ADSL Modules for the ProCurve Secure
Router
ProCurve Networking offers two ADSL modules:
■ ADSL2+ Annex A module for ADSL over POTS
■ ADSL2+ Annex B module for ADSL over ISDN
ADSL2+ Annex A modules are used primarily in the United States and Canada.
ADSL2+ Annex B modules are used in Europe, South America, Asia (except
Japan), and Australia.
Note Japan uses ADSL Annex C. Currently, the ProCurve Secure Router does not
support ADSL Annex C.
The ProCurve ADSL2+ Annex A and Annex B modules support standards for
ADSL, ATM, Point-to-Point Protocol over Ethernet (PPPoE), and PPP over
ATM (PPPoA). (See Table 7-2.)
