I have some problems with the module WIC-1SHDSL-v2, I have two SDSL connection (Germany's DTAG), they work perfectly over a SDSL modem and pppoe-client configuration on the Cisco, I'm able to configure them as a bundle of 2 SDSL and get so 4Mbit.
we're testing now the module WIC-1SHDSL, it has 4 wire-support, it means I can connect 2 SDSL lines into it (via funny RJ-11 Y-form cable)
it works well, I could configure it, have activated ATM's PVC and PPPoE over it and it comes online - but only with 2Mbit, it means only one SDSL is active.
Somewhere I read that DSLAM should support such a configuration with 2 SDSL over the ATM PVC, but what exactly schould be change on the DSLAM? additional ATM PVC? I'm a little bit lost.
