ADTRAN 1200305L1 system manual Modules ADPCM-32 Statistics Atlas Drop

Section 4, User Interface Guide ATLAS 550 System Manual

MODULES (ADPCM-32) > STATISTICS > 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.

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.

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:

Frames(ADPCM)Total = FramesADPCM + Frames(ADPCM)Dropped

See the ADPCM-32 DROP definition below for a description of the term: Frames(ADPCM)Dropped

MODULES (ADPCM-32) > STATISTICS > ADPCM-32 DROP

Read security: 5

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.

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.

MODULES (ADPCM-32) > STATISTICS > CLEAR

Write security: 3; Read security: 5

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.

Resetting these performance counters has no effect on the performance values accessible via the SNMP network management interface.
