CALLER ID OPERATION

This product is designed to store and display information about incoming telephone calls. For this feature to work, the unit must be used with Caller Identification service provided by your local telephone company; there is a fee for this service, and it may not be available in all areas. This product can provide information only if both you and the caller are in areas offering Caller Identification service, and if both telephone companies use compatible equipment.

When you use this product with Caller ID service, you can see who’s calling before you answer the phone.

If you subscribe to Caller ID with Call Waiting, a combined service available through many local telephone companies, you can see who’s trying to reach you even when you’re on another call. This service may be called by different names (such as Caller ID with Visual Call Waiting) by different local telephone companies and may not be available in all areas.

NOTE: You must subscribe to combined Caller ID with Call Waiting as a single service on both lines to see Call Waiting information. Check with your local telephone company for availability.

This unit assigns each incoming call a number from 1 to 99. The most recent unreviewed call will have the highest number. (For example, if two calls have been received, call number 2 is the most recent.) When the call history is full, the oldest call information is automatically deleted to make room for the new incoming call information.

Incoming Number Announce

NOTE: Speaker volume must be set to a level you can hear for this feature to be effective.

In addition to the call information displays, this system can be set to announce the telephone number and line number (1 or 2) of incoming Caller ID calls. (See “Turn Incoming Number Announce On or Off” on page 19.)

If the incoming telephone number is connected to a Talking Caller ID Announcement, the system plays the Talking Caller ID Announcement instead of the telephone number.

The digital nature of the switch also facilitated easier integration with emerging technologies, paving the way for more advanced telecommunication services such as data transmission and multimedia communication.

Another characteristic of the AT&T 1782 switch was its reliability. The design emphasized redundancy and fault tolerance, which minimized downtime and improved service quality. This reliability made the switch suitable for various applications, from residential telephony to larger corporate communications.

The AT&T 1782 also supported advanced features like call routing, billing services, and maintenance monitoring. Service providers could implement these functionalities easily, allowing for personalized customer services and more efficient network management.

Overall, the AT&T 1782 embodies a critical advancement in telecommunication technology, providing the backbone for many service providers during a transformative time in the industry. Its combination of high capacity, digital processing, and reliability positioned it as a preferred choice for many communications networks, influencing how calls and data were managed for years to come.
