A new ISDN/PSTN Network Service can be defined even if no RTM
ISDN card is installed in the system but only via the ISDN/PSTN
Network Service ->Add New Service dialog box.
The Fast Configuration Wizard's ISDN/PSTN configuration sequence
begins with the ISDN/PSTN dialog box.
17 Define the following parameters:
Field
Network Service
Name
Span Type
Service Type
18 Click Next.
Description
Specify the service provider's (carrier) name or any
other name you choose, using up to 20 characters.
The Network Service Name identifies the ISDN/
PSTN Service to the system.
Default name: ISDN/PSTN Service
Note: This field is displayed in all ISDN/PSTN
Network Properties tabs and can contain character
sets that use Unicode encoding.
Select the type of spans (ISDN/PSTN) lines,
supplied by the service provider, that are connected
to the RMX. Each span can be defined as a
separate Network Service, or all the spans from the
same carrier can be defined as part of the same
Network Service.
Select either:
•
T1 (U.S. – 23 B channels + 1 D channel)
•
E1 (Europe – 30 B channels + 1 D channel)
Default: T1
Note: Only one Span Type (E1 or T1) is supported
on the RMX. If you define the first span as type E1
all other spans that you may later define must also
be of type E1.
PRI is the only supported service type. It is
automatically selected.
