[It was standard practise to changeover the POTS from telecom to Saturn as part of the install, which would always get interesting because the Saturn network was TOO good compared to the low-power telecom network.

 

 

TOO good in what way?

 

Telecom had reduced the power on the copper lines over time, which contradicted the spec for deploying voice services but worked in practise so who cared? when you control the network you control the standards and operational practices.

Along rolls Saturn and starts switching over to the shiny new switch which does follow the - higher power - standards, and a few houses were accidentally set on fire somehow. In ISDN land, again the modern standards were followed but did not support a requirement for Full Noise (why would you on a digital circuit?), which meant switching from telecom to clear created some problems for customer PBX's that could not be cheaply resolved - and thus the circuit was switched back and wholesaled instead.

Don't you just love telco tech?
