FAQs

Q: Which services does Annex A support?
A: Annex A operates over POTS lines; use with appropriate POTS splitters/filters when sharing with analog voice.

Q: Will it fall back to ADSL2+ if VDSL2 is unavailable?
A: Yes. It supports VDSL2 with fallback to ADSL2/ADSL2+ depending on line provisioning.

Q: What speeds can I expect?
A: Speeds depend on VDSL2 profile, line quality, and loop length. Short loops can achieve significantly higher rates than long loops.

Q: Is PPPoE supported?
A: Yes. PPPoE and typical DSL encapsulations are supported via PTM (VDSL2) and ATM (ADSL).
