(ATLAS Frames Dropped) Counter-measures each frame that is dropped or
discarded during communication between the ATLAS and the VoFR 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
VoFR device may indicate a faulty VoFR device or an overloaded ATLAS
system.
The discarded frame indicated by this value does not reflect network-
level performance
condition within the ATLAS unit. Persistently dropped frames may
indicate a problem with the ATLAS unit or VCOM Module.

Counts every frame successfully sent to or received from the ATLAS Sys-
tem Controller. This is an indication of activity but does not indicate the
actual amount of frame relay data exchanged. The following equation gives
the total number of frames handled for this VoFR device by the
VCOM Module:

Counter-measures each frame dropped or discarded by VCOM Module
during communication with the ATLAS System Controller about a VoFR
device. The exchange protocol is designed so that no frames should be dis-
carded during this operation. A consistent pattern of dropped frames by a
given VoFR device may indicate a faulty VoFR device or an overloaded
ATLAS system.
The discarded frame indicated by this value does not reflect network-
level performance management but indicates an anomalous
condition within the ATLAS unit. Persistently dropped frames may
indicate a problem with the ATLAS unit or the VCOM module.

Resets the elapsed usage time and frame counters for this VoFR 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.
