i am expanding from 1.5 to 3 meg wan pipe. verizon says I do not need additional dsu/csu and no other additional equipment is needed. still they are asking for the demark which makes me believe they plan to come on site for something. won't I need additional equipment or can a single T1 be cranked up to 3 meg without any additional equipment and/or on site technical visit?
