Troubleshooting is straightforward with the softkey driven menus. The datacom-enhanced BASIC (option 001) programming language can be used for sophisticated analysis or for unique application. BASIC uses many of the menu routines, maintaining softkey ease-of-use, while giving you the capability to write your own programs as needed. The HP 4955A, combined with the HP 18150JA X.25 Conformance Testing and Certification System, provides you with a very powerful tool for certifying equipment for use in X.25 networks. This package contains more than 700 individual test sequences for verifying conformance to the CCITT X.25 specification.
