Slot modes
The slots of a 1643 AM and 1643 AMS system can be occupied by a "unit". A unit is
either a main unit or a tributary unit. Usually, a unit occupies a single slot. However,
some tributary units (i.e. legacy option boards, mounted on an adapter card) occupy
two slots.
These slot modes exist:
ASSIGNED
AUTO
UNASSIGNED
Notes:
1. A compatible unit is a unit which is permissible for the respective slot. Please refer to the 1643 AM and
1643 AMS Applications and Planning Guide for compatibility information.
Monitoring modes
Monitoring modes are applicable to physical ports, trail termination points, and non
intrusive monitoring (NIM) points. Monitoring modes can be provisioned for each type
of physical port or termination point (TP) individually.
The setting of the monitoring mode determines whether an incoming signal will be
processed, including alarm supervision and performance monitoring.
These monitoring modes exist:

The slot is configured to contain a unit of a specified type. If a unit of a
1
compatible type is present in the slot, then the unit provides service, except
for transmission ports. Transmission ports are controlled by the port mode
configuration, see "Monitoring modes" (p.
Assigned slots are monitored for equipment defects, and corresponding alarm
messages will be reported.
The slot may still be empty, but is pre-configured to contain a unit of a
specific type.
This slot mode corresponds to the UNASSIGNED mode as long as no unit is
present. As soon as the presence of a compatible unit is detected the slot
mode is automatically changed to ASSIGNED. Note that if a unit of an
incompatible type is detected, a "Wrong Unit Present" alarm (UNITcWUP)
will be reported.
The slot is configured to be empty. If a unit is present in an UNASSIGNED
slot then the unit does not provide service; if there are ports on the unit,
then incoming signals will not be processed, and will not be monitored for
defects.
No alarms will be generated in case of a fault or error condition on a unit in
an UNASSIGNED slot; only its presence will be signaled as a fault
condition ("Unit present in unassigned slot", UPUS).
