Manager: Small Community Networking

The IP Office systems within a Small Community network should only be connected using IP lines configured in a star and or serial layout. For each IP Office there should only be one possible IP Line route to any other IP Office even if that route is via intermediate IP Offices.

The following are examples of supported star and serial layouts. Note that the maximum number of hops for user information transfers is 5.

---- = IP network, | = IP Office IP Line.

The use of 'mesh' layouts connections is not supported. A mesh layout is one where there is more than one possible IP Line route between any two IP Offices. The following are examples of mesh layouts.

SCN Signalling
IP Office SCN uses a signalling similar to RIP is order to update each other of there presence. This traffic can be seen in the IP Office Monitor application as AVRIP packets. This traffic is is sent to port 50795 on which each IP Office system listens. Each IP Office in the SCN transmits an  update every 30 seconds. Additionally BLF updates are transmitted when applicable up to a maximum of every 0.5 seconds.  Typically the volume is less than 1Kbps per IP Office system.
