the PSTN circuits are up and ready
for calls. In the PSTN Configuration page, click Channel Status.
