Bonded T1 Lines, Bonded DS1 Lines, Bandwidth, Broadband, Bonded T-1 Service and Satellite TV via DirecTV 01
A bonded T1 (also called DS1) is two or more T1s that have been joined (bonded) together to increase bandwidth. A full T1 provides approximately 1.5Mbps or 24 individual channels each of which supports 64Kbit per second, where two bonded T1s provide 3Mbps or 46 channels.
Two bonded T1s allow you to use the full bandwidth of 3Mbps where two individual T1s can still only use a maximum of 1.5Mbps at one time. To be bonded the T1 must run into the same router at the end, meaning they must run to the same ISP.
PPP is more stable than the older SLIP protocol and provides error checking features. Working in the data link layer of the OSI model, PPP sends the computer's TCP/IP packets to a server that puts them onto the Internet.
MPPP is short for MultiLink PPP, an extension of the PPP that allows the B-channels of ISDN lines to be used in combination as a single transmission line, doubling throughput to 128 Kbps. MLPPP is also referred to as MPPP, MLP and channel bundling.
