Local Bridge Modules.
A
local bridge module
allows you to
connect two Local Area Networks together to form an Extended
Local Area Network. It allows you to extend beyond the physical
limitations of a single network and provides sophisticated filtering
between the networks.
Contact your local supplier for further information.
The Terminal Server Module.
The
terminal server module
provides sixteen asynchronous ports to connect to terminals,
personal computers, printers and modems. Connection to these
ports is provided by two 50-way telco connectors, providing
maximum flexibility and good cable management. Port speeds
operate at up to 57.6 Kbps with both TCP/IP and DEC LAT
protocols. The module provides TCP/IP users with a complete
implementation of Telnet and full compliance with all Internet
protocols.
Contact your local supplier for further information.
The Remote Bridge Module And The Remote Control
Module.
The
remote bridge module
enables you to link
networks located at different sites, and provides sophisticated
filtering between those networks. It has an Ethernet port and one
or two WAN ports. The Ethernet port is the connection to the
LAN segment through the backplane of the MSH chassis. Each
WAN port requires a daughter board interface card which may be
one of seven types (X.21 (barriered and unbarriered), V.24, V.35,
V.36, G.703 or T1) allowing connection to all major network
termination unit interface standards.
In addition to the above, the
remote control module
offers
Bridge/Routing is a the Boundary Routing System Architecture
and PPP bridging.
