Data circuit-terminating equipment (DCE) is a device that connects to the leased line provided by the telco. The term circuit-terminating refers to the fact that a leased line is sometimes called a data circuit, or simply a circuit, and the CSU/DSU sits at the end of the circuit. The DCE also provides clocking to the data terminal equipment (DTE). The DTE is a device that needs to send data over a circuit. Routers act as DTEs because they need to send IP packets, encapsulated in data link frames, over WAN links.

What DTE devices are used on WAN and what DCE devices are used on WAN?
DTE devices in the sense we have PC (Computers), router,Serial Printers, PLC's, Video Cameras, Video Recorders, Video Editors like this we use any of them depending on our requirementDCE devices in the sense hub,bridge,switch,modem etc are dce devices we usei hope it is useful to you........
What are serial interfaces on a router typically used to connect?
a serial interface on a router is basically used for WAN communications. we generally connect to other routers through internet using serial interface. In a lab scenario we generally emulate WAN connections by connecting the serial interfaces of the routers using a cable called DCE/DTE cable.
Router port that connects a wan link?
Data Terminal Eqipment (DTE)
Which device encodes data for transmission across the WAN service provider transmission link?
DCE
What two devices are responsible for converting the data from the WAN service provider into a form acceptable by the router?
a modem a DTE device
What is the network that links lan and wan?
The Internet links LANs and WANs together.
What wan link is the most reliable?
Core links should be the fastest and most reliable leased lines in the WAN
What is the default WAN protocol for Cisco serial links?
HDLC
How can a Lan become a Wan?
if the LAN is connected to another LAN over a wide distance using point to point links then it becomes part of the WAN (but it doesn't become a WAN by itself).
What are some types of point-to-point WAN links?
Dds t1 t3
Which subnet prefix is most effective for point-to-point WAN links?
/30
What traffic does intersite replication use to reduce the impact to bandwidth on coporate wan links?
Replication between sites is compressed to optimize WAN bandwidth utilization.
