COMSPHERE 3600 Series Data Service Units
LPDA Address: 001
Next Chang Prev
LPDA Address. Used to set the LPDA-2 address used by NetView. 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: 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;
required 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.
SNA Backup:Disab
Next Enab Disab
SNA Backup. Allows the DSU to respond to the NetView commands for establishing and dropping a dial backup
command (Call Out and Disconnect). When the SNA Backup configuration option is disabled, backup can still be
controlled from a 6700 or 6800 NMS; SNA Backup only needs to be enabled at the control DSU. For extended circuit
configurations, the extended circuit link can also be configured to respond to the NetView dial backup command by
turning on SNA Backup at the extended control DSU. This feature is not supported in multipoint configurations.
Enab – The 3600 Series DSU control responds to the NetView dial backup command.
Disab – The 3600 Series DSU control sends a Request Not Supported by DCE message to NetView upon receiving a
dial backup command.
Code 1: 582210

Code 1. Determines the DSU type and model reported to NetView for the DSU/CSU and Line Status test and
Transmit/Receive Test commands. The default values are the type (5822) and model (10) of the IBM 5822, which the
standalone 3610 DSU emulates for LPDA-2 monitoring. This value can be changed, but NetView may report an error if
the value is not a known IBM model number.
NOTE: The default value for the carrier-mounted 3611 DSU is 582218.
Code 2: 5822101
Next Chang Prev
Code 2. Determines the DSU type and model reported for the Call Out and the Disconnect commands. This
configuration option is normally set to the same value as Code 1. The last digit in the configuration option is used to tell
NetView that the DSU is either calling itself a DSU (1) or an APL modem (0 ) when responding to a NetView Dial Backup
command. It is needed because the NetView dial backup commands are meant for APL devices and a particular release
of NetView may not expect a DSU device to respond to an APL specific command.
NOTE: The default value for the carrier-mounted 3611 DSU is 5822181.
