PVP connections will be re-established automatically when the M770 ATM Switch

directional PVP between 2 ports on different modules (on the same switch) you
must type the command on the CLI of each module.
The command described below will setup a VPL on each <slot.port.vpi> and a PVP
connection joining the two. The PVP connection will be automatically assigned an
ID.
