FUNCTIONAL OVERVIEW
In the transmit direction, the P2E3DS3 receives DS3 signals from the customer 
interfaces. Encapsulates the DS3 data flows into standard Ethernet packets, 
(IWF). The Ethernet packets are sent to the cross-connections matrix for 
connection to their provisioned destinations.
In the receive direction, the P2E3DS3 receives Ethernet packets from the 
cross-connections matrix from their provisioned sources. Extracts the DS3 data 
flows from standard Ethernet packets (IWF). The DS3 signals are sent to the 
customer interfaces.
