Collocation - CLEC-to-CLEC Connections Overview - V5.0

History Log


Competitive Local Exchange Carrier (CLEC)-to-CLEC Connections allow CLECs to connect with each other within a CenturyLink™ premises for the purpose of mutually exchanging traffic.

CLEC-to-CLEC Connections may be used to connect Collocation spaces of two different parties within the same CenturyLink premises and may also be used to connect multiple forms of a CLEC's Collocations within the same CenturyLink premises (e.g., Physical to Physical, Physical to Virtual, Virtual to Virtual, or non-contiguous cageless bays).

There are two forms of CLEC-to-CLEC Connections:

  • Direct CLEC-to-CLEC Connection is a path engineered by CenturyLink between two Collocation spaces, however the CLEC(s) will be responsible for placing and connecting the cable.
  • CLEC-to-CLEC Cross-Connect is a cross connection, between two Collocation spaces, made on an Interconnection Distribution Frame (ICDF) utilizing the terminations of the two Collocation spaces. The CLEC-to-CLEC Cross-Connect is typically engineered and connected by CenturyLink. CLEC may choose to install the Cross-Connect themselves, or request that CenturyLink install the cross connect if the Collocations terminations reside on the same ICDF. If the Collocation terminations being connected are on different ICDFs, then CenturyLink must perform the cross connect.  CenturyLink will also engineer regeneration into the Cross Connect if it is needed to meet standards.  

Additional information regarding CLEC-to-CLEC Connections can be found in your Interconnection Agreement.
