FEATURES
MODEM SWITCH will automatically detect an incoming Data Modem call and then connect it to your Modem based device.
MODEM SWITCH is designed to operate on an existing Voice or Fax telephone Line, overcoming the need for a separate dedicated line.
MODEM SWITCH can also be used with your PABX, Commander or other Multi-Line telephone system (usually requires technical installation when connected to Multi-Line systems).
MODEM SWITCH is ideal for businesses which requires infrequent dial in Modem access and results in a considerable saving over the $30.00 per month, normally associated with business telephone line rental.

DESCRIPTION
MODEM SWITCH
is a highly intelligent device that is pre-programmed to operate with THREE SEPARATE Dial In Access Operating methods, allowing you the flexibility to customize your Modem Dial In method (see details below).
MODEM SWITCH also provides Barge-In protection to ensure that the attached MODEM and OTHER DEVICE(s) cannot interrupt each other during a telephone call.
MODEM SWITCH is designed for EASY USER INSTALLATION where it is used on a fax line or a line where only one telephone socket is used. Installations on PABX/Multi Line Systems or voice lines where more than one telephone socket are used will require technical installation.

THREE OPERATING METHODS
TRADITIONAL DIAL IN MODEM ACCESS METHOD
MODEM SWITCH
will answer ALL incoming calls FIRST, briefly “listen” to this call for Modem Calling Tones (1300Hz CNG Tones) and then connect the call to your Modem or Other Device(s).
ALTERNATIVE DIAL IN MODEM ACCESS METHOD
A small number of Modem Devices may not send Modem Calling Tones when dialling out. In this situation, additional digits are added to the destination telephone number. These
DTMF digits are used to command Modem Switch to connect the incoming call to the attached Modem Device.
FAXSTREAM DUET DIAL IN MODEM ACCESS METHOD
MODEM SWITCH
also provides for those customers who wish to use the new Telstra FaxStream Duet service, (now or in the future) where a new additional telephone number, specifically for use as your Modem number, is added to your telephone line. This service is available from Telstra at a cost of $6.00 per month.

MODEM SWITCH is completely compatible with the use of ADSL on the same telephone line. A Dip Switch setting is provided, which if enabled, will allow the Calling Number Display (CLI) information to be passed through to your CLI Reader device, before MODEM SWITCH answers the call.
MODEM SWITCH is completely compatible with the use of ADSL on the same telephone line, PROVIDING A HIGH QUALITY CENTRAL ADSL FILTER IS USED. This filter should be connected between the LINE port of MODEM SWITCH and the telephone socket that it is attached to.
Note - Basic ADSL filters as suplied for use with telephones ARE NOT ADEQUATE.
We recommend the use of the C10 BRAND CENTRAL ADSL FILTER. These filters can be ordered ON LINE, by telephone (ph 07 5596 5128) or can be purchased from your local TELSTRA RETAIL OUTLET at a cost of $35.00.
