Can I have another telephone extension running from the splitter/front plate or ADSL filter? Print this page   Yes, additional telephone equipment may be connected using an approved telephone two-way adaptor. If you have BT Yahoo! Broadband with modem, the two-way adaptor has to be fitted into the ADSL filter, and not the wall socket. If you have an 'Engineer Assisted' product, the two-way adaptor can be fitted directly on the 'splitter/front plate'.   Is this enough information? Great!
