ISDN PRI FEATURES
Iwatsu Enterprise-CS supports the following features on ISDN PRI Lines:
Call-by-Call Service Selection
The Call-by-Call Service Selection feature is an additional service provided
over ISDN PRI Lines that enables a single span to handle different types of
Network Specific Features (NSF) without requiring dedicated channels for
each NSF. Iwatsu Enterprise-CS Software supports four Call-by-Call NSF
services:
In-WATS
Out-WATS
FX (Foreign Exchange)
E&M Tie Trunk
ISDN Calling Number Identification Service (I-CNIS)
Iwatsu Enterprise-CS supports the ISDN Calling Number Identification
Service (I-CNIS) feature on ISDN PRI lines. This feature is available from
many ISDN PRI service providers. The I-CNIS number is sent with a call
over an ISDN PRI line. It identifies from where the call originated.
The I-CNIS number provided with an outgoing call on an ISDN PRI line
may be generated in one of three ways (Listed in order of priority):
1. At the station level using station speed dial bin 97. The number
programmed in Personal Speed Dial Bin 97 is sent as the I-CNIS with
the call.
2. At the ISDN Trunk Group level. The I-CNIS number programmed in
the Iwatsu Enterprise-CS database for the ISDN Trunk Group is sent
with the call.
3. Using the Central Office provided Directory Number. The ISDN
Service Provider assigns this number.
Fractional DS1
This feature allows individual B-channels on the span to be programmed as
active or inactive. A separate agreement with the ISDN service provider is
necessary for performing fractional DS1. This service may not be available
in all areas.
