General Configuration Options
Stop Bits: 1
Next 1 2 Prev
Stop Bits. Specifies the number of stop bits in an asynchronous character. This configuration option only appears when
the Single-Port Async/Sync feature is installed and the Async→Sync configuration option is enabled.
1 to 2 – Selects the number of stop bits to be used. When the AsyncBit/Char configuration option is set to 10, 2 will not
appear.
Overspeed: 2.3
Next 1.0 2.3 Prev
Overspeed. Selects the overspeed percentage of the asynchronous-to-synchronous converter. This configuration option
only appears when the Single-Port Async/Sync feature is installed and the Async→Sync configuration option is enabled.
1.0
– Selects the basic overspeed range. Basic range provides 1.0% overspeed in the DTE asynchronous data rate.
2.3
– Selects the overspeed percentage for extended range. Extended range provides 2.3% overspeed in the DTE
asynchronous data rate.
PowerOnTst: Enab
Next Enab Disab Prev
Power On Test. This configuration option affects the power-up routine and Reset initiated from the Control branch.
Enab – Any installed DSU, DBM, and MUX performs all device tests during the initial power-up routine or when selecting
Reset from the Control branch.
Disab – The power-up routine and Reset will bypass lamp and device tests. Major device errors from communication
failures may result in a DDS, DBM, or MUX facility alarm.

LPDA-2 Configuration Options
LPDA-2: Disab
Next Enab Disab Prev
LPDA-2 Operation. Allows the DSU to respond to LPDA-2 commands issued from NetView. This configuration option
must be enabled at the control DSU and each tributary DSU for 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) switch S1-3 or S1-4 is disabled at the control DSU, the
control DSU may respond to an LPDA-2 command while running a test initiated by an NMS or front panel. The LPDA-2
command cannot propagate any farther than the control. 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.
