7 VDSL2, MELT, Vectoring

8 The Broadband Service Mix Possible issues affecting the copper lines Intermittent contact Powered-down CPE Powered-up CPE, but no sync Missing POTS splitter Untwisted in-house wiring Crosstalk (possibly Impulse noise time-varying) Equipment fault Open circuit MDF Short circuit miswiring Loop unbalance RFI (possibly time-varying) Degraded contact CPE interop problem

9 Evolution from external test heads to integrated DSLAM testing Operator Operator Test head Network Analyser control for processing Test head Test Access Matrix Access network Access network DSLAM DSLAM Integrated measurement on line card External Testhead solution Integrated testing and 5530 NA-C Test access matrix internal to ISAM: MTA solution Test access matrix external to ISAM: ADF solution or external TAM Bundled NA+ISAM solution SELT + DELT Can be complemented by NBLT / MELT
