C.2.1 The DSH32-B Communications Module
The DSH32- B communications module is supplied as standard with some
packaged MicroVAX 3100 systems but it is available as an option to other
MicroVAX 3100 system configurations. The module, when used on its own,
provides eight asynchronous lines and one synchronous line. The model is
identified (defined) by the electrical interface of the synchronous line.
