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 management link
interface or LMI. The management protocol link must agree with your service provider. In most cases, the sig

naling setting may be the only variable you will need to change.
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
Do the following to change the signaling method:
1. Click on the
Signaling
drop-down menu and select
