5.2 Terminal type
For each telephone number of your NT1+2a/b you can select three types of device
type:
Select the device type for a telephone number:
#
#
Speech
#
#
FAX
#
#
Modem
Tip
Default is Speech. Modem works for all combinations. Selection of another type
exclude calls only if they come from or go to ISDN terminals
If you select type facsimile for a telephone device you probably will receive no
tone signalisation from the network (busy, disconnect).
5.3 Emergency terminal
Your NT1+2a/b is normally connected to your local power supply. In this case both
a/b ports and the S/T port are available. In case of local power supply breakdown,
the NT1+2a/b can still work, but in restricted mode only. In that case one device
remains accessible. This could be either a/b1 or a/b2 or one ISDN telephone
connected to the S/T port. You can
select the device for emergency mode at S/T interface:
#
#
select the device for emergency mode at analogue ports a/b1 or a/b2:
#
#
In restricted mode the analogue ports are dynamical (a/b 1 or a/b 2), i.e. the
connection is established to that a/b-port where the receiver is hooked off first.
At this moment the other port is disabled. This is unavoidable, due to the fact
that the exchange provides only a limited wattage.
Note
Default setting for emergency terminal is analogue port.
Don’t forget to select emergency mode on your connected ISDN telephone in this
case.
To avoid blocking emergency terminal selection will be rejected in emergency
state.
