Thank you for making those pictures available for viewing. I am very surprised that the engineer did not remove the
Bell Set No 26, as it really is not appropriate for today's telephone circuitry.
Pictures 1 & 2 show a
Block Terminal No 52A, which was nominally installed between the years 1959 - 81. I expect that to have been replaced by a
Block Terminal No 80A.
Now as all the wiring and fittings
before the
NTE5/A belong to
Openreach, we would not advise you to make any modifications. However, I can see no reason why I should not mention the two possible adjustments that
I would make, if that wiring existed in my own home. Please note that I have made an extensive study of
GPO,
BT &
OR techniques employed over the years and am able to make necessary adjustments, as if performed by such a relevant engineer.
*** Either ***
1) With the
Line Jack Unit No 2/3A (pictures 3 & 4) and the
Bell Set No 26 (pictures 10, 11 & 12) unwanted & redundant, I would completely rewire with
CW1308 specification cable from the new
Block Terminal No 80A directly to the new
NTE5/A socket. To finish the job, I would then fit an
ADSL V1.0 SSFP, thus doing away with a dangly microfilter.

2) Within the
Bell Set No 26 (pictures 10, 11 & 12), disconnect the four wires (blue, brown, green & orange) of both cables from the terminals and then connect each like coloured wire from one cable to the like coloured wire from the other cable with gel-crimps. Again at the
NTE5/A, to finish the job, I would then fit an
ADSL V1.0 SSFP, thus doing away with a dangly microfilter.
If you would like further thoughts on your current situation, please show pictures of the internals of the new components fitted by the
Openreach engineer and of the cable route from the junction with the drop-cable, to the bell set, to the
LJU2/3A socket, finally to the
NTE5/A.
