MODULES (VCOM-X) > STATISTICS > USAGE TIME

Read security: 5

Measures the total elapsed time that a packet voice device has the status BUSY. 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:

Frames(ATLAS)Total = FramesATLAS + Frames(ATLAS)Dropped

See the ATLAS DROP definition below for a description of the term: Frames(ATLAS)Dropped

MODULES (VCOM-X) > 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.

MODULES (VCOM-X) > STATISTICS > VCOM FRMS

Read security: 5

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(VCOM)Total = FramesVCOM + Frames(VCOM)Dropped

See the VCOM DROP definition below for a description of the term: Frames(VCOM)Dropped
