Dedicated Transport Dark Fiber. At 251(c)(3) Unbundled dedicated transport dark fiber segments in routes that have not been Declassified, AT&T will provide a UNE Dedicated Transport Dark Fiber segment that is considered “spare” as defined in Section 12.6 and 12.7 below. UNE Dedicated Transport Dark Fiber is defined as AT&T dark fiber interoffice transmission facilities dedicated to a particular CLEC that are within AT&T’s network, connecting AT&T switches or wire centers within a LATA. UNE Dedicated Transport Dark Fiber does not include transmission facilities between the AT&T network and the CLEC network or the location of CLEC equipment. AT&T will offer dedicated transport dark fiber to CLEC when CLEC has collocation space in each AT&T CO where the requested dedicated transport dark fiber(s) terminate.
