Functional Description
The core of RLH-TG Mux is the TDM/Packet processing unit. It truncates T1/E1 data stream, putting the
data into Ethernet packet with or without IP headers. The packets are passed to the Ethernet switch unit
via MII interface, and are sent out adaptive the uplink ports. Ethernet data from two local data port are
also sent out through the uplink ports, but with lower priority than those packets containing T1/E1T1/E1
data.
