What type of cable do I need for the T1/E1 ports on a Gateway Series
appliance?
A straight-through RJ45 T1/E1 cable is needed for connecting to the RJ45
ports on a Gateway Series appliance when connecting to the PSTN. If
connecting to a TDM PBX, a crossover RJ45 T1/E1 cable may be
required. The appropriate cables may be ordered from Digium by visiting
www.digium.com. Refer to Table A-2 on page 60 for pin assignments.
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.
