Administering a Changed System

RENUMBERING AFTER REPLACING OR ADDING

MODULES

Performing system administration on an existing system that has been changed involves some special considerations. Read the following information carefully before you install or remove modules or change the basic settings for a MERLIN II system that is already in use. You may delete important system administration settings if you:

•Install or remove modules in the control unit

•Change the system size (small or large) or type (square, pooled, or behind-switch)

•Change a standard voice terminal setting to an attendant position setting or vice versa

If you replace a module with one of a different type, you must readminister the system to reassign numbers to lines and stations. The procedure for renumbering the system appears below.

NOTE: Replacing station modules may require readministration of features that are related to particular types of stations. For example, you might replace an analog station module that contained jacks used for attendant positions with a digital station module. Since digital voice terminals can’t be attendant positions, you would need to reassign those attendant positions to analog station jacks on a different module.

If you add modules without changing the modules that are already in place, the system assigns numbers to the additional lines and/or stations automatically. In that case, the numbers for the lines and stations that you‘ve already administered don‘t change, so you don‘t need to perform the renumbering procedure. (If you expand the system, be sure not to leave any empty slots between modules.)
