VWIC2-2MFT-G703, cRTP and Multilink

Unanswered Question
Feb 4th, 2010


I wish to know if it is possible aggregate 2 E1/G703 data link in order to increase bandwidth up to 4 Mbps (2x 2 Mbps) with the card VWIC2-2MFT-G703, by using ppp encapsulation with the multilink feature.

I have read several documents and according to them, I conclude that this setup is possible but I can not test it.

Does somebody can confirm that such setup is possible ?

With the same idea, with 2 cards (VWIC2-2MFT-G703) is it possible to get 8 Mbps (2x 2 Mbps per card) ?

I will use 18xx or 29xx routers.

Next, with this setup, I whish to enable cRTP.

I suppose that I can enable this feature on the Multilink interface with something like that:


interface Mutlilink <group-number>

ip address <address> <mask>

encapsulation ppp

ppp multilink

ip rtp header-compression ...


Does somebody can confirm that cRTP is available with such setup (multilink with VWIC2-2MFT-G703 card) ?

Thanks for your Help.

I have this problem too.
