MODULES (ADPCM-32) > STATISTIC S > ATLAS DROP
Read security: 5
A counter that measures each frame that is dropped or discarded during communication between the
ATLAS 550 and the packet voice device; i.e., ATLAS Frames Dropped. The exchange protocol is designed
so that no frames should be discarded during this operation. A consistent pattern of dropped frames by a
given packet voice device may indicate a faulty packet voice device or an overloaded ATLAS 550 system.

Counts every frame successfully sent to or received from the ATLAS 550 system controller. This is an
indication of activity but does not indicate the actual amount of packet data exchanged. The following
equation gives the total number of frames handled for this packet voice device by the ATLAS 550:
See the ADPCM-32 DROP definition below for a description of the term:

Counter that measures each frame dropped or discarded by ATLAS 550 during communication with the
ATLAS 550 system controller about a packet voice device. The exchange protocol is designed so that no
frames should be discarded during this operation. A consistent pattern of dropped frames by a given packet
voice device may indicate a faulty packet voice device or an overloaded ATLAS 550 system.

Resets the elapsed usage time and frame counters for this packet voice device. Ordinarily, users will not
reset these performance measurements. However, this feature can be useful when testing that a suspected
problem has been resolved and when zeroing the various counters would make observing future events
easier.
The discarded frame indicated by this value does not reflect network-level performance
management, but indicates an anomalous condition within the ATLAS 550 unit.
Persistently dropped frames may indicate a problem with the ATLAS 550 unit or the Voice
Compression Resource Module.
The discarded frame indicated by this value does not reflect network-level performance
management but indicates an anomalous condition within the ATLAS 550 unit. Persistently
dropped frames may indicate a problem with the ATLAS 550 unit or the 32 Channel
ADPCM Resource Module.
Resetting these performance counters has no effect on the performance values accessible
via the SNMP network management interface.
