Active Protocol (Read-Only)

Displays the active OSI layer protocol (Protocol Manager) chosen for the 
WPIM-RT1. There is one set of parameters displayed for FR, and one set 
for PPP. Refer to

set to Frame Relay, and 

 for PPP information.

 for the following parameters displayed for FR.

FR LMI (Selectable)

Frame Relay Link Management Interface. This field displays ANSI_94, 
NO LMI, T1.617-D or Q.933-A. The NO LMI setting is for specialized 
applications in which no Frame Relay Link Management is available or 
required.

DLCI Address (Modifiable)

Data Link Connection Identifier given by the Service Provider. Can be set 
to values from 0-1023, depending on the protocol, when available for 
modification with certain protocol modes. The values 0-15 and 1008-1022 
are reserved DLCI addresses. When using FR PtoMP as the Protocol 
Manager, the WPIM-RT1 can learn the DLCIs dynamically from the 
switch.

Enables the user to turn Data Compression Protocol On or Off on an 
application port per application port basis when available. The DLCI port 
must be entered to change compression.
