Windsor Modem Features

DTMF and Pulse dial

The communicator is capable of both DTMF and Pulse (loop disconnect) dialling of the

programmed telephone numbers. Dialling will only commence in the presence of a valid

proceed indication (dial tone) and may employ Timed Break Recall.

Windsor Modem Features

Timed Break Recall

The Timed Break Recall (“Star Services” in UK) service available on digital exchanges in

many countries is employed at the dial time if no dial tone is detected. This action requests a

clear fresh line from the exchange and overcomes the malicious, or otherwise, blocking of the

telephone line. Timed break recall is not available or necessary in France as the line blocking

is not possible. Timed break recall can be disabled/enabled by using the AT&TBR command.

Windsor Modem Features

Redcare Compatibility

The Windsor Modem can be successfully used on BT Redcare lines due to the filtering out of

the STU low frequency tone at the Windsor Modem telephone line input.

Windsor Modem Features

Blind Dial

Blind dialling (dialling without detecting a dial tone) is a programmable option. If the Windsor

500 is programmed for blind dialling the Windsor modem will go off hook and dial the within 3-

5 seconds (country dependant). If a Windsor modem RX is being used the blind dialling option

is programmed using the AT&BD command.

Windsor Modem Features

Double Calling

When making a call to a panel which is sharing a telephone line with another automatic

answering device, such as a FAX machine, the panel will normally be configured for double

calling. The Windsor modem can instructed, using the ATDR command, to make a second

call to a telephone number when ring back is detected. The second call is made after a delay

of 5 seconds. The number of rings for the first call is programmable using the AT&D3

command. The default is 1 ring. If the panel communicator is a SmartDial Super fitted with

software prior to version 2.7 then the number of rings should be changed to a minimum of 3.
