Measures the total elapsed time that a packet voice device has the status 
B
USY
. The time is expressed with 
millisecond precision. Available packet voice devices are assigned new connections using a round-robin 
technique where all other available packet voice devices must be used before a given device is assigned a 
new connection. This scheme tends to use all packet voice devices evenly. If a given device shows 
significantly less elapsed usage time than other packet voice devices on the same ATLAS 550, that device 
may be faulty.

(ATLAS Frames) Counts every frame that the ATLAS 550 sends to or receives from the packet voice 
device. This count indicates activity but does not indicate the actual amount of frame relay data exchanged. 
The total number of frames handled by the packet voice device is given by the following equation:

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 
VCOM D
ROP
 definition below for a description of the term: 
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.
