A company that establishes a company network needs to connect to a wide area network. The bandwidth of the connection is required to be greater than 1Mbps . Which of the following interfaces and protocols are available ? (Multiple choice)

AV35 protocol interface and cable, using PPP as the link layer protocol

BV35 protocol interface and cable, using Frame Relay as the link layer protocol

C. PRI interface and cable, bundle multiple time slots, use PPP as the link layer protocol

D. BRI interface and cable, bundle multiple time slots, use PPP as the link layer protocol.

Answer: ABC

Explanation:

V . 24 Support same and asynchronous: asynchronous maximum rate 115kbps synchronous maximum rate 64kbps

V . 35 only supports synchronization: the highest rate is 2048000bps = 2Mbps

Two access methods of ISDN :

BRI interface → 2B + DB channel 64kbps D channel 16kbps maximum rate 144kbps

PRI interface → E1 30B + D maximum rate 2Mbps T1 23B + D maximum rate 1.544Mbps
