The 25 Mbps interface operates at 25.6 Mbps over twisted pair cables, compliant with ATM Forum UNI specifications. Cell delineation Cell delineation is performed using the 4B5B codes. A sync event timing marker is sent at the next octet boundary after an incoming sync signal is detected. The sync event has priority over all line activity.
Line coding Line coding has the capability to be disabled.
All 53 bytes of the cell are encoded prior to transmission. Reception of any other command is an error and can cause cell discard. A 100 Ohm resistive load is required.
