II. Configuring Related Parameters of R2 Signaling

R2 signaling conforms to ITU-T recommendation, and is classified into line signaling and register signaling, which can be used for national network and international network. China No. 1 signaling is a subset of R2 signaling. The line signaling, which is classified into forward and backward signaling, is mainly used to monitor the seizure, release and block state of the trunk. The register signaling, also classified into forward and backward signaling, adopts multi-frequency compelled mode to transmit address information, the language bit and authentication bit of international call, echo cancellation information, caller attribute and callee attribute information, and etc.

Please use cas-customcommand in E1 controller interface configuration mode and perform other configurations in R2 signaling configuration mode.
