ATIS currently oversees eight committees including those described below. Committee T1 was established in 1983 and is accredited by the American National Standards Institute. Two committees that have addressed ONA issues are the T1M1 and T1E1 Committees. Requests for ONA services are accepted as Issues . Issues remain active until consensus is reached or a lack of overall interest in the issue is demonstrated.
Resolved issues become voluntary recommendations that IILC participants generally adhere to.
It is possible for each carrier to tailor an IILC recommendation. The IILC is the primary forum used to resolve ONA issues. The IILC has touched upon a few security related ONA issues. Any member of the IILC is allowed to propose new issues for requested services. Specific requests for enhanced services are evaluated based on expected market demand, their utility as perceived by ESPs, and the technical and cost feasibility of unbundling and providing those services.
