Quadro Manual I: Installation Guide Step 2: Configuring the Quadro
• 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 PRO-
CEEDING 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 millisec-
onds (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).
The Coding Type drop down list allows you to select between a-law and mu-law coding
types.
The Switch Type is another configuration parameter that depends on the Service Provider.
The Passive Mode checkbox is used to leave the ISDN Layer1 connection in the Slave
mode. When this checkbox is selected, Layer1 remains idle when calls are not available.
When this checkbox is not selected, Quadro keeps its Layer1 always active. This checkbox
enables the Enable TEI Remove Procedure and Permanent TEI Value checkboxes. With
the Enable TEI Remove Procedure checkbox is selected, the trunk will lose the assigned
TEI when entering into passive mode on the Layer 2. With the Permanent TEI Value
checkbox is selected, the trunk will keep the assigned TEI when entering into passive mode
on the Layer 2 or when Quadro detected ISDN link DOWN signal from carrier.
Channel Selection is used to select between the Preferred and Exclusive B channel se-
lection methods. For Preferred channel selection, the CO answers to the call request by
the first available timeslot. With the Exclusive channel selection, the CO should feedback
only by the timeslot asked in the call request.
The Bearer Establishment Procedure drop down list allows selecting the session initia-
tion method on the B channel. One of the following options can be selected for the trans-
mission path completion prior to receipt of a call acceptance indication:
• on channel negotiation at the destination interface
• on progress indication with in-band information
• on call acceptance
The Calling Party Type of Number drop down list allows you to select the type identifying
the origin of call.
