Signaling and Protocols
Table 2 lists the signaling and protocols supported by the unified gateway.
Table 2 Signaling and protocols
Signaling/Protocol |
Function |
SS7 |
Enables the communication between the unified gateway and switches supporting the SS7 signaling and enables the unified gateway to access E1 trunks provided by the switches. |
PRA |
Enables the communication between the unified gateway and the switches on the ISDN and enables the unified gateway to access E1/T1 trunks provided by the switches on the ISDN. |
R2 |
Enables the communication between the unified gateway and traditional switching devices and enables the unified gateway to access E1 trunks provided by the traditional switching devices. |
QSIG |
Enables the communication between the unified gateway and switches supporting the QSIG signaling and enables the unified gateway to access E1/T1 trunks provided by the switches. |
SIP |
Enables the interconnections between unified gateways and connects the unified gateway to IADs and SIP multimedia packet terminals. |
AT0 |
Connects the PSTN and switches. It is a DC loop analog trunk (also called narrowband trunk) and enables intra-office users to have voice communications with outer-office users through the obtained traditional phone lines, achieving easy narrowband access. |
SSH |
Secures remote logins to operation and maintenance terminal through an unreliable network to the unified gateway for configuration and debugging. |
SNTP |
Allows unified gateways to provide the time synchronization service for the client (IP terminal and SoftConsole server). |
SNMP v3 |
Simple Network Management Protocol, used for unified gateway alarm reporting. |
