Overview
System Renumbering (Flexible Numbering in the MERLIN II Communications
System) is the process of renumbering (reassigning) extension numbers to
stations, adjuncts, trunks, telephones, range of extensions on a DSS, Automatic
Route Selection, Calling Groups, Idle Line Access, Listed Directory Number,
Paging Groups, Park Zones, Pools, and Remote Access.
When the system is turned on, it identifies the type of module installed in each
slot in the control unit and automatically assigns extension numbers. When
assigning extension numbers, the system begins with the lowest-numbered slot
(with station jacks) and assigns numbers starting with the bottom (lowest) jack
and moving consecutively up to the top jack. The system then moves to the
next higher-numbered slot (with station jacks) and repeats the assigning
process.
The factory default extensions are assigned 2-digit extension numbers starting
with extension 10. If a user needs a specific extension number, it is simpler to
connect the user’s telephone to the station jack that is already assigned the
requested extension number than it is to renumber the jack where the telephone
is connected.
Both the number of digits and the extension numbers assigned by the system
can be changed to individually address a company’s needs. For example,
extension numbers can match room numbers.
Whenever extension numbers are renumbered, the following must be
considered:
■ Extension numbers can contain digits 0 through 9 in any combination,
except that no extension can begin with 0. Zero is a fixed extension
representing the primary system operator. The system can also be
programmed to associate 0 with a QCC operator position.
■ Extension numbers can contain one to four digits and must be unique. If
you renumber an extension number with one or two digits, you cannot
use those digits as the leading digits for a longer extension number. For
example, if extension numbers 1, 2, 30, and 40 are assigned to
telephones, those numbers cannot be used as the first number in longer
extension numbers such as 10, 200, 302, or 4052.
■ Whenever an extension number is renumbered, the original extension
number is available for use.
■ The reserved system-assigned extension numbers (shown in Figure 34,
Figure 35, and Figure 36) must be assigned a new extension number
before the original extension number can be used for anything else.
