If the product uses various components that are interconnected together, document will be
applicable for interconnection between the various external components and cabling in addition
to stand-alone Common Systems components that may have been standardized with other
products within the ATT Local Exchange companies. If the OEM has presented a solution that
uses “off the shelf” separate components that are externally cabled within the bay or relay rack,
validation and use of the ATT standard product lines shall be given.
Example: All DSX-1, DSX-3 and FDF panels will be provided by ADC Telecommunications
Inc. for the ATT Local Exchange companies.
Finally, determinations will need to be made with AT&T Local Exchange company’s technical
staff as to whether the items provided within the product meet either pre-assembled
requirements or will be field assembled. Pre-assembled products will be considered within
any
Network Equipment/Element hardware box or panel that includes intelligent hardware or
software. The assembly of multiple pre-assembled Network Equipment/Element products
within the same footprint will be negotiated with the AT&T Local Exchange companies. The
assembly of multiple pre-assembled Network Equipment/Element products outside of the same
footprint will be handled as a field assembled installation. Any Network Equipment/Element
that uses a passive product panel or box that does not include intelligent hardware or software
will meet ATT Local Exchange Company’s and AT&T Corporation’s product approval standards
and will be field assembled.
All assemblies, including internal wiring between components shall meet workmanship
standards that include a neat and well-secured assembly with no sharp edges or cable/wire
ends exposed.
