Selecting Use Default outgoing MSN allows you to overwrite the source caller information with the one specified in the Default outgoing MSN text

field when placing outgoing calls toward the CO. The Default outgoing MSN text field requires the Quadro identification number that should be

registered and recognized at the CO for outgoing calls. If this checkbox is enabled but no value is defined in Default outgoing MSN, empty caller

information will be sent to the CO. If this checkbox is disabled, the source caller information will be forwarded to the CO.

If the trunk is configured in the Network mode, the next page of the wizard will be the ISDN Wizard - ISDN Low Level Settings page, otherwise if

the trunk is configured in the User mode, this page will be skipped and the next page will be the ISDN Wizard - L2&L3 Settings page.

The ISDN Wizard - ISDN Low Level Settings page offers a

Power Source selection option. When this option is selected,

the QuadroISDN device will act as a power supply for the ISDN

phones connected to it. Otherwise when this checkbox is not

selected, ISDN phones should have their own power supplies.

Please Note: This checkbox should be always disabled when

the ISDN gateway has a PBX or Telecom connected.

The ISDN Wizard - L2&L3 Settings page offers the following components:

Two groups of timers need to be provided. These settings are adjusted according to the Service Provider requirements.

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, CONNECT, 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.
