Usability
· Mergeable: These settings are not mergeable. Changes to these settings will require a reboot of the system.
Configuration Settings
· 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.
· Line Number
This parameter is not configurable; it is allocated by the system.
· Line Sub Type: Default = ETSI
Select to match the particular line type provided by the line provider.
· S-Bus:
IP500 BRI daughter cards can be configured for So (S-Bus) operation for connection to ISDN terminal devices. Note
that this requires the addition of terminating resistors at both the system and remote ends, and the use of a suitable
cross-over cable. For full details refer to the Avaya Branch Gateway Installation manual.
· 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.
· Telephone Number:
Used to remember the external telephone number of this line to assist with loop-back testing. For information only.
· Incoming Group ID: Default = 0, Range 0 to 99999.
The Incoming Group ID to which a line belongs is used to match it to incoming call routes in the system configuration.
The matching incoming call route is then used to route incoming calls. The same ID can be used for multiple lines.
· Outgoing Group ID: Default = 0, Range 0 to 99999.
Short codes that specify a number to dial also specify the line group to be used. The system will then seize a line with
a matching Outgoing Group ID. The same ID can be used for multiple lines.
· Prefix: Default = Blank.
The prefix is used in the following ways:
· For incoming calls
The ISDN messaging tags indicates the call type (National, International or Unknown). If the call type is unknown,
then the number in the Prefix field is added to the ICLID.
· For outgoing calls
The prefix is not stripped, therefore any prefixes not suitable for external line presentation should be stripped using
short codes.
· National Prefix: Default = 0
This indicates the digits to be prefixed to a incoming national call. When a number is presented from ISDN as a
"national number" this prefix is added. For example 1923000000 is converted to 01923000000.
· International Prefix: Default = 00
This indicates the digits to be prefixed to an incoming international call. When a number is presented from ISDN as an
"international number" this prefix is added. For example 441923000000 is converted to 00441923000000.
· TEI: Default = 0
The Terminal Equipment Identifier. Used to identify each device connected to a particular ISDN line. For Point-to-Point
lines this is 0. It can also be 0 on a Point to Multipoint line, however if multiple devices are sharing a Point-to-Multipoint
line it should be set to 127 which results in the exchange allocating the TEI's to be used.
· Number of Channels: Default = 2. Range = 0 to 2.
Defines the number of operational channels that are available on this line.
· Outgoing Channels: Default = 2. Range = 0 to 2.
This defines the number of channels available, on this line, for outgoing calls. This should normally be the same as
Number of Channels field, but can be reduced to ensure incoming calls cannot be blocked by outgoing calls.
