FAQs

Q: What is Annex B and when is it required?
A: Annex B is ADSL over ISDN. It’s used in regions where ISDN shares the same copper pair; choose Annex B for those deployments.

Q: Does it work on POTS lines?
A: No. For POTS you typically need an Annex A/M variant. This module targets ISDN-based lines.

Q: Is an external splitter necessary?
A: Yes, an ISDN-compliant splitter/filter is typically required when voice/ISDN services share the line.

Q: Can it terminate PPPoE/PPPoA?
A: Yes, PPPoE/PPPoA over ATM are supported subject to IOS feature licensing.
