3.2.6Configuring E1 Voice R2 Signaling

I.Configuring DS0 group

DS0 is the logical voice port abstracted from the actual E1 port by defining the time slot list, and it serves voice transmission. The time slots included in the DS0 group are all used to transmit voice, while the other time slots not included still can serve data information transmission. Only one DS0 can be defined on one E1 port. The R2 signaling configuration for E1 line is facilitated by configuring signaling type and the relevant parameters of R2 signaling for each DS0. When DS0 group is successfully configured, the system will create the voice port corresponding to the DS0 according to the current E1 port number and DS0 group number. The voice port number is “E1 port number: DS0 group number”.

For the commands in the table below, please use controller e1 in global configuration mode and the others in E1 controller interface configuration mode.
