MODULES (VCOM-X) > STATISTICS > VCOM DROP
Read security: 5
Counter that measures each frame dropped or discarded by ATLAS 550 during communication with the
ATLAS 550 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 550 system.
MODULES (VCOM-X) > STATISTICS > 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.
MODULES (VCOM-X) > STATISTICS > RELOADS
Write security: 4; Read security: 5
Number of times since module reboot that this device has been reloaded due to a failure.
MODULES MENU (32 CHANNEL ADPCM RESOURCE MODULE)
The ATLAS 550 system controller automatically detects the presence of the 32 Channel ADPCM Resource
Module when it is installed in the system (listed as ADPCM-32). To see the menus for the 32 Channel
ADPCM Resource Module via the terminal menu, use the arrow keys to scroll to the MODULES menu and
press <Enter> to access the module choices. Refer to the 32 Channel ADPCM Resource Module Quick
Start Guide for a menu tree containing a complete listing of menus.
MODULES (ADPCM-32) > INFO
Read security: 5
Provides information about the module part number, serial number and assembly revision.
MODULES (ADPCM-32) > INFO > PART NUMBER
Read security: 5
Displays the part number of the module.
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 performance values accessible
via the SNMP network management interface.
