Explain how the serial connection to a WAN service provider differs from the way the serial connections are set up for the curriculum labs

What will be an ideal response?

The Data Communications Equipment (DCE) is a device that supplies the clocking services
to another device. Typically, this device is at the WAN access provider end of the link.
Data Circuit-Terminal Equipment (DTE) is a device that receives clocking services from
another device and adjusts accordingly. Typically, this device is at the WAN customer or user
end of the link. A router is considered a DTE device.
In the lab setting, there is no service provider. The routers are connected back to back.
Therefore, one router will act as the DCE and uses a DCE cable. This router will provide the
clocking that is usually provided by the service provider's equipment.
