CCN by EL: Disab
Next
Enab
Disab
Configuration Change Notification by External Leads . Controls using the general-purpose output leads to set a CCN
event. This configuration option only has an effect if Ext Leads is set to ExtLd.
Enab
—
Change in state of a general-purpose lead signals CCN to the NMS.
Disab
—
General-purpose lead changes do not set a CCN event.
DTR Alarm: Disab
Next
Enab
Disab
Data Terminal Ready Alarm . Causes the DSU to generate an alarm if DTR is Off for more than 30 seconds. The DCP
displays DTR Alarm and reports the alarm to the NMS.
Enab
—
If DTR lead turns Off for 30 seconds, the DSU generates an alarm.
Disab
—
Regardless how long the DTR lead is Off, no alarm is generated.
Async Sync: Enab for DiDg, Disab for SyBC and SyBT configurations
Next
Enab
Disab
Asynchronous-to-Synchronous Conversion . Sets the DBM port for asynchronous or synchronous operation.
Enab
—
Configures the DBM as asynchronous (asynchronous-to-synchronous conversion takes place).
Disab
—
Configures the DBM as synchronous.
AsyncBit/Char: 8 for DiDg configuration
Next
6
7
8
Asynchronous Bits per Character . Specifies the length of a character, including the parity bit but excluding the start and
stop bits. This configuration option only applies to the Dial Diagnostic (DiDg) configuration.
6 to 10 —
Selects the asynchronous bits per character. When Stop Bits is set to 2, 10 will not be displayed.
Stop Bits: 1 for DiDg configuration
Next
1
2
Prev
Stop Bits . Specifies the number of stop bits in an asynchronous character. This configuration option only applies to the
Dial Diagnostic (DiDg) configuration.
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 be displayed.
Overspeed: 2.3 for DiDg, not applicable for other configurations
Next
1.0
2.3
Overspeed . Selects the overspeed range of the asynchronous-to-synchronous converter. This configuration option is
only displayed when the Async Sync configuration option is enabled.
1.0
—
Selects the basic overspeed range. Basic range provides 1.0 % overspeed in the DTE or router
asynchronous data rate.
2.3
—
Selects the overspeed percentage for extended range. Extended range provides 2.3 % overspeed in the
DTE or router asynchronous data rate.
