Save money... operate analog equipment on digital CENTREX lines

The CTA-369, Centrex Terminal Adaptor, is designed to work exclusively with Northern Telecom's Meridian Digital Centrax offered from a DMS100 Central Office switch or an SL100 PBX. Connect the CTA to your Meridian Business Set (MBS) and operate any standard analog business equipment. You no longer need to rent a dedicated analog phone line to operate your answering machine, secure phone, modem, PC dialing program or credit card reader. Save money now by eliminating the need to rent dedicated analog phone lines.

The CTA come equipped with its own 24 VDC power supply and complete programming instructions. It features non volatile memory enabling it to retain its programming configuration even during power outages.

Application

Answering Machines
If you need to have an answering machine answer your phone lines when you are not there, use the CTA-369. Hook up the CTA between your telephone and your answering machine to make your answering machine work on the digital lines of the MBS telephone set. You can program the CTA to answer all the lines on your MBS or only those selected by you. This programming is done through the touch pad of your MBS phone. This combination also allows you to screen your calls and intercept calls even after the answering machine has answered.

Modems/Electronic Mail
Use the CTA-369 as an interface between your MBS and modem and you can connect a personal computer directly to any line on your MBS. The CTA-369 provides call privacy when you are “off hook”, this means your data transfer cannot be interrupted.

Auto dial
The auto dial mode allows a personal computer based auto dial program to dial the telephone number from the computer and then transfer the call to your Meridian Business Set.

Secure Phones/Speaker Phones
If you have an analog speaker/conference phone or a secure phone (like a STUIII), the CTA-369 will allow you to hook this equipment up to any line on your MBS.
