3.7 Routers
Digital has an interoperable family of flexible, full-function local, and wide area
network multiprotocol routers. The following two modules are available for use in
the DEChub platforms or as a standalone device:
• DECwanrouter 90-802.3/Ethernet to a single 64 Kb/s port.
• DECwanrouter 90EW-802.3/Ethernet to two 64 Kb/s ports.
3.7.1 DECwanrouter 90 and DECwanrouter 90EW
The DECwanrouters 90 and 90EW provide synchronous and asynchronous WAN
connections to an Ethernet LAN through a serial line. They offer low-cost, wide-area
access for remote sites and branch office LANs with light-to-medium multiprotocol
network traffic. The illustration in Figure 3–20 represents both the DECwanrouter 90
and 90EW network modules.
The modules provide connections across a variety of wide-area services including
leased lines, dial-up, X.25 and ISDN (using a terminal adapter). In addition to
supporting TCP/IP, DECnet, and OSI, the DECwanrouters support Novell IPX.
