7-6 Preliminary November 23, 1998 MultiVoice Gateway for the MAX— User’s Guide
Configuring Frame Relay
Configuring the logical link to a Frame Relay switch
MRU (Maximum Receive Units)
The MRU parameter specifies the maximum number of bytes the MultiVoice Gateway can
receive in a single packet across this link. Usually the default of 1532 is the right setting,
unless the far end device requires a lower number.
Examples of Frame Relay profile configuration
This section shows an example of Frame Relay profile configuration for each type of Frame
Relay interface: NNI, UNI-DCE, and UNI-DTE.
Configuring an NNI interface
In this example, the MultiVoice Gateway has a nailed connection to another Frame Relay
switch, and the connection uses an NNI interface configuration. Figure 7-6 shows the
connection.
Figure 7-6. Example of NNI connection to another switch
To configure the Frame Relay profile for this NNI interface:
1 Open a Frame Relay profile.
2 Assign the profile a name and activate it:
Ethernet
Frame Relay
Name=ATT-NNI
Active=Yes
3 Set the FR Type to NNI:
FR Type=NNI
4 Set up the nailed connection to the remote switch, and specify the data service for the link.
For example:
Call Type=Nailed
Nailed Grp=1
Data Svc=64k
5 Specify the link management protocol and its configuration parameters. For example:
Link Mgmt=T1.617D
N391=6
T391=10
T392=15
MRU=1532
6 Close the Frame Relay profile.
