Andreas Eversberg 2dca6472b1 Add option to enable PSTN datalink before startup 
This is the default behaviour now. PSTN datalink can be established
before the system startup has been completed.

osmo-v5 - Osmocom implementation of ETSI/ITU V5 interface

This is a repository containing code implementing the ETSI/ITU V5 interface as specified in ITU-T G.964 + G.965.

V5 is an interface spoken between digital telephone exchange and its [remote] access network (multiplexers + concentrators of subscriber access lines).

For some general intro into V5, you might find the following OsmoDevCall recording interesting: https://media.ccc.de/v/osmodevcall-20211228-laforge-retro-isdn-v5

Initial development was done just using the spec as reference; from 09/2022 onwards a Nokia EKSOS N20 became the primary target. The code has been uses successfully against Nokia EKSOS N20 and Siemens Fastlink.
