Section 20 CSR 4240-29.050 - Option to Establish Separate Trunk Groups for LEC-to-LEC Telecommunications Traffic
Current through Register Vol. 49, No. 6, March 15, 2024
PURPOSE: This rule enables terminating carriers to establish trunking arrangements for LEC-to-LEC traffic separate and distinct from trunking arrangements used for IXC traffic.
(1) At its discretion, a terminating carrier may elect to establish separate trunk groups for interexchange carrier (IXC) and Local Exchange Carrier-to-Local Exchange Carrier (LEC-to-LEC) traffic. Terminating tandem carriers shall work cooperatively with, and abide by requests of, terminating carriers to establish separate trunking arrangements for IXC and LEC-to-LEC traffic occurring between a terminating tandem carrier and a terminating end office.
(2) A transiting carrier may opt to not install separate trunk groups to a requesting terminating carrier if the transiting carrier assumes financial responsibility for all compensable transiting traffic delivered to the terminating carrier.
(3) All terminating carriers electing to create category 11-01-XX records shall establish a trunk group for LEC-to-LEC traffic that is separate from trunk groups for IXC traffic. Such LEC-to-LEC trunk group shall be used to connect the end office to the tandem serving that end office.
(4) After a terminating carrier elects to establish separate trunk groups for IXC and LEC-to-LEC traffic, IXC traffic shall not be placed on the LEC-to-LEC trunks between the terminating tandem carrier and terminating end office.
