Adding a POTS IP SPC

Adding a POTS IP SPC

A semi-permanent connection (SPC) exclusively occupies a voice channel to meet the communication requirements and to ensure the communication quality for particular and vital access subscribers. To configure an IP SPC, configure the data to set up a direct IP connection between the two ends of the VoIP service. In this manner, the voice media data can be directly transmitted to the peer end.

Prerequisites

  • The electrical switch is already switched to the VoIP daughter board.
  • The IP address of the VLAN interface is already configured.
  • The remote VLAN interface can be routed and reached from the local VLAN interface.

Application Scenario

Figure 1-175 shows a sample network of the IP SPC service.
Figure 1-175 Network diagram of the IP SPC service

Procedure

  1. Run the voip command to enter the VoIP mode.
  2. Run the ip address command to configure the VoIP address pools.
  3. Run the quit command to quit the VoIP mode.
  4. Run the spc command to enter the SPC mode.
  5. Run the ipspc add command to add an SPC.

Example

To add a POTS IP SPC, do as follows:

NOTE:
The channel ID for a PSTN subscriber must be 0.
