Integrated analog testing – Test and Heal
The analog trunk ports of the Branch Gateway are designed to meet certain standards.
However, loop characteristics such as signal loss, noise, and crosstalk can cause deviation
from those standards.
External testing of the loop typically involves removing the line from the Branch Gateway and
connecting it to measurement equipment, dialing into the Local Exchange Carrier's test facility,
and taking measurements locally. Alternatively, a technician can dial into a remote location
that terminates in additional measurement equipment.
The Branch Gateway's integrated analog testing feature provides a simpler procedure in which
the necessary testing is integrated into the Branch Gateway's analog ports, and the Branch
Gateway plays the role of the measurement equipment. Using CLI commands, you can:
• Dial out on a specific trunk port to measure noise, receive-loss, crosstalk, trans-hybrid
loss, or hybrid balance match
• Display the results of the measurements
• Take corrective action by manually setting a port's balance, receive-gain, or transmit-gain
The integrated analog testing feature enables quick and accurate testing of the loops at
installation, and custom modifications to the analog ports that require correction for the actual
loop characteristics. After installation, you can run additional tests whenever needed and
correct each port that requires tuning.

Description
Configure echo cancellation on the VoIP engine
The recommended setting is the default
configuration. The rest of the configuration options
are meant for debugging or diagnosing issues in
the field.
Control echo cancellation on the VoIP engine
The recommended setting is the default auto
mode. In this mode, the Media Gateway controller
consults internal rules to determine when to
employ the VoIP echo canceller for each call.
