1 PRODUCT OFFERING
The ADC V.35 PatchSwitch makes available four modules, four conversion boards and the necessary
conversion patchcords for use with the 34-pin “V.35 Interface” data communications hardware.
The units are designed to be compatible with the RDC-01, RDC-02, PSC-01, and PSC-02
standard PatchSwitch chassis. The V.35 modules utilize grey front panels so they can be mixed
with other interfaces and still be identified a V.35 circuits. The modules provide monitor and
patch access in the Serial Binary Data Interchange (SBDI) portion of data communications
circuit. Some modules also provide local and remote alarming as well as signal status
indication. A more detailed description of each module is given in Table 3-1. The SBDI is
typically found between the MODEM (DCE) and the TERMINAL/COMPUTER (DTE). A
single circuit requires one module and one conversion board which connects between DTE-A or
DTE-B and DCE. Switching takes place between DTE-A and DTE-B to connect to DCE. As an
alternative to the V.35 conversion boards, V.35 cables using DB-25 connectors can be used to
attach easily to the RDC-01/PSC-01 and RDC-02/PSC-02 PatchSwitch chassis.
