· Mergeable: These settings are not mergeable. Changes to these settings will require a reboot of the system.
Configuration Settings
· Line Number:
Allocated by the system.
· Card/Module:
Indicates the card slot or expansion module being used for the trunk device providing the line. 1 to 4 match the slots
on the front of the control unit from left to right. Expansion modules are numbered from 5 upwards, for example
trunks on the module in Expansion Port 1 are shown as 5.
· Port:
Indicates the port on the Card/Module above to which the configuration settings relate.
· Network Type: Default = Public.
This option is available if Restrict Network Interconnect (System | Telephony | Telephony ) is enabled. It
allows the trunk to be set as either Public or Private. The system will return number unobtainable indication to any
attempt to connect a call on a Private trunk to a Public trunk or vice versa. This restriction includes transfers,
forwarding and conference calls.
· Line SubType: Default = PRI
Set to PRI. If set to T1 see Line Form (T1) . If set to ETSI, ETSI CHI, QSIG A or QSIG B see Line (E1) .
· Channel Allocation: Default = 23 | 1
The order, 23 to 1 or 1 to 23, in which channels are used.
· Switch Type: Default = NI2
Options 4ESS, 5ESS, DMS100 and NI2.
· Provider: Default = Local Telco
Select the PSTN service provider (AT&T, Sprint, WorldCom or Local Telco).
· Prefix: Default = Blank
Enter the number to prefix to all incoming numbers for callback. This is useful if all users must dial a prefix to access
an outside line. The prefix is automatically placed in front of all incoming numbers so that users can dial the number
back.
· Add 'Not-end-to-end ISDN' Information Element: Default = Never*.
Sets whether the optional 'Not end-to-end ISDN' information element should be added to outgoing calls on the line.
The options are Never, Always or POTS (only if the call was originated by an analog extension). *The default is
Never except for the following locales; for Italy the default is POTS, for New Zealand the default is Always.
· Send Redirecting Number: Default = Off.
This option can be used on ISDN trunks where the redirecting service is supported by the trunk provider. Where
supported, on twinned calls the caller ID of the original call is passed through to the twinning destination. This option is
only used for twinned calls.
· Send Names:
This option is available when the Switch Type above is set to DMS100. If set, names are sent in the display field.
The Z shortcode character can be used to specify the name to be used.
· Names Length:
Set the allowable length for names, up to 15 characters, when Send Names is set above.
· Test Number:
Used to remember the external telephone number of this line to assist with loop-back testing. For information only.
· Framing: Default = ESF
Selects the type of signal framing used (ESF or D4).
· Zero Suppression: Default = B8ZS
Selects the method of zero suppression used (B8ZS or AMI ZCS).
· 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.
