Introduction

These release notes describe new enhancements and fixed caveats for the VDSL CPE PHY using firmware release B2pvC038u. This firmware is used for Cisco CPEs and certified by Deutsch Telekom with its Digital Subscriber Line Access Multiplexers (DSLAMs). Cisco does not support any CPE interoperability issues if the CPEs are not tested with the DSLAMs by Deutsch Telekom. In this firmware Annex J mode is enabled.

These release notes are updated as needed.
