A system is shown for interfacing between a work station or intelligent terminal device and a number of maintainable telecommunication systems. This system provides for interfacing between an intelligent CRT terminal and up to 26 remotely located maintenance processor units. This system provides the CRT attendant or crafts person with the ability to trouble-shoot or perform diagnostic testing upon a maintenance processor unit which is remotely located. In addition, the work station or intelligent terminal may be remotely located from the interface circuitry. This system establishes a connection between the work station or intelligent terminal and a particular maintenance processor unit. Once that connection is established, the maintenance processor unit of that telecommunications system reports diagnostic and trouble-shooting type information. This system also provides for manual reset and self test capabilities. This system provides for a variable BAUD rate which may be preprogrammed into a microcontroller device.
