## Fax Extension

## Definition

A fax that is connected to ASB 150 02 via an analogue extension can be specfied as fax extension.

## Use

A connected fax can be specified quite easily: All relevant commands for analogue extensions are valid, but the execution of the features in the following table are restricted.

## Operation

To guarantee the smooth operation with ISDN fax machines, which do not always support the Group3 protocol two different types of fax settings are offered:

1. Group3 fax (for analog fax machines)
2. fax (for analog and ISDN fax machines)

Once an analogue extension interface is defined as fax extension, the following features are restricted:

| feature name | restrictions
extension facilities
1 | conference | not allowed to be a member in a conf.
2 | call back | not allowed to initiate call back to a fax extension
3 | break-in (intrusion) | not allowed to initiate break-in on a fax extension
4 | camp-on | initiation of camp-on without camp-on tone *
5 | diversion direct (internal & external) | not allowed to a fax extension **
6 | diversion on no reply (internal & external) | not allowed to a fax extension **
7 | diversion on busy (internal & external) | not allowed to a fax extension **
8 | follow me | not allowed to a fax extension **
trunk facilities
1 | reroute position at day | not valid for fax extensions ***
2 | reroute position at night | not valid for fax extensions ***
3 | common voice announcement at day | not valid for fax extensions ****
4 | common voice announcement at night | not valid for fax extensions ****
5 | busy voice announcement at day | not valid for fax extensions ****
6 | busy voice announcement at night | not valid for fax extensions ****

* |  | It is only possible to make a camp on to a fax extension via an extension only through a DID or transferred call, a diverted call cannot be camped on.

** |  | Call forwarding is allowed, if the call comes from another fax extension.

*** |  | Only valid, if reroute position is also a fax extension

**** |  | We recommend not to program this voice announcement. If the voice announcements are programmed they will be played even if there is just a fax coming in.

## Capacity / Limitations

Each analogue extension can be configured as fax extension.

Programming an individual as fax extension overrides the command "1032 Trunk impedance adaption". This command is normally used to state whether or not the automatic trunk impedance adaption (ATIA) has to be used.

## Programming

This command can only be accessed via BMS:

0162 |  | Terminal type

## Equipment

The function is supported by ASB 150 02 R9 or higher system releases.

In order to have access to the function, the proper licensing concept has to be used, see Facility Description – General (155 34-ASB 150 02 Uen), chapter ASB150 02 Licensing
