I currently have a point-to-point T1 circuit between 2 3662 routers. 6 of the channels of the T1 circuit are multiplexed for voice to our phone system. We are using the T1 multiflex cards for this. I want to be able to add a 2nd T1 circuit and use multilink PPP to bond them together. Does anyone know if I can multilink the new T1 and the existing T1 - even with the voice channels?
Multilink PPP with interleaving is used in conjunction with weighted fair queuing and RSVP or IP precedence to ensure voice packet delivery. Use Multilink PPP with interleaving and weighted fair queuing to define how data will be managed; use RSVP or IP precedence to give priority to voice packets.For more information on this please refer the following document.
