There is a slight echo. How can I adjust the sound quality?
First, verify that the Echo Cancellation option under the Port # menu of
T1/E1 Settings is enabled. If it is not, enable it. If echo persists, adjust the
RX Gain and TX Gain options on the same menu. For the gain options, it
is recommended to shift only between values of -5 and 5.
How is the loopback test useful for troubleshooting?
The loopback test verifies the integrity of the data being transmitted and
received on the T1/E1 port by sending a pattern out of the T1/E1 transfer
pins and expecting to see the same pattern come back on the receive pins.
This test requires that the T1/E1 port be disconnected from any external
device and a loopback connector be inserted to the port. A loopback
connector has pin 1 looped to pin 4, and pin 2 looped to pin 5.
