Why do we need Inverse Multiplexing?

Why do we need Inverse Multiplexing?

• An organization wants to send data, voice and video each of which requires a different data rate
• To send voice it needs 64Kbps,
• To send data, it needs 128 Kbps link
• To send video it may need 1.544 Mbps link
• It can lease a 1.544 Mbps line from a common carrier and only use it fully for sometime
• Or it can lease several separate channels of lower data rates
• Voice can be sent over any of these channels
• Data & Video can be broken into smaller portions using Inverse Multiplexing and TX
