You may change this name at startup time using the command line option '--conf <<u>confFileName</u>>'. This allows running several BNC jobs in parallel on the same host using different sets of configuration options. <u>confFileName</u> stands either for the full path to a configuration file or just for a file name.

Service providers and vendors have asked for a standard that would be more efficient, easy to use, and more easily adaptable to new situations. The main complaint was that the Version 2 parity scheme was wasteful of bandwidth. Another complaint was that the parity is not independent from word to word. Still another was that even with so many bits devoted to parity, the actual integrity of the message was not as high as it should be. Plus, 30-bit words are awkward to handle. The Version 3 standard is intended to correct these weaknesses. … … 2640 2642 </p> 2641 2643 2642 <p><a name="config"><h4> 6.3. Configuration Example</h4></p>2644 <p><a name="config"><h4>7.3.
