Modifying the System
ADDING AN OUTSIDE LINE
The MERLIN II communications system is designed so that you can make changes quickly and easily. If the system is not at full capacity, you can add an expansion carrier, additional outside lines or voice terminals, or more data equipment. Modular plugs on much of the system wiring and modular components make it easy to reorganize the MERLIN II system as the customer's needs change.
With Feature Modules 1 and 2, you cannot switch module locations nor rearrange the modules on the carriers without having to readminister the system. Refer to “Module Installation” on page
With Release 3, you can replace a module with one of the same type using
The most common system changes are adding outside lines, adding voice terminals, and moving voice terminals. Contact an equipment supplier to order additional voice terminals and system modules.

The MERLIN II system can accommodate up to 56 outside lines. To add lines to the system, do the following:
1Have the local telephone company add the outside line(s) and network interface.
2Refer to “Connecting Outside Lines to the Control Unit” on page
3At the control unit, determine if an installed line module has unused line jacks. If so, simply connect new lines to the unused line jacks.
