ATLAS 800 Series System Manual VCOM Option Module
Statistics
See
ATLAS Drop on page 171 for a description of the term:
ATLAS Drop Write security: 4; Read security: 5
A counter that measures each frame that is dropped or discarded during
communication between the ATLAS 800 Series 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 800 Series system.
The discarded frame indicated by this value does not reflect network-level performance
management, but indicates an anomalous condition within the ATLAS 830 unit.
Persistently dropped frames may indicate a problem with the ATLAS 830 unit or the
Voice Compression Resource Module.
VCOM Frms Write security: 4; Read security: 5
Counts every frame successfully sent to or received from the ATLAS 800 Series
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 800
Series:
See VCOM Drop on page 172 for a description of the term:
VCOM Drop Write security: 4; Read security: 5
Counter that measures each frame dropped or discarded by ATLAS 800 Series
during communication with the ATLAS 800 Series 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 800 Series system.
The discarded frame indicated by this value does not reflect network-level performance
management but indicates an anomalous condition within the ATLAS 830 unit.
Persistently dropped frames may indicate a problem with the ATLAS 830 unit or the
VCOM module.
Clear Write security: 4; Read security: 5
Resets the elapsed usage time and frame counters for this packet voice device.
Ordinarily, users won’t 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.
