I shall be happy to be corrected if I am wrong but my understanding is that a number of manufacturers will make any one product for
Openreach -- something to do with not showing favouritism and not being dependant on only one supplier.
One of the suppliers to
Openreach is
Pressac, another is
LPT Technology, another is . . .
I've just picked up a sealed package from within my grotto. The label attached to the front reads --
Item Code: 049579
Desc: VDSL Face Plate to Assist NTE4
Qty: 1
UOI: EACH
Contract: B8003750
Date of Manuf: 02/12
The filter contained therein is marked on the front (moulded lettering) --
Openreach
a BT Group Business BT
and on the rear (printed) --
LPT Technology
I would not be surprised to discover that those with a printed logo, etc, on the front are made by one of the other manufacturers and not
LPT Technology.
The circuitry, components used, etc, will be identical. I suspect there with be a
SIN in which the device is described.
