ISDN Connection Management

Address Connect

An Address Connect connection is an ISDN connection that is established to a specific destination P840 dependent upon the destination network address contained within traffic received from the local LAN.

When a device on the local LAN wishes to establish a session with a device on a remote LAN, the local device will send a frame with a destination address of the remote device. The P840 will receive the frame and examine the destination network address contained within the frame.

If the P840 can determine the route to the destination network address, the frame is passed along to one of the currently connected partner P840 Routers. If the destination network is not located on a currently connected partner P840, the local P840 will then look in the Address Connect table to determine which partner P840 to call.

The Address Connect tables are used by the P840 to determine which remote P840 is called when a specific destination network address is requested from a device on the local LAN. The Address Connect tables are configured by the P840 operator.
