If it's Zen you are staying with as an FTTC ISP, then the install will be for 'modem only'. Dependant on who comes to do the work, some tests of sync should be made, and a pair quality test made if a fully fledged OR bod.
Why not remove the faceplate filter in the morning, that way you'll get one fitted, and have one as a spare as you said ? A good chance it'll be an MK3 as well.
Yup, staying with Zen. No reason not to.
Had OR out not that long ago for an intermittently cracking line - apparently it's the "perfect pair", apart from the noise, that he only heard once, whilst not in the test socket, so off he went. (I've heard it in the test socket!)
Was an oldish guy too, which in my quite broad experience, means a good one.
I'm more interested in getting the modem, as the filters can be had for not much money, and the mk3 is meant to hit synch speed to the benefit of stability. I'm also "working from home" so really need to stay connected whilst I can...
Right now the crackling has gone, maybe someone nudged the pair in the PCP. There's a quiet hum, but it's not affecting my ADSL synch speeds.
I was more curious to know what I should expect, so he/she doesn't leave without have done everything they're meant to do.
Almost 5 years to the date from FTTC commercial availability. What a wait..!
