MVME712A and MVME712AM transition cards
The MVME712A and MVME712AM cards provide four 9-pin connectors
(asynchronous serial ports 1Ð4) and a printer port connector. Additionally,
the MVME712AM card provides an RJ11 port.
The MVME712AM card (shown in Figure 21) has a built-in modem and is
used in countries in which that modem type is approved. The MVME712A
transition card, which does not provide a built-in modem, uses a locally
approved external modem for remote maintenance.
The built-in modem in the MVME712AM card provides full duplex
operation over two-wire Public Switch Telephone Networks (PSTNs). It
operates in asynchronous mode at data rates of 300, 600, 1200, or 2400 bps.
