AIC INSTALLATION STANDARDS (AICIS)
Introduction
This document presents detailed requirements covering all AIC infrastructure installations.
Requirements are divided into Sections with each sections focused on a key area(s) needed to
realize a quality installation. The expectation is that the vendors will understand these requirements
and apply them to all AIC installation they deliver. These requirements cover all technical spaces AIC
is deployed in which includes CO, SNRCs, IDC, EDC and NTC. As new technical spaces are
introduced an effort will be made to examine and extend application of AICIS to this new space. Any
reference to standard or industry standards should be interpreted as a reference to TIAA standards.
Presented first are the general overall guideline used to craft these detailed requirements.
Overall Guidelines
AIC standards should only include installation requirements that are Critical to Safety and
Critical to Service. Any other requirements become best practices/guidance for the installation
vendors and will not be enforced
This guideline involves inclusion of only those installation requirements, in AIC Installation standards,
that ensure:
1. Safety of AT&T/Vendor employees and
2. Avoiding conditions, caused by poor workmanship, that are highly likely to cause a service
outage within useful life of the platform (3-5 years).
