Shots of CB1 in action, of the new crossbar and the changeover ceremony.

    And in 2018, my phone line was cut and removed from the property, as the copper wire network was to be decommissioned, and on a day the copper was removed, fibre optic installed and never again will dial tone be heard, 2 sounds never to be heard again, dial tone and dial up on a 56k modem, RIP telephones, thank you for your service..

    That's because back then people mattered so there was a thing called civility which we have lost today. Today money and profits come first. People are just a necessary evil, to be treated as disposable items like all those fuses they pull with no regard to them. Corporate ethics back then were not damaged by the single minded profiteering matra installed by Thatcher who believed things would be much better if profits came before people.

    This exchange had a maximum of 10,000 phones connected to it. You can tell it by looking at the size of the new permutation racks, or more precisely, by looking at the power supply current meter, which shows 180 Ampere of current. Our analogue phone lines are powered by -48 V DC, with a line current of 20 mA, or 0.02 A each. So, with 180 Amps, 9000 phones are connected concurrently. In many places, the limit of 10K phone terminals max has been a lingering problem until electromechanical exchanges have been replaced with the actual computerised types, which uses in-band DMTF (multi-tone) for dialing, and are capable of carrying caller ID information and later, ADSL for data and Internet. Very slowly the PSTN are being replaced by their fully digital counterparts. This change impacts the customers negatively, as all telephone terminals in homes must be replaced. In certain cases, the terminal needs electrical power. The wisdom, at this point, should be to replace this "last mile" directly with a fiber optic.

    Rayo, your calculation is clearly nonsense. not everybody will be calling at once - in fact they can't, because phone companies limit the number of trunks to what's actually needed. A general rule of thumb valid in western counties is that telephone usage peaks at 1/10th - so a drain of 180 amps means a total of 100,000 phones, not 10,000, assuming your 20 mA per phone is valid.. However, other equipment usually found in telephone exchanges adds to the current.

    As a 40 year old, obviously I've never experienced this, but my goodness we came a long way and I must say it's refreshing to see this even though I wasn't around then. The changeover from manual to automatic exchange was really a very big project, no margin for error, even though there must have been a fallback. But credit to those who were involved in this. I wonder those telephone operators, the changeover to be honest meant job losses, I wonder how they transitioned to another job or changed careers.

    Only a few years ago AT&T abandoned the buried copper lines in my rear yard and installed fiber optic lines in the front, & into my living room. Never thought I would see a fiber optic line into my single family home. That is amazing. I think by 1970 only a few long distance calls still used an operator in the USA. Now, nearly all that mechanical equipment is history. I worked with a man who had been employed as a telephone operator. We were just starting off at a rather low paying government job. I asked him why he quit a job paying substantially more, and was surprised to hear him say that he couldn't take all the verbal abuse from customers. He said it gradually got to him, so he quit.

    the out of sync soundtrack makes this ridiculously (hetero)sexist remark combine with shots of the male ('non-attractive') workers - but this was the era of everything being viewed through a male and straight prism - therefore 'attractive' can ONLY mean young 'dolly birds'. So limited, so fucking sad - such a relief to realise how far we have come from those bleak, dingy, blinkered and male-outlook dominated days - where a factual information film about telecommunications has to fall back to the trope of saying how sexually attractive are the (only) women who appear in it.

    This film is dated 1970. It says the exchange is the first to get crossbar. But the relays shown are the old fashioned BPO 3000-type that date back to 1950 or earlier that require periodic adjustment, not the maintenance free relays that other administrations used with crossbar. Bad film editing or was the BPO a really old fashioned government department? The second, actually - In Australia our then old fashioned government department phone company APO started installing crossbar (with "modern" maintenance free relays) back in 1960 - which was years and years after the Americans. they showed ceramic formed wire wound resistors of a design introduced about 1900 too.

    The commentary says "for forty years all calls including local ones had to be connected by an operator". Surely most/all exchanges would have been automated with Strowger in the 20s for local calls, with operators being used for trunk calls until STD. According to a Wikipedia article the UK started STD on 5 December 1958 but doesn't say when the roll-out was completed but 1970 when this film was made seems reasonable.
