17. The device of claim 11 , wherein the downstream VLAN and the upstream VLAN operate on the same physical Local Area Network (LAN).

18. A telecommunications node, comprising:

a communications interface that is configured to transmit and receive data packets over a telecommunications network; and

at least one hardware processor interoperably coupled with the memory and configured to:

receive, over a first VLAN, a downstream message from a root node of a first ring network;
