Connecting Telephones Together
The Model 1040 series Central Office Simulators have two independent lines which can be used to place calls from one line to the other. These two lines work identically. Each can perform a wide variety of test functions as well as act like a normal telephone line. When you pick up a telephone connected to either line you will hear a dial tone. For your convenience, a single "5" will ring the other line at once. Unless reserved for a test function, most "regular" numbers will also cause the other line to ring.
Several more commands used with the Model 1040 series are descibed below.
A convenient way to use the Model 1040 is to have a control telephone (one which you know is functional) plugged into jack 1, and to use jack 2 to plug in the device you wish to test.
The following are some commonly used commands of the Model 1040 Central Office Simulator:
The Model 1040 Has Many More Features
For full information an all the varied features of the Model 1040 series Central Office Simulators, please consider purchasing the full manual. It is available at a nominal cost. There are at least 25 more functions that are fully described in the manual. For example, our Model 1040E features Caller ID origination for testing products that display Caller ID information.
In addition to describing test functions, the manual details how you can alter nearly every timing option (ringing cadence, for example) and frequency of tone that the Model 1040 produces by entering special commands on a connected telephone's keypad.
Another advanced feature of interest that both the Model 1040C and 1040E allow is interfacing to a computer via the serial port. Any terminal program on the host computer can be used; no specialized software is needed. Fully described in the manual, this allows you to monitor, test, and change a wide variety of parameters inside the Model 1040C or Model 1040E operating environment by using ASCII commands. It is even possible to download your own program code into the unit. This way you can give the unit capabilities for your specific testing situation or even give the unit abilities unrelated to its primary function as a Central Office Simulator.
