The Lucent installation 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 is thoroughly tested and integrated
into a reliable system at cutover. Once approved by Lucent’s Quality Assurance Test
group (the industry’s toughest), the system is turned over to the customer.
The Lucent installation group also provides any specialized engineering and installation

Basic Troubleshooting Techniques
Description
This procedure covers some basic troubleshooting techniques used to isolate and
correct failures during the installation phase. This procedure is directed toward
troubleshooting out-of-service systems only and should not be performed on in-service
equipment.
NOTE:
For troubleshooting in-service equipment, refer to 363-206-290 (Release 5) or
363-206-295 (Release 7), DDM-2000 OC-12 Multiplexer User/Service Manual.
NOTE:
If only green LEDs are lighted, there is no problem with the DDM-2000.
NOTE:
For a description of the LEDs, refer to the “Installation Test” section.
NOTE:
Movement of circuit packs or cables may cause the DDM-2000 to report alarms
due to a configuration mismatch between the SYSCTL and the transmission cir-
cuit packs.
NOTE:
Circuit packs should not be removed or installed unless the SYSCTL is present.
