ISDN PRI
Integrated Services Digital Network (ISDN) technology provides a fast, accurate
and reliable means of sending and receiving data, image text and voice information
through the telephone system.
Using ISDN Primary Rate Interface (PRI) allows for faster transmission speeds and
the addition of a variety of powerful business applications, including remote LAN
access, videoconferencing, file transfer, and Internet access.
Your installer configures your ISDN services and terminal equipment.
Benefits
PRI is economical because separate analog trunks and data circuits are not needed
for Direct Inward Dialing (DID), Direct Outward Dialing (DOD) and data transfer.
With PRI there is greater flexibility because B channels can be dynamically
reconfigured to accommodate changes in traffic with the Call by Call feature. For
more information see Call by Call service selection for PRI on page 113.
PRI offers fast information access because channel usage is optimized to allow you
the full benefit of available bandwidth and real-time connectivity.
PRI lines are configured as DID lines. Incoming calls on a PRI line can appear on
a DID button or on an intercom button depending on how your Enterprise Edge set
has been configured. Outgoing calls are made from the intercom buttons.
PRI lines can be accessed from all devices such as Enterprise Edge sets and wireless
sets.
ISDN PRI features
Selected ISDN network features can be used from an Enterprise Edge telephone.
Your central office switch (ISDN network) determines which features are available
to you.
Network Name Display for PRI
Your Enterprise Edge system displays the name of an incoming call when it is
available from the service provider. Name information can be displayed on an
Enterprise Edge set. If the Calling Party Name has the status of “private” it may be
displayed as “Private name”. If the Calling Party Name is unavailable it may be
displayed as “Unknown name”.
Your Enterprise Edge system displays the name of the called party on an outgoing
call, when it is provided by your service provider.
