dial a reserve site in the event of a total failure at the
primary site. The ISDN dialling parameters for the
reserve site are obtained from the adjacent patch to
the currently selected patch (i.e. patch+1).
This function is only active when the C510ip-s is
configured for Backup Master mode.
Audio Source
MENU: Audio Source
Analog
The Audio Source can be set to Analog or AES3.
The AES3 output provides digital audio at a sample
rate of 48KHz with 24 bit audio resolution.
Codec Function
MENU: Codec Function
ISDN Mode
The C510ip-s Codec can operate in 1 of 5
selectable modes :-
IP Mode
ISDN Mode
X21 Mode
Backup Master
Backup Slave
Master X21->IP
Slave X21->IP
Nailed ISDN
ISDN Mode
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 Mode
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
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.
Backup Master X21->IP/ Slave X21->IP
The X.21 port is the primary network interface and
the IP connection 1 is used for backup. The codec at
one end of the X.21 line should be configured as a
Backup Master X21->IP and the other codec should
be configured as a Backup Slave X21->IP. This
prevents both codecs initiating the IP Backup, which
can cause conflict. The automatic IP Backup is
initiated by the 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 Backup Master X21->IP/Slave
X21->IP mode, it is advised that the DCE should carry X.21
termination resistors.
Backup Master IP->ISDN/ Slave IP->ISDN
The IP port is the primary network interface and the
ISDN connection is used for backup. The codec at
one end of the IP connection should be configured
as a Backup Master IP->ISDN and the other codec
should be configured as a Backup Slave IP->ISDN.
This prevents both codecs initiating the ISDN
Backup, which can cause conflict. The automatic
ISDN Backup is initiated by the Master Codec
following 50% of synchronisation errors on the
receive IP Connection. The IP Restore occurs
following 10n seconds of continuous IP integrity, The
Backup Threshold and Restore Time settings can be
modified from these factory defaults using the
Backup Options menu.
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
