Conformance Test SuitesConformance Test SuitesConformance Test SuitesConformance Test Suites

• ITU-T G.994.1 (G.hs) Conformance– Transmission and modulation– Start-up/clear-down– Framing and messages

• CPE Network Access Protocol Conformance– AAL5 – PPP (LCP, authentication, IPCP)– Encapsulation of PPP (PPPoA, PPPoE)

• ITU-T G.992.3 Annex A/B Electrical Characteristics Conformance– Physical layer measurements (balance, LOV, etc.)– Spectral compatibility

Interoperability Test SuitesInteroperability Test SuitesInteroperability Test SuitesInteroperability Test Suites

• Basic interoperability – Does it work?

• Connection stable? Internet access?– DUT vs. multiple devices

• Reach vs. Rate (for ADSL, ADSL2, ADSL2+)– Detailed interoperability testing in a variety of simulated loop and

crosstalk environments (worst-case scenario)– DUT vs. one device

• ITU-T G.996.1 (G.test) for Region A– Similar to Reach vs. Rate; incorporates BERT (Reach vs. Rate does

not)• DSL Forum TR-048/067

– For pre-certification purposes only– The UNH-IOL has chosen not to become a DSL Forum Independent
