3.2.1 WAN Interface Configuration Screen Fields
This section describes the WAN Interface Configuration screen fields.
Interface Number (Modifiable)
Displays the active Interface Number. Used to configure the Interface
Numbers that were assigned to the Timeslots on the WAN Physical
Configuration screen.
Max Xmit Unit (Modifiable)
Displays the maximum packet size that can be transmitted on the selected
interface. The default settings for this field depend on the Protocol
Manager chosen.
ProtMgr Iface (Modifiable)
Interface number used for the Protocol Manager chosen.
Active Protocol (Read-Only)
Displays the active OSI layer protocol (Protocol Manager) chosen for the
WPIM-T1/DDS. There is one set of parameters displayed for FR, and one
set for PPP. Refer to
Section 3.2.1.1 for information on the Active
Protocol set to Frame Relay, and Section 3.2.1.2 for PPP information.
3.2.1.1 Frame Relay as the Protocol Manager
Refer to Figure 3-4 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-T1/DDS can learn the DLCIs dynamically from the
switch.
DLCI DCP En (Toggle)
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.
