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-custom
command in E1 controller interface configuration mode and
perform other configurations in R2 signaling configuration mode.
