Caller-ID Telephone Line Simulator

Party-Line is our six extension telephone central office (telco) simulator that is designed for both professional and personal use. It allows you to easily demonstrate all types of standard telephone equipment, including those supporting Caller-ID, Distinctive Ringing services, and Visual Message Waiting signal emulation.

Click for Bigger Party-Line Picture Telephone equipment will behave as if it were connected to a real telephone line. You will hear authentic North American dial tone, busy signals, and ringing. Even the most discriminating listener won't be able tell that this phone line simulator is not a real telephone line. Party-Line is perfect for use with call progress tone selective equipment such as modems and fax systems. Due to its exceptionally clear talk path, you can be assured of high quality voice transmissions as well as reliable high-speed data connections using PC modems.

North American Bellcore and Canadian Stentor Caller-ID signaling is provided in single message (number only) and multiple message (name and number) formats. One of six pre-programmed sample names can be sent and the displayed directory number is easily chosen when you make the call. Best of all, there are no PC connections or computer assisted programming necessary to configure the Caller-ID message formats.

Distinctive Ringing support allows you to assign a unique ring pattern (five are available) to a called telephone extension. This feature emulates the distinctive ringing feature that is currently offered in many parts of North America.

The Visual Message Waiting feature emulates both the stutter dial tone and FSK tone based signals. Many central office based voice mail systems now use this signal format and Party-Line offers a convenient way to show your customers how it works. You can easily test and demonstrate the message waiting lights used on many desktop boxes and single line feature phones.

Calling any of the six extensions is just like making a typical phone call. Just dial a local (seven digit) or long distance (eleven digit) phone number. You get to choose the number, except the last two digits are used to indicate the extension and distinctive ring pattern.

Unlike some telephone test equipment, Party-Line's 20 Hz ring generator uses digital precision to ensure that standard telephone equipment can be operated. The ring circuit uses a superimposed 90 VAC voltage source too, just like the phone company's, to maintain compatibility with popular telephone products. The 28VDC talk path voltage is current limited to prevent damage to sensitive equipment such as PCMCIA modem cards.
