Line interface board with 8x E1/T1

  • Lattice ECP3 FPGA providing TSI and TDM-to-iTDM converter
  • Maxim/Dallas DS26518 E1/T1 framer
  • 8x or 16x E1/T1 interfaces towards the front panel
  • 2x GbE towards backplane at base region
  • 2x GbE, 2x SRIO, or 1x PCIe towards backplane at fat-pipe region

Description

Basically, the NAMC-8E1/T1 provides 8 E1/T1 interfaces towards the front panel without further processing resources. If equipped with a mezzanine card, the number of line interfaces of the then so-called NAMC-16E1/T1 board  rises up to 16.

The NAMC-xE1/T1 is designed for (tele-)communication applications with a need for a high aggregation of multiple E1/T1 interfaces combined with access to switched networks based on high bandwidth Ethernet. The TDM-to-I-TDM converter provided by the FPGA connects the on-board E1/T1 interfaces with a Gigabit Ethernet port for system interconnects (I-TDM).
