MT128ISA/PCI
RVS-COM allows you to take full advantage of the CAPI API by providing for processes such
as sending and receiving faxes, receiving voice mail, using a full duplex sound card as a
telephone, transferring files from PC to PC, using terminal emulation for BBS and online
systems as well as accessing the Internet via ISDN.
NDIS
NDIS (Network Device Interface Specification) was developed by Microsoft and 3COM. It is
a Windows device driver interface that enables a single network interface card (NIC) to
support multiple network protocols. For example, with NDIS a single NIC can support both
TCP/IP and IPX connections. Certain ISDN adapters, such as the MT128ISA and
MT128PCI can also use NDIS.
NDIS includes a protocol manager that accepts requests from the network driver (at the
transport layer) and passes these requests to the NIC (at the data link layer), allowing
multiple NDIS-conforming network drivers to co-exist. In a situation where a computer
contains multiple NIC’s because it is connected to more than one network, NDIS can route
traffic to the correct card.
