ISDN is an emerging technology on the leading edge of international digital communication's net-
working. Always check with your NEC America Technical Service Representative before setting up your
ISDN application. Working together will ensure maximum compatibility and reliable ISDN performance.
SMDR Includes Dialed Number
The SMDR report can optionally print the trunk's name (entered in system programming) or the number
the incoming caller dialed (i.e., the dialed ISDN digits). This gives you the option of analyzing the SMDR
report based on the number your callers dial. (This option also applies to a DID trunk as well.)
Display Shows Why Caller ID is Not Available
With Caller ID enabled, the system will provide information for ISDN calls that do not contain the Caller
ID information. If the Caller ID information is restricted, the telephone display will show "PRIVATE". If
the system is not able to provide Caller ID information because the telco information is not available, then
the display will show "OUT OF AREA".
Calling Party Number Notification
The system can provide calling party number notification for outgoing ISDN calls. When a call is made on
an ISDN line by an extension, the system will send the identification for the extension placing the call, if it's
programmed. If there is no Extension Calling Number assigned, the system will send the calling number
for the ISDN trunk. If both the extension and trunk information is programmed, the extension information
will be sent as it takes priority.
When the option for calling party subaddress is on, the extension number will be sent as the subaddress
information. Both the calling party number and calling party subaddress are sent in a SETUP message as
the calling party information element and a calling party subaddress information element.
Primary Rate Interface (PRI)
The system is compatible with ISDN Primary Rate Interface (PRI) services. PRI services currently
supported include:
Basic PRI Call Control (BCC)
Display of incoming caller's name and number when allowed by telco
Routing in the system based on the number the caller dialed
ISDN maintenance functions (such as In Service/Out of Service Messaging)
Speech and 3.1 KHz audio
PRI capability requires the installation of T1/PRI Interface PCBs (0891009). The T1/PRI Interface PCB
uses a single slot.
