  1. In the WebUI, click the Settings tab.
  2. In the left navigation pane, go to Signaling Groups.

To modify a Port:

Click the expand () Icon next to the entry you wish to modify.

Identification/Status - Field Definitions

The Identification/Status Panel controls the network identity of the port and its administrative state (Up or Down). It also provides the port's current service status and when that status last changed.

Port Alias

Specifies an alias for the port. This text is configured by the operator for exclusive use by SNMP-based element and network management systems to assign a key to the port or interface, that is unique across the managed network. Examples would be "Node10Port5" and "VerizonPort5"

Admin State

Specifies the administrative state of the port.

Physical Layer - Field Definitions

Analog Line Profile

Analog line profiles allow users to change the impedance presented by the Sonus SBC 1000/2000 FXS ports. It should match the impedance of the specified country's Telco. Some countries use resistive impedance and some use complex impedance. For example, telephone companies in the United States use 600 ohm resistive impedance where as Australia uses 220 ohms in series with the parallel combination of 820 ohms and 120 nF.

Relative Profile Adjustments

  • Negative values represent signal attenuation (lower volume).
  • Positive values represent signal amplification (higher volume).

Receive Gain

Allows you to control the gain or loss (in decibels) to the received voice levels.

Transmit Gain

Specifies the gain or loss in decibels to apply to the transmitted voice levels.

Receive and Transmit Gain affect FAX functionality. Use/Modify with care.
