Description

I've been hacking up a DAHDI driver for the icE1usb, which is currently available [only] from https://github.com/osmocom/dahdi-linux/tree/laforge/icE1usb

The current code seems to be working fine
  • it survives manual USB unplug/replug tests
  • it survives hundreds of rmmod/insmod cycles
  • it causes no CRC errors when used with e1-prbs-test over multiple hours
It has a number of missing features:
  • no reporting of errors via DAHDI APIs (alarms, crc erorrs, ...)
  • no reporting of link status via DAHDI APIs (RED/YELLOW/BLUE/...)
  • no control over local/remote clock usage

Checklist

  • host repository on osmocom.org
  • RED alarm on LOS
  • YELLOW alarm
  • BLUE alarm
  • error counters/stats via DAHDI APIs
  • CRC4 enable/disable
  • select local/remote clock source via DAHDI
