As multi-service operations gradually become the major choice to enable corporate IT applications, carriers have provided their customers with optical network unit (ONU) modems that incorporate various interface services, including broadband internet access, corporate inter-connection, voice and network video, and more.
As a result, besides the network port for local maintenance and registration of IP terminals, a network port for audio equipment connecting to the ONU, is necessary, which should also be registered on the operator’s IMS platform.
The New Rock OM series IP PBX and MX series of VoIP gateways, both of which support dual network ports, can therefore meet the above requirements.
Network port 1: Connected to ONU. It is assigned to a dedicated IP address with an audio VLAN tag, and therefore directly registered with the operator’s IMS audio platform.
Network port 2: Connected to LAN. It is used for local maintenance and registration of local IP terminals, and also remote access to the device from external networks and network administrator systems.
·Audio quality is guaranteed and security risks are significantly minimized as audio service and data service are apportioned.
·Small call centers, mobile extensions, smart duty telephones, special line for VIP customers etc. will help operators improve their competitiveness and users’ loyalty.
· The number of audio users can be expanded by linking to IP-PBX without restructuring.If an enterprise already has a traditional telephone exchange (such as Nortel or Siemens), only SIP trunking can establish access to the operator’s IMS platform, but such systems (which have typically been used for 5-10 years) support only an ISDN 30B+D interface.
