Chapter 4: Troubleshooting
The Gateway Series GUI password can be reset to its default without
modifying any configuration settings by following the steps described
below.
1. Press the reset switch once.
2. The status LED will start flashing amber.
3. Press the reset switch again while the status LED flashes amber.
4. The status LED will flash green for 2 seconds, acknowledging the
reset password request.
5. The password is set back to its default (i.e. “admin”).
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.
