Inline Multilink PPP, Multilink Frame Relay, and Multilink Frame Relay End-to-End for time-division multiplexing WAN interfaces

This feature allows support of Inline Multilink PPP (MLPPP), Multilink Frame Relay (FRF.16), and Multilink Frame Relay End-to-End (FRF.15) for time-division multiplexing (TDM) WAN interfaces provide bundling services through the Packet Forwarding Engine without requiring a PIC or Dense Port Concentrator (DPC). Traditionally, bundling services are used to bundle multiple low-speed links to create a higher bandwidth pipe. This combined bandwidth is available to traffic from all links and supports link fragmentation and interleaving (LFI) on the bundle, reducing high priority packet transmission delay. This support includes multiple links on the same bundle as well as multiclass extension for MLPPP. Through this service you can enable bundling services without additional DPC slots to support Service DPC and free up the slots for other MICs. For connecting many smaller sites in VPNs, bundling the TDM circuits with MLPPP/MLFR technology is the only way to offer higher bandwidth and link redundancy.
