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.
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.
Please Note: The Passive Mode , Enable TEI Remove Procedure and Permanent TEI Value checkboxes are present only for connection types
different from PTP (Point to Point) selected on the first page of ISDN Wizard. If PTP (Point to Point) connection type is selected on the first page of
the ISDN Wizard, these three checkboxes are replaced with a
TEI Address text field that requires the channel number (digit values from 0 to 63) for
connection establishment between the CO and the ISDN client.
Channel Selection is used to select between the Preferred and Exclusive B channel selection 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 initiation method on the B channel. One of the following options
can be selected for the transmission 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.
The Called Party Type of Number drop down list allows you to select the type identifying the subaddress of the called party of the call.
The Called Party Numbering Plan and Calling Party Numbering Plan drop down lists correspondingly indicate the numbering plan of the called
party's and calling party's number.
The Incoming Called Digits Size text field indicates the number of received digits (in a range from 0 to 255) required to establish a call. When this
field has a “0” value, the system uses either the timeout defined in the T302 field or the Sending Complete Information element messages to
establish a call. Independent on the value in this field, Sending Complete Information element and the pound sign always result in call
establishment.
The
Generate Progress tone on IP checkbox selection will generate the progress tone to IP.
When Generate Progress Tone to PSTN/PBX checkbox is selected, Quadro generates ring tones to callers during ISDN call dialing. This feature is
mainly applicable to 2-stage dialing mode.
Enable CLIR Service checkbox selection enables Calling Line Identification Restriction (CLIR) service which displays the incoming caller ID only if
Presentation Indication is allowed on the remote side. Otherwise, if CLIR service is disabled, caller ID will be unconditionally displayed.
When the Alternative Disconnection Mode checkbox is not selected, Quadro will disconnect the call as soon as the disconnect message has been
received from the peer. When the checkbox is selected, Quadro’s user may hear a busy tone when peer has been disconnected.
P-Asserted-Identity:
The Disable P-Asserted-Identity radio button disables the P-Asserted-Identity feature for both incoming and outgoing calls.
