ADSL (Asynchronous Digital Subscriber Line) or ‘Broadband’
When an analogue PSTN telephone line also carries ADSL (Broadband)
signals and it is used by a security system e.g. DualCom, then a Security
ADSL filter MUST be used.
A filter is used to separate the analogue telephone signals from the ADSL
(Broadband) digital data signals because the phone or security system may
be disrupted or completely inhibited if ADSL (Broadband) digital data is
allowed into them from the telephone line.
The CSL CS0730 Security ADSL Filter is designed specifically for use with
security systems. It includes spare terminals to aid wiring that are labelled
‘Pass Through’. This item meets all of the requirements of the British and Euro-
pean telephone and security standards. See Fig 15.
