Ext Leads: Rate
Next ExtLd Rate
External Leads . Controls the use of the general-purpose leads on the EIA-232-D/V.24 interface for Port 1
except when Rate is selected. These leads can be controlled and monitored from the DCP or a 6700 or
6800 Series NMS.
ExtLd — Enables Pins 12 and 13 as output (control) and Pins 19 and 23 as input (alarm) leads. When
enabled, Pins 12 and 13 output +12V when ON and –12V when Off. Pins 19 and 23 recognize
voltages from +2.2V to +12V as ON (reported as an external alarm) and –12V to +.8V as Off.
Rate — If the TDM or MCMP option is installed, Pin 12 on each port can be used to control speed
selection to cause an extended modem to change speed to match the backup port speed.
Pin 12 on all ports is turned Off at the same time to indicate that the TDM is in fallback. If a port
should not fall back and remain at the same speed, then the fallback feature in the DCE
connected to that port should not be enabled. This feature only works with firmware greater
than version 3.8.
RPowr — Functions similarly to ExtLd, but the inputs report power failure or fan alarms when a redundant
power supply is installed in the COMSPHERE 3000 Series Carrier.
CCN by EL: Disab
Next Enab Disab
Configuration Change Notification by External Leads . Controls the use of the general-purpose output leads
to set a CCN event. This configuration option only has an effect if Ext Leads is set to ExtLd and the protocol
is ADp.
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 . Controls 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 NMS.
Enab — If DTR lead turns Off for 30 seconds, the DSU generates an alarm.
Disab — Regardless of how long the DTR lead is Off, no alarm is generated.
