Overview
This guide describes how to install and configure the following IBM WAN
Adapters:
• IBM PCI WAN 2 Port S91
• IBM PCI WAN MultiPort T1/E1 P92
• IBM PCI WAN MultiPort T1/E1 S94
IBM PCI WAN 2 Port S91
The IBM PCI WAN 2 Port S91 is a PCI Plug-and-Play (PnP) card that offers
X.25 connectivity through a high-speed port (supporting V.24, V.35, EIA-530,
V.36/RS-449, or X.21 interfaces) at speeds of up to 2 Mbps, and/or through an
ISDN BRI port at speeds of up to 128 kbps (over the “D” channel or the “B”
channels).
Note The IBM PCI WAN 2 Port S91 also supports protocols such as SDLC, PPP, and Frame
Relay.
Hardware Features
The IBM PCI WAN 2 Port S91 features a 25 MHz Motorola 68302
microprocessor with 1 MB of RAM and 1 MB of FLASH memory. It has two
communications ports:
• an ISDN BRI port supporting transfer rates of up to 128 kbps (over the “D”
channel or the “B” channels)
• a Very High-Speed Interface (VHSI) port, supporting full duplex communi-
cations over a V.24, V.35, EIA-530, V.36/RS-449, or X.21 interface at speeds
of up to 2 Mbps (depending on the type of interface selected)
Ease of Use
The VHSI port features automatic interface selection. The intelligent controller
on the IBM PCI WAN 2 Port S91 detects the type of cable connected to the port
and automatically selects the matching interface.
IBM PCI WAN MultiPort T1/E1 P92
The IBM PCI WAN MultiPort T1/E1 P92 allows stand-alone PCs or multiple
users on a Local Area Network (LAN) to make very high speed connections to
a Wide Area Network (WAN). These connections are typically made through the
IBM PCI WAN MultiPort T1/E1 P92 to external communications equipment
(including CSUs, DSUs, and synchronous and asynchronous modems) to
provide access to WAN lines. Direct connections to a host computer or to another
IBM PCI WAN MultiPort T1/E1 P92 are also supported.
