4 Operation on a PRI Access
Setting
Protocol
Alerting mode
Clock mode
20
Explanation
Instead of allowing the ARGUS to automatically determine the
protocol (setting: Automatic), it is also possible to manually set the
Layer-3 D-channel protocol. The ARGUS will save the protocol
setting permanently, i.e. it will use this protocol the next time that it
is switched on.
Default setting: Automatic
You can specify whether, for an incoming call on a PRI point-to-
point access, the ARGUS should display only the access number
without extension or the complete number with extension.
If it is set to "Manual", the ARGUS will display the extension (an
incoming call will be signaled. The ARGUS will send the Layer 3
message "Alert" when it accepts the call. The digits of the extension
that have been sent by this point will be displayed.).
With the Manual setting, an incoming call must be
answered within 20 seconds or it will be lost. Furthermore,
you should note that the remote subscriber will not hear a
ringing tone.
If it is set to "Automatically", the ARGUS will only display
the access number without extension or, depending on the
configuration of the access in the exchange, it may not
display the number called at all.
Default setting: Automatic
This parameter sets where the clock will be generated in the case
of a BRI or PRI access. You can either specify that the ARGUS
generates the clock (is Master) or that it is the slave of a clock
generated at the other end (Slave).
Default setting:
NT mode
TE mode
Leased line
This setting will not be saved permanently, rather only applies for
the current measurement.
