we have a new connection to an external client
a new T1 router has been delivered to our premisses
the router is than connected to a switch (the above was done by a third company)
we now need to connect this connection to our network, we only have 1 core switch)
what is the best way to connect this to our network, and whatt info do we need from this vendor as they didnt supply any info on this switch that connects to the t1 router?
