Configure the dialer bandwidth. The dialer interface has a default bandwidth of 56 kbps, which may be less than the upstream bandwidth of your digital subscriber line (DSL) connection. You can find the upstream bandwidth of your DSL connection by entering the show dsl interface atm0 command in dialer interface configuration mode. If you have two or more PVCs sharing the same DSL connection, the bandwidth configured for the dialer interface must be the same as the bandwidth allocated to its assigned PVC
