    while trying to run a site-to-site VPN for a corporation, connection is performed across telephone lines (copper CAT 1 cables) through Internet if DSL is applied. During DSL connection, should we need devices such as CSU/DSU (for digital to digital translation)? Then, in these type of connection, should corporation router have
    synchronous serial link going to each branches "additionally?

    Withoug sounding unhelpful, you may want to go a read up on the serial connectivity side of things again. if at first it doesnt sink in then read it again....and again...and again...and again...and again...and again...and again...and again...and again...and again...and again... :biggrin

    If you have a DSL connection at the customer site then they will need a DSL modem, or a router with a built in DSL modem, a DSU/CSU is used on leased lines.
