C
ONFIG
Provides diagnostic tools for suspected problems; under normal operation,
users do not configure the VoFR devices.
D
EVICE
Read Security: 5
Identifies the VoFR device on the VCOM Module. VoFR devices are num-
bered 1 through 32.
S
TATE
Write Security: 3; Read Security: 5
Controls the configuration state of the individual VoFR device. The
VCOM Module determines the initial configuration state of each device.
ATLAS uses this configuration information to determine which VoFR
devices are functional and may be used; which are defective and should not
be used; or which are not present on the module and should not be used.
Users who suspect an individual VoFR device of improper operation can
manually disable that device to prevent ATLAS from attempting to use it.
The possible states are defined below.
D
EFERRED
Devices which fail built-in testing are automatically marked as Deferred, in-
dicating that the ATLAS 550 declines to use the device.
A
VAILABLE
The device is properly functioning and can be used when required. The
ATLAS 550 automatically marks devices that pass built-in testing as Avail-
able.
D
ISABLED
Marking a device as Disabled prevents the ATLAS 550 from attempting to
use it. You can mark a device currently in use as disabled without disturbing
the connection, but the device will not be eligible for use in future calls until
you re-mark it as Available. You might want to do this if you suspect that a
particular device is malfunctioning and do not want any calls routed to it.
TEST
The
T
EST
menu requires no user action during normal operation. However,
the ATLAS 550 and the VCOM Module make various
T
EST
performance
measurements available to the user to gain insight into the low-level func-
tioning of the VCOM Module. If a malfunction is suspected on the VCOM
module, ADTRAN service personnel can use this menu to locate the prob-
lem.
This menu is documented here in the interest of completeness. The values
automatically reset each time the VCOM Module is installed into the the
ATLAS 550 chassis. These values are also cleared whenever the ATLAS
controller is rebooted.
