    Default Re: HT-286 -- intermitent dial tone

    The Sharp fax machine has an REN of 0.7B (not sure what the B stands for, but that's what's on the label).

    The regular phone's REN is 0.1 (Panasonic 5.8GHz cordless).

    I have no idea what the REN limit is of for HT-286; it has a setting for "Onhook Voltage", but the documentation shows 'Low power', and 'High power' and the device simply has a voltage selections for 18, 24, 36, 48, and 51, with 36 being the default. I've tried bumping that all the way up, and it makes no difference.

    It also has an impedance setting, with 600 ohm being the default, and other options for 900, 600 + 2.16uF, 900 + 2.16uF, and a couple more obscure ones for Australia, the UK, and South Africa... I've tried those first 4 settings, and the problem doesn't change.

    In practice, it might not turn out to matter, since it seems I can't fax accrss G711/uLAW anyway...
