We (Sun and BARRNet) have found that the two interoperate without problem using 56KB lines but do not work at all using a T-1 line. When we tried connecting the two over a T-1 line, the Sun end sees a CRC error for every packet that the cisco sends while the cisco sees nothing in return. Can someone describe the T1 PPP framing used by the cisco implementation? Any hints or suggestions would be appreciated. Thanks, --Vince
