A metro area network is provided that includes edge and core multiplexors each having a plurality of line ports and one or more uplink ports, a transport network carrying multiplexed traffic between the edge and core multiplexors. In a hard cross connect implementation utilizing source port tagging, a cross-connect device coupled to the core multiplexors provisions or maps communications path between the core multiplexors thereby providing preselected connectivity/mapping of two or more line ports of any of the edge multiplexors. In a soft cross connect implementation utilizing destination port tagging, a cross-connect device includes additional cross-connect multiplexors and functionality to control the destination port tagging performed in the edge, core and cross connect multiplexors thereby provisioning or mapping the desired communications path(s) between various endpoints.
