Previously only 0..1 interfaces were allowed, now 0..n interfaces are
allowed. The interface ID is unique for all interfaces, so false
connection can be detected. Other identifiers may be identical at
different interfaces.
User ports use (abstract) ph-socket names that include interface ID:
<interface id>-isdn-<port nr> (e.g. 1-isdn-9100)
<interface id>-pstn-<port nr> (e.g. 1-pstn-8888)
This is a big one:
Startup process was hacked. Several state machines do the startup process now:
- system startup
- PSTN startup
- PSTN restart
- 5 state machines to do multiple port unblocking/blocking
This way there is no lookup required, to get e1inp_line from v5
link and vice versa.
The E1 line is configured whenever it is added to the V5 link. This
happens when entering it in the VTY or loading the config. Also the
signaling channel is opened.
If E1 line is removed from the V5 link, all channels are closed.
