The following examples are typical AC applications:

• A local data endpoint that connects to a local or a remote access endpoint, such as:

  • A modular processor data model (MPDM) ACCUNET digital service that connects to SDDN over an ISDN trunk-group DS1 port; an MPDM

  • An MPDM ACCUNET digital service that connects to an ACCUNET Switched 56 Service over a DS1 port

• A local-access endpoint that connects to a local or a remote access endpoint, such as a DSO cross-connect and a 4-wire leased-line modem to a 4-wire modem connection over an analog tie trunk

• A local data endpoint that connects to a local or a remote data endpoint such as a connection between two 3270 data modules
