Note
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.
Termination
This option determines whether or not the ISDN S/T interface is terminated on this port.
The BRI physical interface comprises two parts:
- in-house cabling (S/T bus) from the ISDN terminal to the Network Termination (NT).
- transmission from the NT to the Central Office (U-reference point).
An S/T bus must be terminated at both ends. One end of which is the Network Termination device and the other end is the Terminal Equipment (TE) end.
Common Connection and Termination Scenarios
| Connection Scheme | Termination |
|---|---|
| No other devices on the same S-Bus. | Enabled |
| Other devices on the same S-Bus and the SBC is not the last device on the bus. | Disabled |
| SBC is connected to a PBX. | Enabled |
Important Note
The BRI port on the SBC does not supply power.
