Dummy

Intro

  • Gateway software to run on on-site E1 connection (see artice E1/T1 Interface)
  • Transmits application-level messages between CTS E1 and TetraPack Core
  • Decodes/encodes full signalling stack:
    • E1 handler  \
    • HDLC FSM  - (normally done by IC on BSC411 board)
    • Q.921 FSM  /
  • Inter-site Connect transport including priority management (normally done by ISCD2.EXE)
  • Decodes/encodes E1 and pre-buffer carrier streams (normally done by BSC411/TR412 boards)
  • Partially emulates BSS.EXE/GWS.EXE (presence / status updates)
  • VTUN over E1 between CTS and host (does not forward to the server)
  • Uses the same bss3.txt configuration file as a base-station
  • Debian 11 arm64 or amd64, tested on Raspberry Pi 3*, CM4 and Intel x64 PC
  • Typical IP bandwith 4-100 Kbits/sec

* Some revisions of Raspberry Pi 3 have issues with icE1usb connection stability due to USB NIC
