3.2.8 Configuring Voice Port (ISDN PRI Interface)

Before entering voice port (ISDN PRI interface) configuration mode, first the ISDN PRI group needs to be created, so that the system will create the voice port corresponding to the PRI group automatically.

Please perform voice-port configuration in global configuration mode and perform other configurations in voice port configuration mode.

The default value of configuration command echo-cancel(enable echo cancellation) is enable, and echo-cancel coverage (the time coverage of echo cancellation sampling) 16ms, and input gain (voice input gain) 0, and output attenuation (voice output attenuation) 0.

3.3Monitoring and Maintenance of E1 Voice

I.Maintaining the MFC Channel and Circuit of the Specified TS

MFC channel is used to bear R2 register signaling, while the circuit is used to bear the actual incoming and outgoing calls. You can perform maintenance operations such as open, block and query to the MFC channel of the specified TS. You can perform operations such as open, block, query and reset to the trunk circuit of the specified TS. The operations of open and block are reverse process to each other.
