Overview

Aliathons’s Multi-Channel E1/T1/J1 Framer Core provides a flexible, resource-efficient, high-density programmable logic based solution for PDH interfacing. Running at 155MHz, it is capable of framing and deframing up to 1008/1344 E1/T1 channels (enough for a full OC48/STM16).

Key features

  • Conforms to ITU G.704/ANSI T1.403.
  • Best-in-Class size and performance and supports many hundreds of channels.
  • Generates and performs frame synchronization for the following PDH signals: T1 – (ESF/SF), J1, E1 – (CRC/Non-CRC/ G.706 Interworking)
  • Calculates and inserts CRC; reports CRC values for T1 (ESF), J1 and E1.
  • Frame format of each channel may be configured dynamically and independently.
  • Supports independent timing on every channel while providing frame overhead insertion and extraction interfaces.
  • Provides frame overhead error injection interface and a byte-wide, frame-aligned timeslot input interface. Implements
  • a byte-wide frame aligned payload output interface.
  • Accepts multiple input streams, making it ideal for interfacing to channelized VT/TU Mappers or multi-channel LIUs.
  • Output data streams may dynamically range between 1 and 8 bits wide, allowing seamless interfacing to SONET/SDH VT/TU mappings.
  • Full Overhead and Defect processing per channel including. OOF, AIS, FAS, CRC, E-Bit, RAI, SEF.
  • Performance Monitoring counters (FAS, CRC, E-BIT). Upstream/Downstream Consequent Action.
