Troubleshooting
The Engineering and Installation Services group provides the customer with an
individually tailored, quality-tested job that meets our published high standards
and the customer’s operational requirements. The group ensures that the
customer’s system order is integrated into a complete working system tailored to
office conditions and preferences. This process provides for the customer’s
complete needs. It includes provisions for cabling, lighting, power equipment, and
ancillary connections to local and/or remote alarm systems. The group will also
respond to any customer changes that occur during installation.
All equipment engineered and installed by Lucent Technologies is thoroughly
tested and integrated into a reliable system at cutover. Once approved by Lucent
Technologies’ Quality Assurance Test group, the system is turned over to the
customer.
The group also provides any specialized engineering and installation services
required for unusual or highly individualized applications. These specialized
services may include engineering consultations and data base preparation. Your
local Account Executive can provide more information about these services.
