AT11 Triple Port Expander

The Micro Seven-AT11 Triple Port Expander expands three lines for each real and simulated telephone lines, which include POTS and MINI-PBX SIMULATORs, model LS100, LS200, LS300, LS15, and PC300. An off-hook status from one of three devices that are connected to AT11 switches a telephone line to its own circuit if the other lines are not busy. Incoming call to AT11 will be connected to the last line that was used. The AT11 is operated with an AC adapter, 117 V. A 230V AC adapter may be ordered instead of 117V. The size of AT11 is small (4" x 1.75" x 7.5").

For example, 4-line, LS100-4 will expand the lines to 12 lines with four AT11s. A PC300-32, 32-line unit will expand the line to 96 lines thirty-two AT11s!

Another useful feature of AT11 is that any off-hook status from other two lines does not interfere current signal communication. For example, when one of three lines is connected to a telephone line and it is communicating via modem. Then, one person lifts a receiver at the other line, and tries to call, but the person will not receive any dial tone, and the person finds out that someone is using the line.

The price of AT11 is $115.00 plus shipping & handling. It is available from our stock.
