Configure DSL Signaling Protocol
Note If you are integrating your Cisco router into a European network, please use one of the following
commands:
For CO mode, use the dsl dsl-mode shdsl symmetric annex {A | B | B-ANFP} command to choose
annex B or B-ANFP.
For CPE mode, use the dsl dsl-mode shdsl symmetric annex {A | A-B | A-B-ANFP | B | B-ANFP} to
choose any option except option A.
The router uses annex A by default (United States).
