1. Within the voice communication system, an AR can function as an IP PBX or SIP access

gateway(AG). The AR connects to POTS users (analog phones or fax machines) and SIP user

equipment (UE) users (IP phones or Video endpoint) through FXS or Ethernet interfaces.

2. Video endpoint can register with AR using SIP protocol.

3. The AR connects to the PSTN through FXO interfaces or trunking and to the IP network through

Ethernet interfaces.

• Video conference through MCU convening• Subscribers reserve a conference on ResourceManager and add participants. The video conference through MCU

convening can be triggered manually on RM or be initiated automatically at the scheduled starting time. PSTNusers can join a video conference through MCU convening.

• Anonymous access to a conference• If a conference doesn’t specify the subscriber numbers when being reserved on ResourceManager, subscribers

can dial the conference ID and password to join the video conference. PSTN users of SoftCo can join aconference in anonymous way.

100/1000BASE-TX

RJ-45 FE interface. Themaximum transmissiondistance is 100 meters.

It is used to connect to a LAN switch. In single network-port mode, the twonetwork ports work in active/standby mode. In two-network-port mode, network port 0 functions as the maintainingnetwork port and networkport 1 functions as the service network port. The two network ports areconnected to different LANs, thus separating service data from maintenance data.

Among the AR200 series routers, only the AR207Vs support the voice

features.

Among the AR1200 series routers, only the AR1220Vs and

AR1220VWs support the voice features.

The AR2200 and AR3200 series support the voice features only after

the DSP module is installed.

To provide voice services for POTS users on AR1200, AR2200 ,and

AR3200 series routers, 4FXS/1FXO board is required.
