1 GENERAL

ADC PatchSwitch Digital Patching with RS-232/V.24, X.21, and V.35 Switching equipment, hereinafter referred to as PatchSwitch or PS, provides convenient access to RS-232 (ANSI/EIA-

232)or CCITT V.24, X.21, or V.35 circuits for patching or switching to allow monitoring, testing, and reconfiguring of a communications network. The V.35 description is located in Section 3. The X.21 description is located in Section 4.

Note: The PatchSwitch equipment described in this manual conforms to EIA/CCITT (RS- 232/Recommendation V.24), interface between Data Terminal Equipment (DTE) and Data Communication Equipment (DCE) known as the Serial Binary Data Interchange or SBDI.

The PatchSwitch product line is a flexible, modular system providing the following features:

1.Monitoring of digital communications leads without circuit interruption;

2.Line access and switching on data communications circuit directed toward two (A/B) equipments at the DTE end and as directed toward the modem at the DCE end;

3.Loss of monitored signal alarming circuits which identify the down circuit with either or both visual and audible indications;

4.Optional signal monitoring and alarming of eight different RS-232 signal lines;

5.Optional interlocking in groups of two to 16 modules with A/B switching;

6.Optional interlocking in groups of two to 16 chassis with A/B switching;

7.Optional test module with three (3) RS-232 female ports for convenient interface with compatible test equipment, with or without lead status monitoring LEDs (8-leads monitored);

8.Flexibility of the modular system approach allows the addition of chassis and modules and the interchange of modules on a single line basis;

9.Module replacement or removal with no need for rear cable disconnection;

10.All female DTE and DCE connectors or female DTE and male DCE connectors;

11.High density chassis occupies 7 inches (17.78 cm) in height within a standard 19-inch (48.26 cm) wide rack;
