THE THREE TYPES OF CARTRIDGES

12. Type I Cartridges Give You Custom Features

Feature cartridges contain the software that enables you to customize your system. You have Feature Package 2, one of a family of feature cartridges designed for the Type I slot.

13. Type II Cartridges Give You Audio Options

Two different cartridges are available for this slot. One enables you to have Music- on-Hold. When this cartridge is connected to a music source, callers you put on hold will hear music. A second cartridge provides an interface for Music-on-Hold, back- ground music, and Loudspeaker Paging. When a loudspeaker paging system is connected to this cartridge, users can make announcements over it. For the paging system to work, set Paging Signal On/Off switch to On.

14. Type III Cartridges Give You Line-Associated Options

This cartridge supports two separate features: Power Failure Transfer and Extra Alert. Power Failure Transfer provides jacks for two basic Touch-Tone or rotary telephones. In case of a commercial power failure, with the Power Failure Transfer feature, telephone service is automatically switched to the backup phones. The Extra Alert jack enables you to connect a loud bell or horn for noisy or remote locations where the regular telephone ring can’t be heard.
