Examples: Configuring a Single Fractional T1 Interface Using FRF.12

FRF.12 with Fragmentation and Without LFI

This example shows a 128 KB DS0 interface. There is one traffic stream on ge-0/0/0, which is classified into queue 0 (be). Packets are fragmented in the link services IQ interface (lsq) according to the threshold configured in the fragmentation map.

FRF.12 with Fragmentation and LFI

This example shows a 512 KB DS0 bundle and four traffic streams on ge-0/0/0 that are classified into four queues. The fragment size is 160 for queue 0, queue 1, and queue 2. The voice stream on queue 3 has LFI configured.
