Local Management for DDS Service. Cabletron Systems WPIM-T1/DDS, WPIM T1/DDS, T1, WPIM T1
Below you will find brief information for WPIM T1/DDS. This WAN Interface Module provides T1 or DDS connectivity for Cabletron Systems platforms like the CSX400 and HSIM-W6. It features a built-in CSU/DSU for direct line connection, supporting full or fractional T1 and DDS services. Configuration is done via QuickSET or Local Management, allowing setup of WAN protocols like PPP and Frame Relay.

CHAPTER 4
LOCAL MANAGEMENT FOR DDS SERVICE
This chapter explains how to configure the WPIM-T1/DDS through Local
Management. The WAN Physical Configuration screen and the WAN
Interface Configuration screen display as Local Management menu selections after the WPIM-T1/DDS is installed into a host platform. Refer to the host platform User’s Guide for instructions about how to set up and access Local Management.
Sections of this chapter include the following:
•
The WAN Physical Configuration Screen, Section 4.1
• The WAN Interface Configuration Screen,
• WPIM-DDS Configuration,
to gain an understanding of the
WPIM-T1/DDS Local Management screens. Section 4.3
examples for setting up the WPIM-DDS in a PPP or Frame Relay environment.
NOTE
The WPIM-T1/DDS cannot operate in both T1 and DDS mode at the same time. The user must choose the appropriate
service, but can change it when desired. Refer to Section 2.3.1
to choose the mode.
When the WPIM-T1/DDS is first powered up, the default is T1.

Displays the type of WPIM installed. For the WPIM-T1/DDS, the Type field displays the service selected. When T1 service is selected, T1 is displayed. When DDS service is selected, DDS is displayed.
WPIM # (Read-Only)
Displays the number of the slot in which the WPIM resides.
Mgr Type (Selectable)
The type of protocol manager is chosen in this field. For the DDS mode of the WPIM-T1/DDS, the available options are NONE, PPP, FR PtoMP,
FR PtoP, and HDLC. The field defaults to NONE.
Max VCs (Modifiable)
Displays the maximum number of virtual circuits (interfaces) that the
WPIM-T1/DDS may have with the protocol chosen.
Next IF (Read-Only)

ENTER. The message “SAVE DONE!” displays and Local
Management saves the changes to memory. “REBOOT IN
PROGRESS......” displays and the host platform reboots. Re-entry to management is necessary for any further configuration.
4.3.2
DDS Service Interface Configuration
The WAN Interface Configuration screen is accessed through the WAN
Physical Configuration screen. Access the WAN Interface Configuration screen (
Figure 4-2 ) 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 through Local Management.

2.
If Frame Relay was selected, use the arrow keys to highlight FR LMI.
Press the SPACE bar to select ANSI_94, NO LMI, T1.617-D, or
Q.933-A, then press ENTER.
If NO LMI was selected, complete the following:
• Use the arrow keys to highlight DLCI Address. This field can be set to values from 0-1023. The values 16-991 are typically used for virtual circuits.
• Use the arrow keys to highlight Circuit State. Press the SPACE bar to select Active, then press ENTER.
3.
If PPP was selected as the Protocol Manager instead of Frame Relay, the Max Xmit Unit setting may be changed from the default of 1526 if desired.
4.
Make any changes to the available settings as desired.
5.
Use the arrow keys to highlight the SAVE command. Press ENTER.
The message “Save Done!” appears and Local Management saves the changes to memory.
The WAN configuration is complete. Communication between the
WPIM-T1/DDS and the service provider’s switch takes approximately one to 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.
