Eircom Prequal Line Test

WizZard

Anyone know what criteria the Eircom prequal looks for?

I'm living in Dublin but am originally from Roscommon - Eircom says there are no enabled exchanges there
I want to get broadband at home because there are currently two lines (fax/internet & voice) and the fax line is rarely used for faxes. Using the prequal test on Eircom's site says the line (roscommon) is ok, but how can this be if there are no enabled exchanges? Or is there an exchanges enabled but not publicised yet?
Any help or pointers would be great, thanks.

Thanks Muck, looking into it now

I did a lot of research after my line failed,.
I found out the following:

Eircom main criteria are:

Capacitance to A-Leg
Capacitance to B-Leg

Capacitance acts as a filter, allowing certain frequencies to pass and blocking others. In the case of telephone wires, which were not designed for ADSL use, a high capacitance level can prevent the frequencies used by ADSL from being transmitted properly. Capacitance is affected by cable length, insulation, moisture etc. Line 'noise', which is measure in dB on a logarithmic scale and as a signal/noise ratio, is unrelated to capacitance, which is the important function being tested.

Both the above are measured in Nanofarads and are electrical measurements. I don't know what Eircom's criteria is, but BT accept a reading up to 47 nanofarads, with lower reading i.e. <47 meaning greater suitability for DSL.

Because these are electrical frequencies, it is advisable that you unplug all electrical equipment (caller ID, etc) in order to pass the line test (particularly those that have no independent power source apart from the phone line).

Your no. in Roscommon passes because Eircom (I think) have been told by Comreg to test every line in the country, even those with no exchange upgraded.

Hope this helps,
