SD : Were cable customers able to subscribe to the encrypted BBC services in the 1980's?

Rediffusion & later British Relay cabled up many towns (including our own). However, the people that planned these services never envisaged the proliferation of TV & radio services that would appear later down the line. Many of these systems used multicore cables with one channel per cable, & many just had capacity for 4 TV & 4 radio channels. Also most of the cabling on terraced houses was surface going from one house to the next (with them being all council owned). With such capacity, & now wayleave issues these systems had no hope of survival past the early 80s.
