answers to the call request by the first available timeslot, while for Exclusive channel selection, CO should feedback only by the timeslot used for
the call request.
The Bearer Establishment Procedure drop down list allows selecting the session initiation method on the B channel. One of the following
possibilities of the transmission path completion prior to receipt of a call acceptance indication can be selected:
• on channel negotiation at the destination interface

The Calling Party Type of Number drop down list allows to select the type identifying the origin of call.
The Called Party Type of Number drop down list allows to select the type identifying the subaddress of the called party of the call.

party's and calling party's number.
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 field has 0
value, system uses either 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 pound sign always cause the call establishment.
The Generate Progress tone on IP checkbox selection will generate the progress tone to IP (H.323 or SIP).
Enable CLIR Service checkbox selection enables Calling Line Identification Restriction (CLIR) service which displays the incoming caller ID only in
case if Presentation Indication is allowed on the remote side. Otherwise, if CLIR service is disabled, caller ID will be unconditionally displayed.
When Alternative Disconnection Mode checkbox is not selected, Quadro will disconnect the call as soon as disconnect message has been
received from the peer, otherwise, when checkbox is selected, Quadro’s user may hear a busy tone when peer has been disconnected.
The B1 Channel and B2 Channel checkboxes enables/disables timeslots for voice transfer. Disabling the timeslot will prevent both incoming and
outgoing calls.
