BONDING

BONDING is a new protocol standard from the Bandwidth ON Demand INteroperability Group for combining the bandwidth of several 56 kbps or 64 kbps channels. BONDING can ‘bond’ from 2 to 31 channels at once. The high speed data, which must be a multiple of 56 kbps or 64 kbps, is split after arrival at the DTE interface into the various channels. On the opposite end the data is recombined into the original data stream and sent to the DTE interface.

BONDING ON THE UTA220

		Because the UTA220 supports one ISDN basic rate interface
		(2B+D), two simultaneous calls can be made, allowing an
		effective bandwidth of 112 kbps or 128 kbps. The BONDING
		call can be made from port 1 or port 2. Table 10-1 lists
		BONDING call options.

CONFIGURATION /		Set to 2 in order to request a 112 kbps or 128 kbps call.
PORT /		Set to 1 in order to request a 56 kbps or 64 kbps call.
BONDING OPTIONS /		Note: To run 56 kbps or 64 kbps, it is simpler to use

		clear channel transfer (select PROTOCOL: NONE). If
		you request a rate multiplier of one, it will negotiate
		parameters according to the BONDING specification
		at the start of the call and then switch to a 56 kbps or
		64 kbps clear channel call.
CONFIGURATION /		This option is needed only for AT&T 5E5/5E6 lines. If

		call on port 2, set both port 1 and port 2 to 1. This will
		cause both directory numbers to be used for the two
		channel BONDING call.
