DTE
Data terminal equipment. A device at the user end of the interface between the network
and the user. The DTE connects to a data network through a data communications
equipment (DCE)—such as a modem or an interface card. DTEs convert user information
into data signals for transmission, and reconvert received data signals into user
information. Compare

DTR
Data Terminal Ready. The circuit that is activated to inform the data communications
equipment (DCE) when the data terminal equipment (DTE) is ready to send and receive
data. See also
DCE ; DTE .

E
E1
Digital WAN carrier facility used predominantly in Europe that carries data at a rate of
2.048Mbps. E1 lines can be leased for private use from common carriers. Compare

easy-multihome
A specialized, predefined BGP policy that simplifies the use of PortMaster routers in
straightforward multihomed environments. When you define easy-multihome for a peer,
you restrict what the PortMaster handles from the peer to information that is no more
than two autonomous system hops away from the PortMaster. Only information that
meets this criterion is accepted from the peer, put into the routing table used to forward
packets to their destinations, and advertised to other peers. If you define easy-multihome
for a peer, you must also define a default route on each router in your autonomous
system to point them to destinations more distant than two hops. See also
