Nortel Networks Modular ICS 4.0 manual Disconnect supervision, Hunt Groups, Internal numbers

192 / General System features

Disconnect supervision

When Disconnect Supervision is assigned to a line, the Norstar system monitors it to detect if an external caller hangs up. This allows the system to release the line for other uses. Your installer or customer service representative assigns disconnect supervision.

Hunt Groups

Your Norstar system now allows you to establish Hunt Groups in your system. Hunt Groups are a group of Norstar sets that can be called by a single directory number. The Hunt Groups feature ensures calls are easily routed to the appropriate people. For more information on Hunt Groups see “Programming Hunt Groups” on page 135.

Internal numbers

Each telephone in the Norstar system has its own internal number. The length of internal numbers in your system can be from two to seven digits on a non-expanded system, and three to seven digits on an expanded system. All numbers in your system are the same length. Your installer or customer service representative sets the length of internal numbers (called the DN length). The default DN length is three.

To find out your internal number, use the Button Inquiry feature ( ƒ•‚) on an intercom button. On the M7100 telephone, Button Inquiry shows your internal number followed by the function assigned to your single-memory button.

Line assignment

Any of the lines in your system can be assigned to any of your telephones. Your installer or customer service representative assigns lines to telephones in Configuration programming.
