The recommended setting is the default

configuration. The rest of the configuration options

are meant for debugging or diagnosing issues in

the field.

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.
