VCOM DROP
Read Security: 5
Counter-measures each frame dropped or discarded by VCOM Module
during communication with the ATLAS 550 system controller about aVoFR
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 550 system.
CLEAR
Read Security: 5; Write Security: 3
Resets the elapsed usage time and frame countersfor thisVoFR 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.
RELOADS
Read Security: 5
Number of times since reboot that this device has beenreloaded due to a
failure.
FAX C
APABILITY
The FAX Capability menu allows FAX transmissions to be enabled/dis-
abled.
ENABLE/DISABLE
FAX CAPABILITY
This menu item toggles FAX capability on and off.
CURRENT FAX
STATUS
Displays current state of FAX capability.
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 VCOM module.
Resetting these performance counters has no effect on the
performancevaluesaccessible viatheSNMP network management
interface.
