Type of Change:
Bell Atlantic disclosed in November 1998 network specifications in connection with the provision of high speed packetized data transport ofinformation between Data Information Users and Data Information Providers using DMT technology. This notice is to provide additional information.
ADSL Data Network Release 1 requires either IP over Ethernet over ATM or PPPoE over ATM to be transmitted into the ADN from the customer premises equipment.
ADSL Data Network Release 2 requires either PPPoE over ATM or PPP over AAL5 to be transmitted into the ADN from the customer premises equipment. ADSL Release 2 is a public data service supporting unrestricted communication between Data Information Users and Data Information Providers.
Reference Documents- Internet Engineering Task Force (IETF) Request for Comments (RFC): RFC 2516 † A Method for Transmitting PPP over Ethernet (PPPoE) RFC 1483 † Multiprotocol Encapsulation over ATM Adaptation Layer 5- Encapsulation for Bridged Protocols (section 4.2) RFC 2364 † PPP over AAL5

Dates changes are to occur:
ADN Release 1 is available now. ADN Release 2 is planned for limited deployment in the 3rd quarter of 1999, and more general deployment in the 4th quarter of 1999.
Reasonably foreseeable impact of change:
Compatible CPE will be required. Release 1 will be phased out after the introduction of Release 2 at a particular site.
