same order in which they were transmitted, and the reconstructed packet is sent on to the recipient’s networking equipment.

From the point of view of the routers or other devices connected to the inverse multiplexers, they are communicating via a single high-speed WAN channel at some multiple of the SDSL or IDSL rate. This is especially important when an application’s bandwidth requirements are high. But a high bandwidth service is either difficult to obtain or too expensive. Some examples include: a university offering remote educational services, or distance learning, may require very high bandwidth across the WAN in order to maintain acceptable quality for its classroom video. Bringing together relatively less expensive, lower speed SDSL or IDSL circuits to form a single high-speed link often saves a company a significant amount money. The savings can pay for the inverse multiplexer in a few months.

Netopia DSL Bonding

Netopia’s DSL Bonding implementation is based on a technique used in Copper Mountain Networks CopperEdge DSL Access Concentrators. Copper Mountain’s approach conforms with the Multi-link Frame Relay (MFR) protocol. However, where DML operates between the CPE and DSLAM, MFR would more likely operate between the CPE and Frame Relay terminator (potentially the ISP’s router).

Currently, the D-Series equipment does not support the potential use of more than one ISDN U-BRI channel for switched ISDN applications – the additional BRIs available on a single or dual WAN module configuration can only be bonded to the first BRI in IDSL DML mode.

The Copper Mountain approach allows the bonding of multiple physical DSL links into a single logical channel. The logical channel may use RFC1483 FUNI, RFC1490 and/or Q.922 Frame Relay, or RFC1661/1662 PPP data link encapsulations. In addition, the physical links support Copper Mountain’s control protocol (CMCP).
