NM-HSSI <-> kentrox <-> kentrox <-> NM-HSSI works just fine. The problem
is not on the link level with AIS or clocking, that works just fine.
NM-HSSI <-> kentrox <-> PCI DS3 card
that doesnt work. There is no telco in between, only two RG59 coax cables.
As has been stated, this is most likely a DSU framing issue. So my
Does anyone know what the difference is between a Cisco DS3
interface in "cisco framing mode" and a kentrox in "kentrox framing mode",
and if it's likely that this would be handled by the driver on the Linux
side of the DS3 card, or if this is a microcode issue or even a hardware
issue for the DS3 card.
