Does the FEP require licensed code?
Yes, the FEP requires licensed code on several levels. First, the Service Processor (SP4) and 3746-900 require licensed code which is provided on every FEP installed by Mid-Atlantic Research. To ensure a high level of serviceability and reliability we provide the highest level code authorized by IBM for distribution. Second, the FEP operates under the control of a licensed program (program 5648-063) commonly known as NCP (Network Control Program). NCP is licensed and distributed directly by IBM to the end user.
