This handbook describes messages associated with Version 3 of the Communications Control INTERCOM (CCI 3.0) that is used with the CONTROL DATA 2550 Series Network Processing Unit (NPU). The CCI is the operating software for the NPU which provides front-end and remote message distribution functions for a CDC 6000 or CYBER 70/170 host computer system. The CYBER host system operates under control of the NOS/BE operating system.
Two types of diagnostics are described; the inline diagnostic that is an integral part of the CCI, and the optional on-line diagnostics for testing network lines. Off-line diagnostics are discussed in the appropriate hardware reference manuals.
The purpose of these descriptions is to assist system operators and customer engineers (CEs) in the isolation of system faults. Any codes appearing within these messages are described and defined. Brief instructions on dump interpretation are also provided. To interpret the dump, either with or without a halt code, the user will need a link edit listing of the CCI for this NPU.
