QXFXO4/QXISDN4/QXE1T1/QXFXS24 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, QX
will disconnect the call as soon as disconnect message has been
received from the peer, otherwise, when checkbox is selected, QX'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- QX 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 QX without providing the TEI address
from QX.
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 to the Service Provider 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
D Channel Timeslot For Transmit/Receive
drop down list contains the timeslots to be selected for signaling data transmit/receive.
