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.
