-/* The following set of device service operations are for encapsulation
- protocols that require for reliable datalink semantics. That means:
-
- - before any data is to be submitted the connection must explicitly
- be set up.
- - after the successful set up of the connection is signalled the
- connection is considered to be reliably up.
-
- Auto-dialing ist not compatible with this requirements. Thus, auto-dialing
- is completely bypassed.
-
- It might be possible to implement a (non standardized) datalink protocol
- that provides a reliable data link service while using some auto dialing
- mechanism. Such a protocol would need an auxiliary channel (i.e. user-user-
- signaling on the D-channel) while the B-channel is down.
