WAN Configuration2-12Local Management User’s GuideFrame Relay as the Protocol ManagerRefer to Figure 2-3 for the following parameters displayed for FR.FR LMI (Selectable) — Frame Relay Link Management Interface. Selectable states are based onthe applicable RFC selections. The applicable switch type is chosen based on the switch type usedby the Service Provider. The choices are: No LMI, T1.617-D, Q.933-A, and ANSI_94. TheNO LMI setting is for specialized applications in which no Frame Relay Link Management isavailable or required.DLCI Address (Modifiable) — Data Link Connection Identifier given by the Service Provider. Itis the PVC mapped index number of the connection identifier. The Telco switch assigns a virtualport to each DLCI. Can be set to values from 0-1023, depending on the protocol, when availablefor modification with certain protocol modes. The values 0-15 and 1008-1022 are reserved DLCIaddresses. When using FR PtoMP as the Protocol Manager, the HSIM or CyberSWITCH can learnthe DLCIs dynamically from the switch.DLCI DCP En (Toggle) — The Data Compression Protocol (DCP) can be enabled or disabled inthis field, on an application port per application port basis, when available. The DLCI port must beentered to change compression. Use the SPACE bar to toggle the field and ENTER to select eitherOn or Off.DLCI DCP Stat (Read-Only) — Displays the current negotiated status of compression.Comp Ratio (Read-Only) — Displays the Compression Ratio, which is the ratio ofuncompressed to compressed data.Circuit State (Selectable) — The field initially displays the state of the DLCI circuit, and can bemodified. Steps through Active, Inactive and Invalid.NOTEIn FR PToMP mode, DLCI’s can be learned dynamically and do not need to beentered in the screen. Once a DLCI is entered, it becomes a “statically” entered DLCI.To remove a statically-entered DLCI, enter the IF# of the DLCI (see the InterfaceScreen), then enter “Invalid” into the Circuit State field, and then SAVE the changes.
