Abstract:

A method for connecting an externally accessible shared serial port to one of a plurality of target serial ports is provided. The target serial ports are associated with a plurality of different application cards within a shelf assembly. The method includes receiving, from an external device connected to an externally accessible shared serial port, a request for a connection between the externally accessible shared serial port and one of a plurality of target serial ports within a shelf assembly associated with a plurality of different application cards, and determining whether shelf resources are available to connect the externally accessible shared serial port to the requested target serial port. In response to determining that shelf resources are available, the externally accessible shared serial port is connected to the requested target serial port.

Abstract:

The data line card printed board assembly provides an interface between a switching system and data terminal equipment operating in a selected one of a synchronous mode, an asynchronous mode and a synchronous polled mode and at a selected one of a plurality of different data rates. This assembly comprises a first arrangement coupled to the switching system to provide a first bidirectional communication path between the switching system and the data line card and a second arrangement coupled to the first arrangement and the data terminal equipment to provide the first bidirectional communication path between the first of the data terminal equipment and the data line card card. A computer arrangement diposed on the printed board assembly is coupled to the first and second arrangement for bidirectional control thereof to accommodate the selected one of the modes and the selected one of the plurality of different data rates. The assembly further includes a third arrangement coupled to the switching system and the computer arrangement to provide a second bidirectional communication path between the switching system and the data line card with the third arrangement being controlled by the computer arrangement.
