Description

Soem initial tests with a PrTel93i doing BERT testing on a single B-channel indicates we have some problems to investigate.

This ticket serves as log of the various tests/attempts so far

  • PrTel93i against same PrTel93i doing internal call through Auerswald COMmander2 PBX
    • 0 errors in several 1min and 15min calls. So the PrTel and the wiring are good.
  • PrTel93i against same PrTel93i doing external call through same PBX but going out via icE1usb to OCTOI hub and calling back through the same path:
    • first 1min call was with 0 errors
    • first 15min call was with 6.62 E-2 BER
    • second 15min call was with 5.92 E-2 BER
    • no lost / reordered OCTOI frames observed during that time
  • PrTel93i against bchan_loop from capi-hacks (hfc-usb, mISDN, CAPI20) doing internal call through Auerswald COMmander2 PBX
    • 1min call with 4.25 E-1 BER
    • so clearly there are some problems in the misdn/capi integration
