The T-carrier standards, also called T-CXR standards, utilize what type of multiplexing over two wire pairs to create multiple channels?

DSL services require many subscribers to share the same local line, causing potential security concerns. T/F

DSL signals travel over telephone lines using the 300 to 3300 Hz frequency range. T/F

With a SIP trunk, what is the only limitation on the number of calls that can run at any one time?

What type of virtual circuit allows connections to be established when parties need to transmit, then terminated after the transmission is complete?

Although MPLS can operate over Ethernet frames, it is more often used with other Layer 2 protocols, like those designed for WANs.

What OC level is primarily used as a regional ISP backbone, and occasionally by very large hospitals, universities, or other major enterprises?

WANs connect nodes, such as workstations, servers, printers, and other devices, in a small geographical area on a single network.
