Setting External Lead States; Setting Thresholds - Paradyne COMSPHERE 6800 Series Communications Products Support Configuration Manual

Setting External Lead States

The External Leads State is a feature that makes a pair of leads on the COMSPHERE device
available for any user-created implementation. The external leads can be used to trigger an
electro-mechanical device, reset computer or terminal equipment at a remote site, or as part of a
security system. The external leads are turned on or off by executing the Change External Leads
States (chels) command.
Refer to the user manual that came with your device for more information on device-specific
external leads. For more information on the Change External Leads States (chels) command, refer
to the COMSPHERE 6800 Series Network Management System Communications Products Support
Command Reference Manual.

Setting Thresholds

The 6800 Series NMS gives you the ability to change the thresholds that allow you to monitor and
track the performance of a 3400/4400 Series device and to monitor channel and line conditions of
the analog private line. The following threshold parameters are provided.
All COMSPHERE APL modems (with the exception of the 3900 Series modems) have default
threshold values that may be acceptable to your needs. If these values are acceptable, you do not
have to set a new value. A threshold value may be changed after a network reconfiguration, or if a
particular facility is causing problems and warrants closer attention.
The Change Thresholds (cht) command can be executed to set thresholds for those parameters that
define alarms. After setting the thresholds, you can display them by executing the Display
Thresholds (dst) command.
These commands are available from the Device Diagnostics and Fault Isolation option in the
System Management window accessed via the Manager task. Refer to the COMSPHERE 6800
Series Network Management System Communications Products Support Command Reference
Manual for additional information on these commands.
