Chapter 13: AI2524 Frame Relay
Configuration Steps
Introduction
This chapter describes how to perform a variety of frame relay config-
uration tasks and enable frame relay encapsulation.
Frame Relay
Hardware
Configuration
Routers and access servers can connect directly to:
z The Frame Relay switch
z A channel service unit/digital service unit (CSU/DSU), which
then connects to a remote Frame Relay switch
A Frame Relay network is not required to support only routers that are
connected directly or only routers connected via CSU/DSUs. Within
network, some routers can connect to a Frame Relay switch through
direct connection and others through connections via CSU/DSUs.
However, a single router interface configured for Frame Relay can be
only one or the other.
The CSU/DSU converts V.35 or RS-449 signals to the properly coded
T1 transmission signal for successful reception by the Frame Relay
network.
Figure 13-1 illustrates the connections between the different
components.
