The fields in the MSN Number column require the MSN
numbers allocated to the Quadro.
Please Note:
At least one MSN number should be defined in
this page. The system displays an error message if the same
MSN number is used twice in this page.
The Route Incoming Call to drop-down lists is used to select
the destination where the incoming call addressed to the certain
MSN number will be routed. Choosing the Routing with
inbound destination number selection will automatically use
the initially dialed number to connect the destination without any
additional dialing. If MSN is disabled on the ISDN Wizard - MSN
Settings page, the ISDN Wizard - Routing Settings page
contains only one Route Incoming Call to drop-down list.
Selecting the Use Default outgoing Caller ID allows you to
overwrite the source caller information with the one specified in
the Default outgoing Caller ID
field when placing outgoing
calls toward the CO. The Default outgoing Caller ID field
requires the caller ID for the outgoing calls from the Quadro
through the ISDN trunk. That number should be registered at
the CO and can be one of the MSNs provided by the CO. If this
checkbox is enabled but no value is defined in the Default
outgoing Caller ID, empty caller information will be sent to the
CO. If this checkbox is disabled, the source caller information
will be forwarded to the CO.

Select the Advanced Settings checkbox if you wish to adjust trunk’s L2 and L3 Settings manually, otherwise leave this checkbox unselected to use
the system default values.
The ISDN Wizard – L2&L3 Settings is used for advanced configuration only and contains L2&L3 Settings. This page only appears when the
Advanced Settings checkbox is selected on the previous page of the wizard. This page contains the following components:
ISDN L2 Timers:
• Excessive Ack. Delay T200 configures the period in milliseconds (numeric values from 500 to 9999) between the transmitted signaling packet
and its acknowledgement received.
• Idle Timer T203 configures the period in milliseconds (numeric values from 1000 to 99999) for the ISDN client idle timeout.
ISDN L3 Timers:
• The T302 Timer text field requires the value for the T302
timer in milliseconds (digit values from 0 to 15000). It
indicates that the time frame system is waiting for a digit to
be dialed. When the timer expires, it initiates the call.
• T309 Timer requires
the value for the T309 timer in
milliseconds (numeric values from 0 to 90000). It is
responsible for call steadiness during link disconnection
within the period equal to this timer value. If the value in
this field is zero (0), the T309 timer will be disabled.
• T310 Timer
requires the value for the T310 timer in
milliseconds (numeric values from 1000 to 120000). It is
responsible for the outgoing call steadiness when CALL
PROCEEDING is already received from the destination but
call confirmation (ALERT, CONNE
CT, DISC or
PROGRESS) has not yet arrived.
• Alert Guard Timeout
requires the value for the Alert
Guard Timer in milliseconds (numeric values from 0 to 500)
between CALL PROC and ALERT messages. Alert Guard
Timer it is used when Quadro is connected to a slow ISDN-
PBX.
Recommended values are:
- fast connection (0ms);
- normal (150ms), default;
- slow ISDN-PBX (350ms);
- very slow ISDN-PBX (500ms).
