We have two routers 2610 doing bridging. These have 4E1 with 2Mb apiece. The client demand that so single works with 2Mb when in theory must have until 8Mb.

It can be a configuration problem, it is possible that bug exists affecting the equipment?

Re: We have two routers 2610 doing bridging. These have 4E1 with

If you have four E1s set up and your clients are getting only 2MB/s of throughput (one E1), you likely have set them up as four seperate bridged connections. This is a valid configuration, but won't do what you want, because three of them will be shut down by spanning-tree. In a bridged topology, the spanning-tree protocol will ensure there is exactly one path between two points by shutting down redundant links (putting them in a "blocking" state). You can confirm this with "show spanning-tree blocked", three of your E1 interfaces will probably be listed.

Try using multilink PPP to bundle all four E1s together into a single virtual interface with 8MB/s of bandwidth. The URL below documents how to set up multilink and then to set up bridging on the combined virtual interface.

If you configured your cisco to work as a bridge in addition to "bridge-group 1" parameter in your serial interface use the "bridge-group 1 circuit-group 1" parameter added in your every serial interface that is connected to E1 line, The parameter will expected to aggregate your E1links and at the same time redundancy
