ISDN Mode
The C510xr/C520xr Codec can operate in 1 of 5
selectable modes :-
ISDN Mode
X21 Mode
Backup Master
Backup Slave
Nailed ISDN
ISDN M de
The ISDN ports are the primary network interface
and the X.21 port is the secondary network
interface. If there are no ISDN calls connected, the
audio will be routed to the X.21 port by default.
X21 M de
The codec will only route audio to the X.21 port, and
will effectively ignore the ISDN ports. The ISDN
ports will still be capable of making and receiving
ISDN calls, however the audio will not be routed
through to the ISDN connections.
Backup Master / Slave
The X.21 port is the primary network interface and
the ISDN ports are used for backup. The codec at
Page 11

one end of the X.21 line should be configured as a
Backup Master and the other codec should be
configured as a Backup Slave. This prevents both
codecs initiating the ISDN Backup, which can cause
a call conflict. The automatic ISDN Backup is
initiated by the Backup Master Codec following 50%
of synchronisation errors on the X.21 line. The X.21
Restore occurs following 10 seconds of continuous
error free, test data transmissions on the X.21 line.
The Backup Threshold and Restore Time settings
can be modified from these factory defaults using
the Backup Options menu.
NOTE: When operating in ISDN Backup Master/Slave mode,
it is advised that the DCE should carry X.21 termination
resistors.
Nailed ISDN
Nailed ISDN lines are available in some countries
for fixed point-to-point digital Transmissions. The
DIAL and HANG buttons are not required in this
mode and are therefore disabled. The audio format
used is defined within the ISDN Options menu.
The Nailed ISDN feature supports connectivity with
itachi Ta's in the following audio modes:

Alarm Signal
The C510xr / C520xr provides a set of alarm relay
contacts with a minimum of 0.5 second duration.
These relay contacts are provided on the auxiliary
data port connector.
For connection information, please refer to the pin-
out detail of the auxiliary data connector. The
maximum voltage is 50V.
Rem te Trigger
The Remote Trigger input operates by connecting
the Remote Trigger (Pin 9 of auxiliary data
connector) to GND and holding the connection. This
instructs the Codec to dial the ISDN using the
current selected patch configuration. To hangup the
ISDN call, disconnect the pin from GND.
The Remote Trigger can be Wire-Or connected for
multiple remote trigger access, e.g. several studios
sharing a single C510xr/C520xr unit.
Remote Trigger Input - Do Not Connect to Voltage
Outputs.
