Closed User Group (Cug) - Matrix ETERNITY NE System Manual

Closed User Group (CUG)

What's this?
A Closed User Group is a network of PBXs to provide seamless connectivity. The PBXs connected in the network
behave as a single unit. Extension users of one PBX can reach the extension users of the other PBX without dialing
any access code, as if they were dialing extension numbers of their own PBX.
You can connect ETERNITY NE and other PBX(s) to over Analog trunks as well as over the IP Network.

Here,
• ETERNITY is installed at Location A and is networked with PBX A at Location B.
• To create a CUG over Analog Trunks,
• the CO port of ETERNITY NE is connected to the SLT (FXS) port of PBX A.
• the CO port (FXO) of PBX A is connected to an SLT port of ETERNITY.
• To create a CUG over IP Network, both ETERNITY NE and PBX A may be connected directly to the
Public network, in Peer-to-Peer mode.
• The Extension Numbers of ETERNITY NE and PBX A must be unique.
• Seamless connectivity can be provided to the extension users at both locations with suitable configuration
of ETERNITY NE and PBX A.
