Introduction
PRODUCT OVERVIEW
The ADTRAN Router Option Module installs in the option slot of
the TSU muliplexer family of products and provides integrated rout-
ing capability access frame relay or point-to-point networks.
Basic Functions of Router Option Module
The Router Option Module provides the following basic functions:
LAN Bridge
Bridging provides a point-to-point connection between two local
area networks (LANs). The bridge learning function scans the
source and destination media access control (MAC) addresses of all
packets on its LAN and determines which packets should be trans-
mitted over the T1 link. Applications include connectivity between
single users or small offices to corporate LANs. The Router Option
Module uses the Spanning Tree Algorithm (IEEE 802.1d-ISO/
IEC10038), which provides a loop-free topology and redundancy.
IP Router
The Router Option Module can function as an IP router using the
Routing Information Protocol (RIP) for advertising and learning
routes among other routers. Static routes may also be entered into
the routing table.
IPX Router
IPX routers and services can be exchanged between the Router Op-
tion Module and other devices using RIP and Service Advertising
Protocol (SAP). Watch dog serialization filtering and spoofing can
permit the ISDN to be idle during no application traffic periods.
