At , a typical full-length 1,500 byte Ethernet frame would take 77.42 μs to transmit. On a lower-speed T1 line, the same packet would take up to 7.8 milliseconds. A queuing delay induced by several such data packets might exceed the figure of 7.8 ms several times over. This was considered unacceptable for speech traffic.
