Generally speaking, if Ma Bell adopted a
technology, it was probably
pretty durable. =A0Modular plugs excepted.
Real Western Electric modular plugs are actually very good and can
withstand a zillion insert cycles.
But there hasn't been a real WE modular plug made in a very long time...
I do not like the design of the latch on the modular plugs, or indeed the
UK telehpone plug (Plug 431A, ec). The latck has the annoying habit of
getting snagged on the cable when you're untnagling the latter and
breaking off.
I ahev seen UK typve plugs with the top of the latch forrmed int oa
flexible lookp that joins onto the plug body to prevent this problem.
Whether modular plugs are mad like this I don't know, I've never seen one.
