Comprehensive testing          The wire-testing service is
of all media types             applicable to all media types (coaxial,
                               unshielded and shielded twisted- pair,
                               and fiber-optic). HP uses specific and
                               sophisticated test equipment for each
                               media type to verify that the wiring
                               complies with specifications.

                               HP performs a complete audit of the
                               existing cabling topology to ensure that
                               all network-related components are
                               correctly located and the distances
                               between drops are within specifications.
                               Any discrepancies are documented and
                               recommendations for correction are
                               provided. HP electronically certifies
                               that all transmission components adhere
                               to predefined specifications.

Evaluation of existing          As applicable, the certification
coaxial and fiber-optic cables  specifically includes the following:

                               o All coaxial cable runs are
                                 tested with a Time Domain
                                 Reflectometer to ensure that every
                                 cable segment is properly terminated
                                 and of correct, uniform impedance. 
                                 Fiber-optic cables are tested with an
                                 Optic Time Domain Reflectometer.

                               o Transceivers, media access units, and
                                 fiber-optic link sets are visually
                                 inspected for proper termination and
                                 integrity.

                               o Proper grounding and signal shielding
                                 is verified.

Evaluation of existing        Twisted-pair cable allows for variations
twisted-pair wiring for       in physical characteristics and has
use with 10BaseT networks     dynamic performance requirements.  HP's
                              wire-test instrument verifies and
                              troubleshoots twisted-pair cabling to
                              evaluate the key parameters specified by
                              the IEEE 802.3 to 10BaseT standard:
                              crosstalk attenuation, signal attenuation
                              over frequency, burst noise, and
                              continuity. Specially trained HP engineers
                              perform testing and evaluation of the
                              results.  This service provides you with
                              the assurance that the existing wiring
                              complies with specifications for 10BaseT
                              data transmission.


Complete test documentation and    HP documents certification test
