Configuration Settings
· Zero Suppression: Default = HDB3
Selects the method of zero suppression used (HDB3 or AMI).
· Clock Quality: Default = Network
Refer to the Avaya Branch Gateway Installation Manual for full details. This option sets whether the system should try
to take its clock source for call synchronization and signalling from this line. Preference should always be given to using
the clock source from a central office exchange if available by setting at least one exchange line to Network.
· If multiple lines are set as Network, the order in which those lines are used is described in the Avaya Branch
Gateway Installation Manual. If additional lines are available, Fallback can be used to specify a clock source to
use should the Network source not be available.
· Lines from which the clock source should not be taken should be set as Unsuitable.
· If no clock source is available, the system uses its own internal 8KHz clock source.
· In scenarios where several systems are network via digital trunk lines, care must be taken to ensure that all the
systems use the same clock source. The current source being used by a system is reported within the System
Status Application.
· Pulse Metering Bit: Default = A Bit
Sets which bit should be used to indicate the pulse metering signal; A Bit, B Bit or C Bit.
· Line Signaling: Default = CPE
Select either CPE or CO. The CO feature is intended to be used primarily as a testing aid. It allows T1 and E1 lines to
be tested in a back-to-back configuration, using crossover (QSIG) cables.
· The CO feature operates by modifying the way in which incoming calls are disconnected for system configuration
in Brazil and Argentina. In these locales, the CO setting uses Forced-Release instead of Clear-Back to disconnect
incoming calls. The Brazilian Double-Seizure mechanism used to police Collect calls, is also disabled in CO mode.
· Incoming Routing Digits: Default = 4
Sets the number of incoming digits used for incoming call routing.
· CRC Checking: Default = Ticked (On)
Switches CRC on or off.
· Default All Group Settings
Default the MFC Group tab settings.
· Line Signaling Timers:
To edit one of these timers, either double-click on the timer or right-click on a timer and select the action required.
