QuadroM 32x/8L/26x/12Li/26xi Manual II: Administrator's Guide
The Non Automat checkbox switches to non-automatic
Terminal Endpoint Identifier (TEI) searching and enables
the TEI Address text field that requires a TEI number (digit
values from 0 to 63) for connection establishment between
CO and E1/T1 client. In automatic mode, an E1/T1
connection will be established on the first available TEI,
while in non-automatic mode a specific TEI may be
reserved for the connection. In this case both call partners
need to specify the same TEI in their settings.
The SAPI Value text field requires an additional Service
Access Point Identifier (SAPI) value (digit values from 1 to
62) that is used to support additional interface between
ISDN Layer 2 and Layer 3. Leaving this field empty (default
value), only Call Control and Layer 2 management
procedures will be activated.
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.
In the Network Mode (PBX connected):
•
If Non Automat mode is selected, the same TEI
address should be specified on both sides-
Quadro and PBX.
•
If Automat mode is selected the user on PBX
side will have the opportunity to set any mode
related to TEI assignment in PBX configuration.
This will allow PBX connection to the Quadro
without providing the TEI address from Quadro.
In the User Mode (CO connected) the TEI assignment is
dependent on CO settings:
•
Select Non Automat mode and insert the same
TEI address provided by CO.
•
Select any mode related to TEI assignment if
automat TEI searching mode is selected on CO
side.
Two groups of timers need to be provided. These settings
are adjusted according
requirements.
ISDN L2 Timers:
•
The Excessive Ack. Delay T200 text field configures the period in milliseconds (digit values from 500 to 9999) between transmitted
signaling packet and its acknowledgement received.
•
The Idle Timer T203 text field configures the period in milliseconds (digit values from 1000 to 99999) for E1/T1 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) and indicates the time frame
system is waiting for digit to be dialed and when timer expires, it initiates the call. Timer is not applicable for DMS-100 switch types.
•
The T309 Timer text field requires the value for the T309 timer in milliseconds (digit values from 0 to 90000) responsible for call steadiness
during link disconnection within the period equal to this timer value. If the value in this field is 0, T309 timer will be disabled.
•
The T310 Timer text field requires the value for the T310 timer in milliseconds (digit values from 1000 to 120000) responsible for the
outgoing call steadiness when CALL PROCEEDING is already received from the destination but call confirmation (ALERT, CONNECT,
DISC or PROGRESS) is not yet arrived.
•
The No Answer Disconnect Timer text field requires the value for the No Answer Disconnect Timer (digit values from 0 to 200000) which is
used in certain types of PBXs. The value 0 indicates that the timer is disabled. When time expires, Quadro will play a busy tone towards
the PBX if the call has been disconnected by the peer.
The D Channel Timeslot For Transmit/Receive drop down list contains the timeslots to be selected for signaling data transmit/receive.
