The DSCP value for the Telephony Gateway uses all 8 bits in the IP
header but DSCP values are calculated using only the first 6 bits. This will
affect the decimal value entered for the two call modes available. You will
need to multiply the DSCP tag that you wish to apply by 4 (to shift the
value to the upper 6 bits) The DSCP tag value being multiplied must be
less than 64.
For example, if you would like the DSCP tag for in-call to be 46, multiply
it by 4, which will give you the value 184. Enter this number into the
DSCP field in the Telephony Gateway.
Default DSCP settings will not mark traffic for prioritized handling under
normal circumstances. Please consider changing these values based on the
recommended QoS settings from your network hardware manufacturer to
achieve prioritization for your voice traffic.
Inactivity Timeout (min)
: Set the number of minutes the administrative module can
be left unattended before the system closes it. This number can be from 1 to 100. If
it is set to zero (0), the administrative module will not close due to inactivity.
System Locked
: This option is used to take the system down for maintenance. The
default entry is
No
. Set it at
Yes
to prevent any new calls from starting. Return to
No
to restore normal operation.
Maintenance Lock
: The system automatically sets this option to
Yes
after certain
maintenance activities that require reset, and certain alarms that cause the system to
be inoperable. Such maintenance activities are indicated in this list with an arrow
bullet. Maintenance Lock prevents any new calls from starting. Note that the
administrator cannot change this option. It is automatically set by the system. Reset
the system at exit to clear Maintenance Lock.
The NetLink Telephony Gateway monitors the condition of any NetLink
SVP Server(s) on the system. In a single NetLink SVP Server system,
when the SVP Server goes into Maintenance Lock, the Telephony
Gateway will also lock and set an alarm. No new calls will be allowed but
calls in progress will not be affected.
In multiple SVP Server systems, when one SVP Server goes into
Maintenance Lock, it sends a message to the Telephony Gateway(s) which
will stop using the locked SVP Server. It may take up to 30 seconds for the
message to reach the Telephony Gateway. If all SVP Servers lock, then the
Telephony Gateway will also lock and set an alarm. No new calls will be
allowed but calls in progress will not be affected.
Checkout all phones
: This command is used to upgrade all handsets without having
to reset the Gateway. It forces all the handsets on the system to check in with the
Gateway. In doing so, they will check their current software version vs. the version
stored on the TFTP server and download if needed. Any handsets in a call will
perform their checkout after the call is complete.
Reset System
: If this option is selected, you will be prompted to reset this NetLink
Telephony Gateway.
