One-time Explicit Transfer on the ISDN Line
Explicit Call Transfer (ECT) is an ISDN feature that must be
enabled by your ISDN provider and thus usually is subject
to extra charges. If ECT has not been enabled on your line,
you can program the telephone system to initiate a one-
time explicit call transfer before connecting to two parties.
When you end the connection, the other two parties will be
connected to each other.

With this type of external transfer, both parties are con-
nected to each other over your PBX. This means that both
B channels on your ISDN line remain busy with this con-
nection as long as the parties are connected to each other.

Suspending/Resuming a Call on the ISDN Line
Suspending/Resuming a Call on the ISDN Line
The “Suspend/Resume” feature, also known technically as
Terminal Portability, allows you to suspend an existing con-
nection and resume it at another point on the S
0
bus. The
connection can be resumed at a different ISDN terminal de-
vice (such as an ISDN telephone) that is connected to your
BRI line along with the FRITZ!Box.
You will hear an acknowledgement tone to indicate that the
call has been successfully suspended. If you hear the fail-
ure tone, this may indicate that you made a mistake, or that
the “Suspend/Resume” feature is not enabled on your line.
It is also possible that the parked-call ID you chose is al-
ready in use.
You can resume the suspended call using another ISDN de-
vice on the S
0
bus.
