2. Overview

The TL500A can be easily tailored to fit the needs of individual organizations or departments. A wide variety of remote site information systems can be accessed, and with its register programs, the system functions can be configured to meet the specifications of both calling and receiving modems and long distance switching time. By using programmable security codes (up to seven digits),

35 million possible combinations of codes prevent unauthorized access to the data devices.

The TL500A's routing function is based on DTMF tone detection. When a call is placed to the remote location, the TL500A detects the phone company's ringing voltage, goes off hook (answers), and begins a preliminary screening process.

During this time, the TL500A is looking for CNG and DTMF tone-based routing instructions. For instance, if the TL500A hears the industry standard CNG tone generated by a calling fax, the call is immediately and automatically routed to the connected fax machine without disturbing the receiving party, ringing attached phones, or

ringing other attached devices.

Each device port of the TL500A has its own DTMF security code that can be used to protect any devices connected to the ports from unauthorized access. Each separate security code can be programmed to any number up to seven digits, including the * and # characters found on the telephone key pad. During an incoming call, if the TL500A detects the DTMF access code for a device port, the call is automatically routed to the correct device.

In the absence of fax tones or security codes, the TL500A begins to ring the call through to its default port (Device 1).

Outgoing calls can be placed from any device port as if it were attached to a dedicated line. Only one device at a time can actively use the telephone line. When the line is in use by one device, other devices attempting to access the line for an outgoing call will receive a busy signal. With special programming, this feature can be overridden in an emergency situation where an outgoing call must be placed quickly. (Reference Register 07 & 08 on page 11).
