· Adaptive frequency-domain equalization for better robustness in environment with bridgedtaps.
· Applicable to both ends of loop: LT and NT.
· Protection against 250ms duration impulsive noises thanks to Programmable Reed-Solomon Codec RS (N, K) and configurable triangular interleaver.
· Implements Discrete Multitone (DMT) modulation and Digital Frequency Division Duplexing (FDD) for deployment flexibility.
· Embedded Operation Channel messages (EOC) for continuous and on-line monitoring on the communication link between LT and NT.
· Support all frequency band plans (998, 997 and Fx) specified in ETSI, ANSI and ITU-T standard draft documents.
· Fast and/or slow data-path selectable at startup.
· Selection of frequency band plan by software under Network Management (NM) control.
· ATM Transmission Convergence layer (ATMTC) with Utopia interface (level 2).
· Support analogue bandwidth up to 12 MHz with an embedded 4096-tone IFFT/FFT processor.
· 64kps user rate granularity.
· Embedded modem control Software for line parameters set-up, communication link initialization, show time monitoring and telemetry information collection (BER, SNR,standard deviation).
· Generation of deep frequency notches under NM control.
· Mapping/demapping functions supporting constellation size up to 16384 points (14 bits).
· Protection against two simultaneous; RF HAM ingress
· Adaptive bit-loading algorithm for maximal use of the channel capacity.
· Accurate PSD monitoring and adaptation to comply to reference PSD masks specified in ETSI and ANSI standard draft documents.
· Control and Maintenance via a Operation and Maintenance API from an external controller true the embedded CTRL-E interface.
