This afternoon my Mother's Assistance Alarm unit suddenly started bleeping. Picking up a phone revealed a 'dead' line, i.e. no Dialling Tone. However the Internet connection is fine. Mysterious! I called Plusnet and spoke to an agent who checked with Openreach and found that there was a line fault. As my Mother's Assistance Pendant is useless without the phone-line, PN raised the matter as a 'Welfare Issue' so, hopefully, it will be resolved pretty quickly. As things are it means that I cannot safely leave the house as Mum could, perhaps fall etc. and be unable to summon Assistance. As the assistance alarm provider's agent said, such a facility is a 'Lifeline'.
