Automatic Route Selection (ARS): Each node has its own ARS programming. All
trunk groups and nodes in a facility group must reside on the same node as the facility
group. You cannot place a node trunk group into a facility group. (See also Outgoing
Access on this page.) Using ARS is the only way a user can access trunks on other
nodes. If the system routes an outgoing call to another node using an intermediary node,
the intermediary node's ARS cannot use the nodes in its facility group to move the out-
going call to another node. This eliminates the system from getting into an infinite loop
searching for a node to route the outgoing call. (See
complete explanation of ARS.)
•
ARS Toll Restriction: When determining toll restriction for an ARS outgoing call, the
network only checks the station toll restriction for the node on which the station resides.
The system does not check the trunk class of service for ARS calls.
•
Emergency Calls: Emergency calls, by default, use the first local trunk group and will
not be sent using node trunk groups on other nodes. However, when ARS is used to
place an emergency call, Route Group 1 is used even if it contains nodes. This means
that the network can access a trunk on a node other than the user's node if the user
accesses ARS and dials the emergency number. Inter-Tel highly recommends that
local trunks be installed and used for emergency number trunk access and that nodes
not be used in Route Group 1. When a user places an emergency call, every adminis-
trator in the network receives an emergency alarm. (See
description.)
•
Direct Inward System Access (DISA): DISA callers can select off-node stations, hunt
groups, and Voice Processing applications.
•
Keymaps: Each node contains its own keymap programming.
•
DSS/BLF Keys: You can program a DSS button for an extension that resides on
another node. The buttons will show lamp status for stations on the other nodes.
•
Secondary Extension Keys: The primary station and the secondary station must reside
on the same node. (See
•
Music-On-Hold and Background Music: Each node has its own music source. If a
caller on Node 1 is holding for a user on Node 2, the caller hears the music on node 2.
Note that if a caller is holding for a user on Node 1 and the call moves to Node 2 (due
to a transfer, forward, or recall), the user will stop hearing the music on Node 1 and will
begin hearing the music on Node 2. (See
feature.)
NOTE:
caller hears based on the device for which the caller is waiting. See
details about how this affects music-on-hold in a networked system.
•
Handsfree Calls: The network allows handsfree intercom calls when calling from one
node to another.
Network Operation of System Features
®
INTER-TEL AXXESS
The network attempts to optimize routes so that calls do not route through a node
more than one time (looping). However, the network does not have the ability to
dynamically reroute. That is, if a node trunk group that was previously unavailable
becomes available after the network has already chosen another route, the network
does not reroute using that node trunk group.
The network will try to optimize routes when calls have been transferred or
reverse transferred across several nodes (possibly forming loops).
