Frame Format
The Ethernet frame sent by the IPmux-1 is a UDP datagram that transfers E1/T1
payload bytes over IP over Ethernet (UDP payload + UDP header + IP header +
Ethernet header).
The UDP payload size is equal to TDM bytes per frame (TDM bytes/frame
configuration).
Table 1-2 specifies the structure of the different headers, special fields, and the
payload in the Ethernet packet.
