outside call, and the system has a DSP daughter board installed with the VRS
compact flash, the queued caller will hear, “Please hold on. All lines are busy. Your
call will be answered when a line becomes free.”
The VRS can also transfer calls to UCD (Department) groups . Refer to the Voice
Response System (VRS) on page 2-83 feature for more information on setting up the
VRS.
The system prevents hunting to a UCD (Department) group extension if it is:
J
Busy on a call
J
In Do Not Disturb
J
Call Forwarded
J
Logged Out
Uniform Numbering Network
Uniform Numbering Network allows multiple or compatible systems to be connected
in a network using Tie Lines. A station user can dial a system number and a station
number (open numbering) or dial the station number only (closed numbering) to
access any station. When the calling and called systems are not directly connected,
several Tie Lines may be accessed to route the call. Each system extends the call to
the next system until the final destination is reached. Networking provides a
seamless connection of multiple systems into a single “virtual” communications
system using Tie Lines with a unified numbering plan. Networking will allow many
companies to connect their telephone systems so they appear as one. An extension
user in the network can easily dial another extension or transfer a call within the
Networking System. Calls are passed from network node to network node using a
protocol that contains information about the source of the call, the type of call and the
destination of the call.
Flexible Network Routing
Use network routes to set up “single channel” networking between many separate
systems – or use multiple networking channels per system for greater network
performance. Data tables in the system program define the routing for each extension
in each network node. These tables are easily customized to meet the requirements
of each networking configuration. Users may place an intercom call or transfer a call
to any extension at any location by simply dialing an extension number. The system
analyzes each extension number received and determines how to route the call to its
final destination. The feature which handles this route selection is called Flexible
Routing (F-Routing). F-Routing also has the ability to select alternate routes to the
destination extension if the primary destination is busy. Up to 120 routes are available
for networking. Once an extension number is dialed, the system checks the routing,
