Sec. 61.134  Concurrences for through services.

    A carrier filing rates or regulations for through services between 
points on its own system and points on another carrier's system (or 
systems), or between points on another carrier's system (or systems), 
must list all concurring, connecting or other participating carriers as 
provided in Sec. 61.54 (f), (g) and (h). A concurring carrier must 
tender a properly executed instrument of concurrence to the issuing 
carrier. If rates and regulations of the other carriers engaging in the 
through service(s) are not specified in the issuing carrier's tariff, 
that tariff must state where the other carrier's rates and regulations 
can be found. Such reference(s) must contain the FCC number(s) of the 
referenced tariff publication(s), the exact name(s) of the carrier(s) 
issuing such tariff publication(s), and must clearly state how the rates 
and regulations in the separate publications apply.
