Step 2-C: Using ISDN Lines
The basic configuration procedure for Quadro IP PBXs that use ISDN lines is exactly the
same as described in Step 2.
As some ISDN providers require an outgoing MSN to be defined, go to the
Telephony
menu and open the
ISDN Settings
page.
The number of available ISDN trunks is dependent on the type of your Quadro. Quadro2xi
and Quadro4xi have only one ISDN trunk available. Quadro16xi and the special edition of
Quadro4xi have 3 ISDN trunks available.
Fig. I-32: ISDN Trunk Settings page
Before starting the ISDN Trunk configuration, please consult with your ISDN provider ad-
ministrator to receive instructions for which settings are necessary to be configured.
Run the
ISDN Wizard
for each ISDN trunk to make sure that all settings are proper. To
access
ISDN Wizard
, push the appropriate trunk number in the ISDN Trunk Settings table.
The
ISDN Wizard
–
ISDN Settings
allows you to choose the interface type and the con-
nection type of the selected trunk(s).
The
Interface Type
drop down list allows you to select between the User and the Network
interfaces. If the ISDN port of the Quadro is connected to the CO then
User
interface type
should be selected. If the ISDN port of the Quadro is connected to the PBX then
Network
interface type should be selected (in that case Quadro acts as a CO for that PBX).
The
Connection Type
manipulation radio button group allows you to choose the connec-
tion type for the selected trunk(s):
•
PTP (Point to Point)
In case of connection to the CO (
User
interface type is selected on Quadro) choose
this option if only Quadro is connected to the ISDN trunk from CO (no other ISDN de-
vices are connected to the particular ISDN trunk from CO besides the Quadro).
In case of connection to the PBX (
Network
interface type is selected on Quadro)
choose this option if only the PBX is connected to the ISDN trunk from the Quadro (no
other ISDN devices are connected to the particular ISDN trunk from the Quadro).
In both cases, with this selection, Quadro sets the TEI to manually mode assigning the
default value of 0. If needed, that value can be changed later in the
Advanced Set-
tings
page of ISDN Wizard.
•
PTMP (Point to Multi Point)
In case of connection to the CO (
User
interface type is selected on the Quadro)
choose this option if there can be other devices connected to the same ISDN trunk
from CO except the Quadro.
In case of connection to PBX (
Network
interface type is selected on the Quadro)
choose this option if there can be other devices connected to the same ISDN trunk
