Digital Bridge Port (MUX Funct: CBrdg or EBrdg) Configuration Options*
DTR Alarm: Disab
Next Enab Disab Prev
Data Terminal Ready Alarm. Causes the DSU to report an alarm for the port if the port’s DTR lead is Off for
more than 30 seconds. The DCP displays DTR Alarm and reports the alarm to NMS. The ability to report
DTR as an alarm is independent of port speed; the alarm is reported even if the speed of the port is set to
0 bps.
Enab
—
If the port’s DTR lead turns Off for 30 seconds, the DSU reports an alarm.
Disab
—
Regardless how long the port’s DTR lead is Off, no alarm is reported.
AntiStream: Disab
Next Chang Prev
Antistreaming. Specifies if the port is monitored for streaming terminal alarms. The purpose of antistreaming
is to provide network protection against a streaming DTE (a defective DTE that has its RTS lead constantly
turned ON) by disabling the DTE.
If the DTE turns ON RTS longer than the time specified for the AntiStream configuration option, the tributary
DSU turns ON its alarm indicator and clamps the port’s leads until RTS is turned Off. Although the DTE port
is not allowed to send, it can still respond to commands and is capable of being tested or disabled. A test
resets the streaming terminal timer. When the test is completed, the timer starts again.
Upon detecting that RTS is no longer turned ON, the DSU turns Off its alarm and resets the streaming timer,
and allows the DTE port to send data once again.
This configuration option has an effect only at a port configured with RTS Control set to DTE. It is disabled
when RTS Control is set to FrcOn.
Chang —
Set timer to any value from 1 to 100 seconds in increments of 1, or Disab. Incrementing the
value when it reaches 100 disables this configuration option. When using async terminal, enter
0 (zero) to disable.
DSR FrcOn: Disab
Next Enab Disab Prev
Data Set Ready Forced On. Overrides any other options controlling the Data Set Ready lead.
Enab
—
DSR remains ON as long as the DSU is working, regardless of tests and network alarms.
Disab
—
DSR functions as an active lead reflecting various test and alarm conditions and other options.
DSR on Tst: Disab
Next Enab Disab Prev
Data Set Ready On in Test. Controls the behavior of the DSR lead during testing.
Enab
—
DSR is ON continuously during testing, allowing a DTE that relies on DSR being ON to send
test messages to the DSU.
Disab
—
DSR is Off during testing.
* For the DCE port (first port of the digital bridge), the Elastic Store is automatically enabled and RTS Control is
automatically set to =DTE. All other configuration options for the DCE port are turned Off. The menu paths for Port 2
through Port 6 are identical.
