DLMI window
Each Frame Relay instance with the access server is known as the Data Link Management Interface or DLMI.
The access server software currently supports one Frame Relay Link, or DLMI, on each of the T1/E1 WAN
ports. Frame Relay has a set of protocols responsible for maintaining the link. This is known as the manage-
ment link interface or LMI. The management protocol link must agree with your service provider. In most
cases, the signaling setting may be the only variable you will need to change.
The DLMI window (see figure 41) is where you set-up Frame Relay or change configuration parameters.
Note Most of the factory default settings can be left as is when setting up
your link, requiring only minor changes to comply with your service
provider’s Frame Relay link configuration.

The common link management, or signaling, protocols are:
• LMI. Frame Relay Forum Implementation agreement. Uses DLCI = 1023 for management
• Annex D. ANSI T1.617 Uses DLCI = 0 for management
• Annex A. ITU Q.933 Uses DLCI = 0 for management
The most commonly used protocol will be ansiT1-617-D(3).
Do the following to change the signaling method:
1. Click on the
Signaling
