Understanding the Frame Relay connection parameters
This section provides some background information about the Frame Relay connection
parameters. For more information about each parameter, see the MAX Reference Guide.
Gateway connections (Encaps=FR)
Gateway connections require FR encapsulation, a Frame Relay profile name, and a DLCI.
Your Frame Relay provider tells you the DLCI to assign to each connection.
A Connection profile that specifies Frame Relay encapsulation must include a DLCI to
identify the first hop of a Permanent Virtual Circuit (PVC). The MultiVoice Gateway does not
allow you to enter duplicate DLCIs, except when they are carried by separate physical links
specified in different Frame Relay profiles.
Frame Relay circuits (Encaps=FR_CIR)
A circuit is a PVC segment configured in two Connection profiles. Data coming in on the
DLCI configured in one Connection profile is switched to the DLCI configured in the other.
Data gets dropped if the circuit has only one DLCI. If more than two Connection profiles
specify the same circuit name, the MultiVoice Gateway uses only two DLCIs.
In a circuit, both Connection profiles must specify FR_CIR encapsulation and the same circuit
name. Each profile must specify a unique DLCI. The MultiVoice Gateway does not allow you
to enter duplicate DLCIs, except when separate physical links specified in different Frame
Relay profiles carry duplicate DLCIs.
Examples of connection configuration
This section shows examples of Connection profile configuration for Frame Relay gateway,
circuit, and redirect configurations.
Configuring a Frame Relay gateway connection
This example shows how to configure a Frame Relay gateway connection. It presumes that
dial-in users who need to reach the distant IP network have valid Connection profiles (or
