ASC EC Guidelines for Meet Point Switched & Special Access Orders

This guideline, effective June 1st, 2014, clarifies which LEC (Local Exchange Carrier) will assume the roles of ASC EC (Access Service Coordination Exchange Carrier) and OEC (Other Exchange Carrier) for Switched and Special Access services ordered on a Meet Point basis. AT&T, CenturyLink, Frontier, Verizon and Windstream are implementing the guidelines set forth on the following pages.

IMPORTANT NOTES:

 The ASC-EC/OEC determination guidelines listed in the table below only apply to participating Local Exchange Carriers (LECs), as identified by State, OCN and ICSC.

 Where cells in the table below indicate “N/A”, the LEC does not offer Meet Point services with other LECs listed in the table.

 Where cells in the table indicate “Always ASC_EC”, that LEC will always be ASC_EC and other LECs listed will always be OEC for Meet Point services involving the “Always ASC_EC” LEC. For example, in the state of NY:

o For Meet Point services between Frontier and Windstream, these guidelines will be followed to determine whether Frontier or Windstream will be ASC_EC or OEC for any given order. o For Meet Point services between Frontier and Verizon, Verizon will always be ASC_EC and Frontier will always be OEC for all orders. o For Meet Point services between Windstream and Verizon, Verizon will always be ASC_EC and Windstream will always be OEC for all orders.

 The guidelines listed below only apply to orders for new Meet Point circuits and not to the disconnection/rearrangement/replacement of existing Meet Point circuits.

 For the disconnection/rearrangement/replacement of existing Meet Point circuits (example: CFA rolls), the ASC_EC/OEC relationship will remain the same as it was for the existing circuit when it was initially ordered.

MEET POINT SWITCHED ACCESS:

ASC EC Guidelines for Meet Point Orders Page 1 ASC EC Guidelines for Meet Point Switched & Special Access Orders

 ASC_EC = First Point of Switching (SECLOC), except for:

o “Always ASC_EC” exceptions listed in the table below.

MEET POINT SPECIAL ACCESS:

 ASC_EC = SECLOC, except for:

o Multipoint, the ASC_EC will be the First Point of Bridging (ACTL). o Ethernet, the ASC_EC is not determined by these guidelines. Check with the individual LECs involved. o OCn, the ASC_EC is not determined by these guidelines. Check with individual LECs involved. o “Always ASC_EC” exceptions listed in the table below.
