OFFICE EXTENDER
SIEMENS GEC COMMUNICATION SYSTEMS PTY LTD
DISA FACILITY (DESIGN TWO THOUSAND PTY LTD REF. No.: SCN 175)
If the first operator PIN is programmed to 9999 (see Operator Manual for Office Extender G/95072 Page 4), the Office
Extender functions as a Direct Inward Station Access (DISA) unit.
When authorised users call into the Extender, they receive a special answer tone followed by internal PABX dial tone. The
caller then dials * 51 followed by their Personal Identification Number (PIN). If the PIN is validated, the caller is then able
to make calls to the Public Switched Telephone Network (PSTN).
At any time dial tone may be re-obtained by pressing * *, which enables follow-on calls to be made without the need to
hang up and log on again. This is also a very useful feature if you miss-dial etc..
To end the session, simply hang up. The Extender will automatically release the lines ready for the next call.
