Number
The object pabxTrunkNumber ranges from 0..31 and specifies

a unique identification for the trunk line.
Descr
Description text for the trunk-line. This object

is for information only and not otherwise being

used by the system.
Slot
This object specifies the number of the physical slot

the trunk-line is leading to.
Unit
This object specifies the physical unit in the slot

specified by pabxTrunkSlot. When there is only one

unit in the slot, the unitnumber has to be set to 0.
Protocol
This object specifies the protocol to be used on the

trunk-line. Currently only dss1 is available.
Enumerations:
  • delete (1)
  • dss1 (2)
Config
This object specifies, whether the trunk line is running

in point-to-point or point-to-multipoint configuration.
Enumerations:
  • point-to-multipoint (1)
  • point-to-point (2)
  • unknown (3)
TeiProc
This object specifies the TEI procedure to be used with the

trunk-line. The procedure may be either  or 

. In the latter case, the TEI value has to be

specified in the object pabxTrunkTeiValue
Enumerations:
  • automatic (1)
  • fixed (2)
TeiValue
This object specifies the TEI value to be used for

fixed TEI configurations and is ignored in automatic

TEI configurations.
CountryCode
This object specifies the country code of the trunk-line.

This information has to be specified in point-to-point

configurations, because the country code has to be skipped

in the destination address of incoming calls in order to

isolate the local extension part.
AreaCode
This object specifies the area code of the trunk-line.

This information has to be specified in point-to-point

configurations, because the area code has to be skipped

in the destination address of incoming calls in order to

isolate the local extension part.
SubscriberNo
This object specifies the subscriber number of the trunk-line.

This information has to be specified in point-to-point

configurations, because the subscriber number has to be skipped

in the destination address of incoming calls in order to

isolate the local extension part.
Extension
This object specifies the extension number of the trunk-line.

This information has to be specified in point-to-point

configurations, because the extension number has to be skipped

in the destination address of incoming calls in order to

isolate the local extension part.

Please note, that this object shall be empty, when connected

to a normal central office line.
Type
The trunk type identifies the purpose of an ISDN interface.

Normal external trunks are identified with type 'external'.

When cascading trunks one side must behave as network side

and, hence, a trunk entry must be created for it, despite

of operating in NT (actually NT or LTS) mode.

This is achieved by creating a trunk of type 'internal'.

Internal trunks are always point to point type interfaces.

Type 'external' is assumed by default.
Enumerations:
  • external (1)
  • internal (2)
L2Mode
The TrunkL2Mode specifies the mode layer 2 is to operate

in. To be able to use leased lines as well as back to back

connections to link two machines, layer 2 mode must be

configurable independently from layer 1 mode.

If mode is set to auto(1), layer 2 mode is derived from

physical configuration of interface (NT/TE). Settings te(2)

and nt(3) force the respective configuration.

By default mode is set to 'auto'.
Enumerations:
  • auto (1)
  • te (2)
  • nt (3)
