In Release 6.0, calls arriving for extensions at one system cannot be covered by extensions or calling groups on a non-local system.
For Release 6.0 and later systems, non-local dial plan calls are treated as outside calls by the system and by Selective Coverage features: Coverage Inside and Coverage VMS Off.
In Release 6.1 and later, the Group Calling feature is enhanced to allow a calling group to have a single non-local member that is used to route calls to a remote system. A calling group containing a single non-local member can be used for many of the same purposes as a calling group containing only local extensions. This includes Group Coverage across a private network to a centralized VMS/AA, non-local calling group, QCC queue, DLC, or any individual extension on a remote MERLIN LEGEND, DEFINITY ECS or DEFINITY ProLogix system, or to the PSTN via UDP routing.
To ensure that VMS/AA calls transferred across the private network have time to go to coverage if not answered, it is recommended that group coverage ring delay for each sender be set to three rings or less.
Digital data calls between networked systems must travel over PRI tandem trunks or T1-emulated tie trunks programmed for data. 2B data is supported when two B-channels or T1 channels are available. UDP routes for digital data calls over tandem PRI trunks can specify voice and data or data only service. UDP routes for pools of T1-emulated tie facilities must specify data only. On tandem PRI facilities, 128-kbps 2B data speeds are supported. T1-emulated tie trunks programmed for data support 112-kbps 2B data speeds.
If you are using fractional point-to-point T1 facilities as tandem tie trunks, you can program some channels for data-only; remaining channels can be dedicated to voice only.
