#britishtelecom — Public Fediverse posts

It's Longshot Request Friday!

EDIT: Now sorted, thanks!

Does anyone have in their collection an example of an old British Telecom "telemessage" ?

These were greetings telegrams, dictated by phone and sent through the post.

I'm specifically looking for a readable image of the reply instructions that were printed on the reverse side of the page.

For some reason, no one seems to scan the back page when selling these online!

I've attached an example of the front:

#britishTelecom #telemessage

Just over a month and I've tamed all the #trunks (with abundant snake heads at the end), made sure 1500+ #blighters are yeeted (with more trying every day) got inter #PBX #trunk working between on-premises and cloud #FreePBX - just waiting for porting of first analogue number to check this (and CLID presentation) works and then main office one can follow.

Took many late evenings, a lot of research of everything from old #BritishTelecom training manuals to some from Universities in India and the Indian telecom companies, and I've learned a lot more about #SIP even since 2008 when I built the first #VOIP #PBX used at work.

Thankfully #routers seem to handle #SIP over #NAT a lot better than they used to (even got an extension it working over #LTE with #Linphone)

#Telephone set #BritishTelecom 8746 now with replaced 21A microphone insert, working correctly with #Grandstream #HT802 v2 ATA linked to #FreePBX I built on cloud VPS - accepts both #MF (tone) and #LoopDisconnect #dialling (although dialling a full UK mobile number is quite a long process and I had to make sure the timer was at least 4 seconds (or the digits get sent to register before you've dialled any 0 and call fails due to wrong number being sent to #PBX !)

Ring voltage (set to 55V RMS) is strong enough to ring the 4k bell in 8746

So currently this corner of the office looks like its back in 1980s 😁

#VOIP #Telephony

Protip: if you are connecting older #telephones (1980s/1990s) with #BritishTelecom plug to #VOIP via an #ATA (either standalone or that built into your router), beware that many RJ11 to BT socket adaptors now lack the ringing capacitor for the bell wire - some #telephone sets won't ring without it!

If you have a spare #ADSL filter this contains the capacitor and can be used to get your #phone to ring (plug it into BT socket from the ATA and telephone into the BT socket on the filter)

#BritishTelecom 8746 #telephone set from 1982 - 8 prefix means converted for plug and socket working (rather than hardwired to wall!)

Plug and socket connection available from 1981 onwards ( #BT still nationalised then and part of Post Office )

4000 ohm magneto bell (better for parallel working up to max REN of 4, previously magneto bells were 1000 ohms and wired in series in hard wired extension plans). You need capacitor downstream of the line pairs (ADSL filters and /some/ RJ11 to BT socket adaptors contain these), or else bell will not ring correctly - these phones have a third wire for the bell.

Tested it with Openreach analogue circuit - dial works well, Transmitter 21A (electret mic) goosed (distinct odour of overheated Ferranti chip!), may have working 21A somewhere..

Is #BT, #BritishTelecom THE worst UK based company for customer service? My 88 year old mother has been without a landline for months now, she tries to contact BT and I guess we all know how that goes but when she does get through on the rare occasion it's the same old rigmarole every time and "I'll get that sorted for you" Just like "your cheque's in the post" right? Absolutely disgusting customer service.

Does anyone happen to have any documentation for a British Telecom "Tester 420A" ISDN BRI tester.

Also known as the T4200 - seemingly made by Fulcrum Communications in the early 1990s

It's throwing some error codes at me, and I'd really like to know what they mean!

I’ve been for a lunchtime explore, and found these sculptures that have been installed outside the new #BT offices in Bristol.

It seems the artist is Alex Chinneck, and all bar the phonebox appear to be cast in metal. The phonebox is resin, but hollow, with transparent windows…

I rather like them!

I was idly feeding ancient paperwork into the shredder when the size of this phone bill from 2001 took me aback! #WorkingFromHome was an expensive business! £273/month and that seems to be with something called “BT SurfTime”!

Probably #DemonInternet I think.

It's begginning to feel like I'm fighting an uphill struggle with #openreach!! For almost 3 years since we moved into this house, first with #britishtelecom and now with #plusnet we've had the same issue every 10 days, where our Broadband/Hybrid Fibre will just drop and take an age to connect back up. I've lost track how many #openreach Engineers we've had out, and they know exactly what the issue is, but they just don't want to fix it!! It's a long stretch of Aluminium that is causing the 1/2
