Further unbundling remains a long-term objective of ONA. The FCC's Phase I Order required unbundling ``to the extent technologically feasible''[para. 216]phase1. The IILC was directed, in the BOC ONA Order, to address the potential technical and operational problems posed by more extensive unbundling of the network [pages 41-43]onaorder. The BOC ONA Amendment Order required each carrier to amend its plan to describe any change to its plans for developing and implementing new technologies such as SS7, ISDN, and IN technologies, including a description of (1) how it will unbundle the services provided through the use of such technologies and generally how those services will fit into the ONA framework; (2) ONA services that these technologies could support; and (3) its plans for offering such services [24]. With further unbundling of the network, many security concerns will arise.
IILC Issue 026 is titled Long Term Unbundling and Network Evolution. ``This issue addresses the FCC directive to examine, through the IILC, the technical, operational and administrative issues associated with further unbundling and modular architecture. Since the February IILC meeting the task group has finalized and validated the identified physical points of interconnection, has developed a matrix of logical interconnection options, and is currently seeking validation of these logical interpretations''[28] This issue considered Issue 022 unbundling criteria, has resulted in several Unbundling Forums, and has been a topic of discussion since 1991. It is important that security concerns be taken into account for planning further unbundling of the network.
