ISDN service
ISDN Call Identification Display is provided in addition to the normal Telephone Display and Attendant

call is handled (for example, whether it is redirected or not), and the information is available on the call.
CPN/BN to Host Call Identification
The CPN/BN to Host Call Identification enables CPN and BN information to be passed from
Communication Manager to the ISDN Gateway, so that the ISDN Gateway can forward the information
to a host for data-screen delivery to agents in an ACD split.
By delivering call-identification information such as CPN/BN and additional Communication Manager
information such as the answering-agent's extension to an adjunct network (ISDN Gateway), the adjunct
automatically delivers data screens to agents for new calls and call transfers.
The figure below shows a simplified diagram of a CPN- and BN-to-host arrangement. The ISDN
Gateway is a UNIX or MS-DOS® computer connected to Communication Manager on one side and to a
host computer on the other side. The media server connection is over a synchronous interface with BX.25
protocol.
