WPIM-DI Local Management Guide 2-3
Chapter 2: Local Management
NOTE
The service provider (i.e., AT&T, Sprint, MCI, NYNEX, etc.) determines the settings for the following fields. Consult the service provider for the correct settings.
NI/DI Timeslot View
Displays the status of the Timeslot Configuration table. This field toggles between Active and New. The Active setting displays current Timeslot
Configuration table settings. The New setting allows you to change
Timeslot Configuration table settings. The default setting is Active . The default setting for the Timeslot Configuration table is all Timeslots not assigned ( 000 ).

2-4 WPIM-DI Local Management Guide
The WAN Physical Configuration Screen
NI/DI Loopback
Displays the loopback for the WPIM-DI. Loopback is a testing procedure that segments the line and allows the user to isolate faults. This field toggles between None, Line-Loop, and Payload-Loop. In Line-Loop the entire T1 is looped back. In Payload-Loop only the 24 timeslots are looped back. The NI/DI Tx Clock Source must be in Loop Timing mode to use this option. The default setting is None .
DI Enabled
Displays the status of the Drop-and-Insert function of the WPIM-DI. This field steps between On, Off, and diDataEnable. Choosing On allows another device (e.g., WPIM-T1) that is connected to the DI interface of the WPIM-DI to use any timeslots that the WPIM-DI is not using (Drop and Insert is enabled between the two ports). The data from the host device passes through the NI port. Choosing Off allows the Network
Interface to be used as a standard T-1 port. Choosing diDataEnable enables Drop and Insert, and data from the host device will pass through the DI port. The default setting is On.
NOTE
When the diDataEnable option is selected in the DI Enabled field, data from the host device passes through the DI port and not the NI port on the WPIM-DI.
2.1.2.1
WPIM-DI Timeslot Configuration Table
The WPIM Timeslot Configuration table allows you to configure the way in which the WAN module uses the T-1 line. The configuration table consists of 24 Timeslots. You must assign each Timeslot an Interface number (for example, 002 for an active Interface number or 000 if the
Timeslot is not used). When you lease an entire T-1 line, you can use all
24 Timeslots (the full T-1 bandwidth). If you lease only a fraction of the
T-1, the service provider tells you which Timeslots to use.
The WPIM-DI supports Time Division Multiplexing (TDM) allowing channelization of circuits (Timeslots) within the public network. You can use Timeslots any way you choose. When using the WPIM-DI, you have the option of implementing all the available leased Timeslots with the
WPIM-DI, or you may map any of the available Timeslots to another
WAN module through the DI interface.
WPIM-DI Local Management Guide 2-5
Chapter 2: Local Management
For example, if your CSX400 has access to a full T-1 (24 Timeslots), and you want to communicate with two other sites through the WPIM-DI, your configuration might look like the sample configuration shown in
Figure 2-2.

Figure 2-2 Sample Network Configuration #1
Figure 2-3 shows a sample Timeslot configuration for the three sites shown in Figure 2-2. Of the 24 Timeslots, Site #1 uses 16 to communicate with Site #2 and the remaining 8 to communicate with Site #3. This configuration varies tremendously depending on how the service provider maps out the T-1 Timeslots. Your service provider will tell you which
Timeslots are active.

WPIM-DI Local Management Guide
NOTE
The WAN Physical Configuration Screen
Site #1 is using the full T-1, so all the Timeslots must have an Interface assignment. Site #2 and Site #3 only use a fraction of the T-1, but the total quantity of Timeslots must match those of Site #1. Unused Timeslots receive an Interface number of 000.
The Interface numbers of Site #1, Site #2 and Site #3 do not have to match. Only the quantity of Timeslots must match (the service provider assigns the Timeslots).
Mapping Unused Timeslots
In the previous example, the WPIM-DI made use of all 24 timeslots.
None of the timeslots were mapped to another device and the Drop and
Insert function was not used. If, however, you wanted another WAN device (e.g., a WPIM-T1) at the same site as the WPIM-DI to be able to communicate with Site #3, your configuration might look like the sample configuration shown in Figure 2-4.

NOTE
When the WPIM-DI Physical Configuration screen is saved and the Drop-and-Insert function is enabled, any timeslots initially set to 000 in the Timeslot Configuration table change to DI to reflect that these timeslots are mapped to the DI interface.
In order to map unused timeslots to another device connected to the DI port of the WPIM-DI, the DI Enable option on the WAN
Physical Configuration screen must be set to On.

This field displays JBZS, INV-HDLC, or None. The default setting for this field is NONE.
Active Protocol
Displays the active OSI Layer protocol. This field displays
PPP (Point-to-Point), FR (Frame Relay), or NONE. The default setting is
NONE.
If PPP is selected, the following field appears:
PPP Type : This field displays BNCP or LEX. The default setting is BNCP.
If FR is selected, the following field appears:
FR LMP : This field displays the Link Management
Protocol NO LMI, Q.933-A or T1.617-D. The default setting is T1.617-D.
If NO LMI is selected for FR LMP, the following fields are displayed:
DLCI Address : This field can be set to values from 0-1023. The values 0-15 and 1008-1022 are reserved Data
Link Connection Identifiers (DLCI) addresses.
The values 16-991 are typically used for virtual circuits.
Circuit State : Steps between Active, Inactive and Invalid. The default setting is Active.
PT#
Displays the application ports (bridge ports) available from the host platform to the WAN. If the active protocol is PPP, Local Management assigns only one application port per interface number (IF#). If the active protocol is Frame Relay, Local Management assigns the available WAN bridge ports from the host platform, one per DLCI.
2-10 WPIM-DI Local Management Guide
WPIM-DI Configuration
You can assign WAN application ports to the 24 interfaces for the PPP configuration that suits your needs. In a Frame Relay configuration, you can assign all WAN application ports to one interface. In this example, the remaining 23 interfaces would not have WAN application ports available.
The quantity of application ports for a Frame Relay network is determined by the quantity of DLCIs assigned to that Interface. This is determined either manually or by the Link Management Protocol (LMP).
IF#
Displays the Interface that is associated with the application port.
LID
Displays the Link Identifier. If the active protocol is Frame Relay, the
Data Link Connection Identifier is displayed. If the active protocol for this interface is PPP, then PPP appears in this field.
STATE
Displays the status of the application port. If the active protocol is Frame
Relay, this field displays the status as Active, Inactive, or Disabled (for no
LMI). If the active protocol is PPP, this field displays UP (for active) or
DOWN (for inactive).
