3.1. 2-Port Multiprotocol PCI Adapter (DCCG140)
The
2-Port Multiprotocol PCI Adapter
allows connections between stand alone systems on a Wide
Area Network (WAN). To access WAN lines, the 2-port Multiprotocol PCI Adapter connects via
external communications equipment including Channel Service Units, Data Service Units and
Synchronous Modems.
The
2-Port Multiprotocol PCI Adapter
consists of a card that supports 2 ports with either V.24 or
V.35 or V.11/X.21 physical interface. Each port can run either SDLC or X.25.
TCP/IP, Communication Server
applications run and have access to X.25 networks through this
adapter.
Communication Server
applications run and have access to SDLC networks through this adapter.

Cables
Each port accepts a high-density 36-pin male cable connector. The types of connector used on the
interface-specific end of cable are:
Interface Connector
V.35 Type M
V.24 DB25
X.21 DB15
The 2-Port Multiprotocol PCI Adapter recognizes the cable and automatically prepares the port for that
interface.
Attachment
The controller fits into a single short PCI adapter slot.
