Agree on that, bitswap is needed. Speaking about modem tweaking, @Bully could try to cap his line, the only issue maybe that he won’t be able to remove cap, even on fastpath because as soon he remove it he will be banded again. And with higher snr he should be able to achieve better line stability, unless he will be able to get engineer to check his line.
Higher SNR is good for stability, alas @Bully has always had issues with synch rates and 39Mb currently is a great improvement,
@UkSentinel Yesterday exercise wasn’t good idea, I had two bursts of CRC errors (one over 6k and one over 11k errors) today my line is interleaved on downstream (thanks God only on downstream). So looks like for me vigor is doing a very good job with FEC on downstream 😉. I swapped modems yesterday evening but obviously was too late, scored CRCs during the day judged on DLM decision.
Vigor (Lantiq) are quality chipsets usually at the cost of slightly lower synch. I wonder what caused your CRC bursts ?
I wonder if : (from a stability/reliability perspective)
- Lantiq Modem chipsets work well on Broadcom exchanges/cabs
- Lantiq Modem chipsets work well on IFTN (ECI) exchanges/cabs
- Broadcom Modem chipsets work well on Broadcom exchanges/cabs
- Broadcom Modem chipsets work poorly on IFTN (ECI) exchanges/cabs
(how long is that piece of string)
