LPDA-2 Operation . Allows the DSU to respond to LPDA-2 commands issued from NetViewt. This
configuration option must be enabled at the control DSU and each tributary DSU for proper SNA Diagnostic
Interface operation.
When a disruptive test is running at the control DSU, the FEP reports Test in Progress to the NetView
operator when the operator issues an LPDA-2 command. If the Test Mode (TM) jumper at the control DSU is
disabled, the control DSU may respond to an LPDA-2 command while running a test initiated by the NMS or
DCP. (The LPDA-2 command cannot propagate any farther than the control.) However, if the control DSU is
performing a Device Test or an End-to-End test, it ignores any NetView-initiated command.
Enab — The 3600 Series DSU responds to LPDA-2 commands. When enabled, it is recommended that
DSR FrcOn be set to Enab and CTS Cntrl set to RTS.
Disab — The 3600 Series DSU does not respond to LPDA-2 commands.

LPDA Address . Allows the LPDA-2 address used by NetView to be set. Choices are 1 through 255, in
decimal.
The following rules apply to control DSU address assignment:
1. Link Segment Level 1 (Primary Circuit). The control DSU closest to the NetView host is typically
assigned the address 1.
2. Link Segment Level 2 (Extended Circuit). The extended control DSU is typically assigned the address 2.
The following rules apply to tributary DSU address assignment:
1. Valid Addresses. Valid addresses for tributary DSUs range from 1 to 255.
2. Single DTE. The tributary DSU address is set to the Physical Unit (PU) address of the attached terminal
device. This constraint is imposed by NetView.
3. Extended Circuit. For configurations having extended circuits, the tributary DSU in the primary circuit is
set to 253. Address 253 (FD hex) is the broadcast LPDA-2 address.
