To modify a Port:
Modify FXO Port
The SBC 1000 supports fax on all TDM interfaces (PRI, BRI, FXS, and FXO). TDM calls, which have both call legs as TDM, use T.30 protocol. If either one or both of the call legs are IP (SIP), then the calls use T.30 protocol or inband audio. The SBC 1000 supports both the G3 and Super G3 fax protocols.
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
Selection of an Analog Line Profile enables you to change the impedance presented by the
Select a country from the drop down list. If the desired country or a similar country is not listed, select Other or Other European (TBR 21).
For FXO ports. The FXO ports MUST be calibrated to avoid audible echos on the line, reduced call quality, and Caller ID failure. See Calibrating FXO Ports,
Relative Profile Adjustments
- Negative values represent signal attenuation (lower volume).
- Positive values represent signal amplification (higher volume).
Receive Gain
Specifies the number of decibels to boost or attenuate the level of signal coming into the SBC on an FXO port. The default value of 6 dB compensates for the loss on an FXO line coming in from the local PSTN.
Increasing the receive gain could result in failure of caller ID and dtmf detection by the SBC.
Valid range: -10 to +10. Default value: +6.
Transmit Gain
Specifies the number of decibels to boost or attenuate the level of the signal leaving the SBC on an FXO port. An unnecessary change in the signal level could cause call failures.
Valid range: -10 to +10. Default value: 0
Ring Validation
Enables and disables ring validation by the FXO analog port.
Maximum Ring Frequency
Specifies the upper frequency limit used for ring validation by analog FXO port.
Minimum Ring Frequency
Specifies the lower frequency limit used for ring validation by analog FXO port.
Ring Detection Threshold
Specifies the RMS ring voltage, above which ring detection is guaranteed.
