Accessory Equipment

Once you have set up your MERLIN Plus system, you may decide to purchase additional hardware such as a headset that the system attendant can use for easier call-handling or a basic telephone that is connected to the MERLIN Plus system but which you can use off-premises. The information included in "Accessory Equipment" will help you decide what optional equipment you want to add to your system and how to use these accessories.

The information in the entry for each accessory is divided into five parts:

●Description

The description of the accessory tells what it does and its advantages for the user.

●Drawings and Diagrams

Drawings of the accessory and its parts are included for each piece of equipment, along with, if applicable, diagrams showing how the equipment is connected to other MERLIN Plus system accessories.

●Considerations

Special considerations include any qualifications the user should know about the hardware, ways in which the equipment can or cannot be used, or other hardware or features it can or cannot be used with.

●Administration

If applicable, administration procedures are given for setting options at the administrator/attendant console so that people in the MERLIN Plus system can use the accessory equipment.

●How to use

If applicable, procedures describe how to use the equipment or voice terminal .

Basic Telephones

DESCRIPTION	Basic Touch-Tone telephones can provide service to people at a remote
	location by way of an outside telephone line. These telephones are connected
	to the MERLIN Plus system by way of an Off-Premises Telephone Interface
	(OPTI) (see "Off-Premises Telephone Interface").
	The telephones can use many of the features of your on-premises
	communication system using dial codes and switchhook flashes.
