Abstract

This article relates to a procedure which allows a customer to intall a remote communication controller comprising a base unit and an expansion unit which have been manufactured separately. It does not require a keyboard/display console. Presently, communication controllers exist which comprise a base unit which may be connected to a limited number of communication lines and an expansion unit which allows the number of communication lines to be increased. The communication controllers may be of two types: the local type which attaches to a host channel and the remote type which connects upstream to another controller through a communication line. The remote type is designed to be installed in an office environment by the customer himself.

Customer Set-Up Procedure for a Communication Controller

This article relates to a procedure which allows a customer to intall a remote communication controller comprising a base unit and an expansion unit which have been manufactured separately. It does not require a keyboard/display console. Presently, communication controllers exist which comprise a base unit which may be connected to a limited number of communication lines and an expansion unit which allows the number of communication lines to be increased. The communication controllers may be of two types: the local type which attaches to a host channel and the remote type which connects upstream to another controller through a communication line. The remote type is designed to be installed in an office environment by the customer himself. The customer set- up functions involve two parts: a specific manufacturing process and the installation itself. During the manufacturing process, the base unit is configured according to the customer order, i.e., the type and number of line adapters. Using an attached local console, the manufacturing personnel invoke a service processor microcode utility which senses the presence of each component in the base and creates a configuration data file (CDF) disk. The console allows this file to be displayed and to check if all configured line adapters have been recognized. The base unit is then tested at manufacturing according to the configuration recorded in the CDF disk and shipped with the CDF present on the disk. Primary and secondary diskettes are shipped with the microcode. The expansion unit, if any, is also configured with line adapters according to the customer order, and it is connected for test purposes to a manufacturing base unit which is used for all manufactured expansion units. Then, the service processor microcode utility senses and creates the CDF of the manufacturing base unit and of the interconnect expansion unit on the disk of the manufacturing base unit. The specific ordered expansion unit is tested interconnected to the manufacturing base unit according to the complete (base plus expansion) recorded CDF. When the test is completed, a service processor utility allows the CDF to be saved from the disk of the manufacturing base unit to a specific expansion diskette. At the customer site, when the base unit or the base unit plus the expansion unit are unpacked, put in place and interconnected, if base and expansion units are received, the following steps are performed by the customer. In order to test the machine connectors of the service processor console ports, the customer installs a wrap plug for each of the console ports of the communication controller: local console port, remote console port and so on. The customer connects the line cables to the various line adapters. The customer attaches the power cable. The customer installs the primary diskette which comes with the base unit in the diskette drive and locks it. He...
