Line-Loop, and Payload-Loop. In Line-Loop the entire T1 line is looped back, including the framing bits, CRC, and the facility data link. This happens before the framer. In Payload-Loop, only the 24 time slots are looped back, which happens behind the framer, and does not include the framing bits, CRC, and facility data link. The WPIM-T1/DDS must be in
Loop-Timing mode to use this option. The default setting is None.
3.1.3
The WPIM Timeslot Configuration Table
The WPIM Timeslot Configuration table allows the user to configure the way in which the Cabletron Systems WAN module uses the T1 line. The configuration table consists of 24 Timeslots. Each Timeslot must be assigned an Interface number (for example, 002 for an active Interface number or 000 if the Timeslot is not used). When an entire T1 line is leased, all 24 Timeslots (the full T1 bandwidth) can be used. If only a fraction of the T1 line is leased, the service provider indicates which
Timeslots to use.
WPIM-T1/DDS User’s Guide 3-5
Chapter 3: Local Management for T1 Service
Timeslots can be utilized in any way chosen. The WPIM-T1/DDS in T1 mode supports Time Division Multiplexing (TDM) allowing channelization of circuits (Timeslots) within the public network. For example, if the WPIM-T1/DDS has access to a full T1 (24 Timeslots), and the user wants to communicate with two other sites, the configuration might look like that shown in
SITE #2
16 Timeslots
SITE #1
24 Timeslots
Telco Cloud
SITE #3
8 Timeslots
Figure 3-2 Sample Timeslot Configuration
1482_02
Figure 3-3 shows a sample configuration for three sites. 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 T1 Timeslots. The service provider indicates which Timeslots are active.

Multipoint, there is one interface to multiple DLCIs, and the DLCIs are dynamically learned. Backup can only be run on FR PtoP, not FR PtoMP.
NOTE
When changing from one protocol to another on a
WPIM-T1/DDS that has been operational, save NONE as the protocol before changing to another protocol.

Frame Relay Interface Configuration
Access the WAN Interface Configuration screen through the WAN
Physical Configuration screen, by using the arrow keys to highlight the
WAN INT CONFIG command, then press ENTER. Proceed with the following steps to configure the WAN Interface.
1.
Set the Interface Number that is being used for the WAN connection by typing the same number into the Interface Number field that was input into the timeslots in the WAN Physical Configuration screen,
then press ENTER (refer to the Note on page 3-19 ). For Frame Relay
PtoP, the interfaces are assigned when DLCIs are created (in this case a zero needs to be entered in this field).
2.
Use the arrow keys to highlight FR LMI. Press the SPACE bar to select ANSI_94, T1.617-D or Q.933-A, then press ENTER.
NOTE
The choice NO LMI under FR LMI is a test mode only and should not be used in a practical application.
3.
Make any changes to the available settings as desired.
4.
Use the arrow keys to highlight SAVE, then press ENTER. The message “SAVE DONE!” displays and Local Management saves the changes to memory.
In FR PtoP, the DLCIs must be entered statically, as they will not come up dynamically as in FR PtoMP.
In FR PtoMP, there is an option to statically enter the DLCIs in association with a Protocol Manager, the physical port and MIB II, using the DLCI field in the Interface screen. If the DLCI is not static, it will be deleted if the Frame Relay switch determines that the DLCI has been eliminated. If the Frame Relay switch previously reported status on a
DLCI, when it does not report the status of the DLCI, the DLCI and its associated information is deleted from the platform. Static entries are never deleted automatically. They must be deliberately deleted by the user. To enter a DLCI, it is set to “Inactive” and saved, but to delete a
DLCI, it must be accessed and entered as “Invalid” and saved.

Frame Relay Configuration
The WAN configuration is complete. Communications between the
WPIM-T1/DDS and the service provider’s switch takes approximately one or two minutes to complete. A status of Inactive displays on a DLCI per DLCI basis by default until both ends of the DLCI are configured correctly. Once both end devices have negotiated link management with the switches, and are configured correctly on a DLCI per DLCI basis, the status field displays Active.
