Does anyone have or know where to get System X information.
I have lots of other Telco books to exchange.Apologise for the very late answer.
Worked with GPT’s System-X back in 1980/1990s. Worked with DSS, DSSS, PUS / POPUS, CAS, MTS, OMS, etc..System-X is now consigned to Switch history.

Just an add on to System-X.
Look at Telent. They now look at the leftovers of the System-X estate in terms of development for customers that still have System-X equipmemt.

Just an add on to this thread.
I remember working with a lot of Resource Management documentation that helped with MML – Man Machine Language – commands.
I remember working with the following systems (and subsystems):
PUS – Processor
DSS – Switch
DSSS – Concentrator
SIS – Signalling Interworking
MCS – Maintenance Control system
CPS – Call processing subsystem
CAS – Call Accounting
NSS – Network Synch.Code used was (BT)Coral66. DCD was used with the data. Numerous BA / BB / etc.. “cards” were used with the DCD.
