Case 09-07-021 (Filed July 20, 2009)

DECISION MODIFYING REHEARING DECISION (D.) 11-07-032
AND UNDERLYING D.10-07-005

1. Summary

In this Decision, we dispose of the petitions for modification of Decision (D.) 11-07-032 filed by Pacific Bell Telephone Company d/b/a AT&T California (AT&T) and XO Communications Services, Inc. (XO) on August 16, 2011 and August 25, 2011, respectively. We modify D.11-07-032 (and the underlying decision, D.10-07-005) by ruling that the interconnection agreement (ICA) between XO and AT&T provides XO with the right to cross-connects between XO's and other competitive local exchange carriers' collocated equipment via AT&T's main distribution frame (MDF), and that the applicable rate for such cross-connects via the MDF is the federal Total Element Long Run Incremental Cost rate set forth in the parties' ICA.
