DSU Port Configuration Options
LL by DTE: Disab
Next Enab Disab Prev
Local Loopback by DTE
. Controls using Pin L of the V.35 interface by the DTE to initiate a Local Loopback when the
DSU is the active device. Whenever this lead is ON, the Local Loopback overrides any other diagnostic tests run by the
network.
Enab — The DTE forces the DSU into Local Loopback when the signal on Pin L is turned ON. Local Loopback
ends when the signal is dropped.
Disab — The DTE will not initiate Local Loopback in response to the signal on Pin L.
Bilat Lpbk:Disab
Next Enab Disab Prev
Bilateral Loopback
. If this configuration option is enabled, a DTE Loopback occurs when a Digital Loopback occurs.
Enab — When enabled, DTE Loopback occurs whenever a Digital Loopback occurs.
Disab — Disables Bilateral Loopback.
DTR Alarm: Disab
Next Enab Disab Prev
Data Terminal Ready Alarm
. Causes the DSU to generate an alarm if DTR over the V.35 port 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.

Port Speed
. If this value is set to less than the DBM rate, the DBM performs rate adaption. Rates above 14.4 kbps will
only be displayed when a Switched 56 DBM is installed; 14.4 kbps will not be displayed for a 12.0 kbps DBM.
56 to — Selects the port speed. When a V.32 DBM is installed and the DiDg configuration is loaded the
1.2 default is 9.6 kbps. When a Switched 56 DBM with SyBC or SyBT configuration, the default is 56 kbps.
Disab — Sets the port speed to 0.
