L2 PROTOCOL (TDM–T1–FRE) > CONFIG > MAINTENANCE PROTOCOL

The Frame Relay maintenance protocol is used on the WAN port. The maintenance protocol is used to send link status and virtual circuit information between Frame Relay switches and other devices (such as routers that communicate with them). Possible choices are as follows:

ANNEX D (ANSI)	(Default) This ANSI standard ANSI T1.617-D and is the most commonly
	used in the United States.
ANNEX A (Q933A)	This is the CCITT European standard, ITU-T Q.933-A.
LMI	This was developed by a vendor consortium and is also known as the
	“Consortium” management interface specification. It is still used by some
	carriers in the United States.
STATIC (NO SIG)	This should be selected when there is no Frame Relay switch in the
	circuit. The DLCIs are assigned in the DLCI Mapping and must be the
	same for the device it will communicate with.

L2 PROTOCOL (TDM–T1–FRE) > CONFIG > POLLING FREQUENCY (5-30)

This parameter is the interval that the unit polls the Frame Relay switch using the maintenance protocol selected. The unit is required to poll the Frame Relay switch periodically to determine whether the link is active. The value is in seconds and ranges from 5 to 30 seconds with a default of 10 SECONDS.

L2 PROTOCOL (TDM–T1–FRE) > CONFIG > DLCI MAPPING

This menu allows each DLCI to be mapped to a particular Frame Relay maintenance protocol. Each protocol parameter can be individually configured for each DLCI. By factory default, the DLCI map is empty.

When empty and a maintenance protocol other than the static is used, the unit will poll the switch to determine which DLCIs are active. If the Total Access 6XX learns a new DLCI not listed in the DLCI Map, an entry is added for that DLCI in the PVC Status table. The learned DLCIs are listed as INACTIVE until the user configures them in the DLCI Map.

To insert a new profile, press the I key when over the Num column. A new inserted profile will always be set up with the default parameters. To copy parameters from an old profile to this newly inserted profile, use the copy (C) and paste (P) keys. Entire configuration trees can be copied with this method.

To delete an unused profile, use the D key when the cursor is over the number in the Num column. Once deleted, the profile is gone permanently.

L2 PROTOCOL (TDM–T1–FRE) > CONFIG > DLCI MAPPING > NUM

Displays the index number in the DLCI mapping table.

L2 PROTOCOL (TDM–T1–FRE) > CONFIG > DLCI MAPPING > ACTIVE

The default value is YES. If set to NO, the unit will ignore the virtual circuit with this DLCI.
