bonding 8 b channels for 512k connect with NM-4B-U on 2811 Router

Pre-purchase assistance and info needed regarding the ability and/or capability of combining the "8 b channels" of 4 ISDN BRI circuits connected to the NM-4B-U Cisco network module and attached to the Cisco 1811 Router. Need to have 512k aggregate bandwidth connection through ONE connection profile using ISDN dialup to the WAN (internet provider) Has been very difficult to secure both hardware and information concerning what is almost an obsolete technology, yet this is the ONLY means available from this location that is feasible. Would appreciate any input regarding this issue, specifically if this is in fact possible, and if any special additional considerations are necessary for implementing this configuration. Thanks.

hi

i would like to suggest to create single dialer interface and bind all your physical bri interface in that using dialer pool member command.

Also chek out for the dialer load threshold limit also in your dialer interface so that even minimum load can trigger the isdn lines out..

we have sucessfully tried running/bundling 3 physical interfaces and achieved 384K.hope there shuldnt be any probs with 4 links..

do check this link which deals with 2 physical interface which can be referred to bundle all you 4 interfaces.
