Using System-To-System Networking
The system-to-system networking feature allows the operating features that are discussed in the paragraphs
included in this section:
•
conferencing,
•
intercom calling,
•
call forwarding,
•
RNA, DND, and busy station call back,
•
message waiting lights,
•
call transfer.
An intregral part of system-to-system networking action involves the use of the channel resources between the
hub and the node systems. For example, should users transfer a call from node A to node B, then transfer it again
from node B to node C, and finally transfer it a third time from node C back to node A, channels between all three
nodes are employed. A feature of the networking software allows the system to rememeber from where the
transferred call originated and free all of the un-needed channels when the call gets transferred back to the
originating node. This channel freeing action is known as Release Link Transfer.
Release Link Transfer applies to any intra-node or inter-node call handling situation that leaves unnecessary
channels in its wake: such as: supervised and unsupervised transfer, call forwarding,and line pooling calls that
traverse multiple nodes.
Release Link Transfer applies to call handling situations that involve one node to the hub, multiple nodes to the
hub, one node to another node, and multiple nodes to multiple nodes.
NOTE: Release Link Transfer is not intended for certralized attendant service, which is not supported by the
system-to-system networking feature.
