· 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 Sub Type: Default = T1
Set to T1 for a T1 line. For PRI see Line Form (US PRI) . If set to ETSI, QSIG A or QSIG B see Line (E1) .
· Channel Allocation: Default = 24 | 1
The order, 24 to 1 or 1 to 24, in which channels are used.
· 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.
· 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.
· 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.
· Haul Length: Default = 0-115 feet
Sets the line length to a specific distance.
· Channel Unit: Default = Foreign Exchange
This field should be set to match the channel signaling equipment provided by the Central Office. The options are
Foreign Exchange, Special Access or Normal.
· CRC Checking: Default = On
Turns CRC on or off.
· Line Signaling: Default = CPE
This field affects T1 channels set to Loop-Start or Ground-Start. The field can be set to either CPE (Customer Premises
Equipment) or CO (Central Office). This field should normally be left at its default of CPE. The setting CO is normally
only used in lab back-to-back testing.
· Incoming Routing Digits: Default=0 (present call immediately)
Sets the number of routing digits expected on incoming calls. This allows the line to present the call to the system once
the expected digits have been received rather than waiting for the digits timeout to expire. This field only affects T1
line channels set to E&M Tie, E&M DID, E&M Switched 56K and Direct Inward Dial.
