Re: Understanding Question - FRTS or MQC or Both

well this may or may not help, cause i stay confused on this topic myself...

the thing about this for me is also with not so much if they tell you to not
use one or the other, but it is hard enough that it has changed so much over
the course of going from FRTS to FRTS and CBTS and then still using the
MAP-CLASS to do the fragmentation instead of doing it at the interface
layer...

and now with 12.4T(20) and the HQF it seems you do not need the map-class at
all anymore as all, some or most (whichever the case maybe0 the functions
have been moved into the MQC...

http://www.cisco.com/en/US/prod/collateral/iosswrel/ps6537/ps6558/white_paper_c11-481499.html

then just when i think i know the way it is going and understand a litle
bit, i find this command 'shape fr-voice-adapt' and look in the command
reference and see this example with the fragmenation configured on the
interface:

Examples
The following example shows the configuration of Frame Relay voice-adaptive
traffic shaping and fragmentation. With this configuration, priority-queue
packets or H.323 call setup signaling packets destined for PVC 100 will
result in the reduction of the sending rate from CIR to minCIR and the
activation of FRF.12 end-to-end fragmentation. If signaling packets and
priority-queue packets are not detected for 50 seconds, the sending rate
will increase to CIR and fragmentation will be turned off.
