The cables are single segments. That is, the cables original in a port of the Verizon (Westell) modem/router and terminate at the port of a Meraki gateway. The wires are wired IAW EIA###A - straight through connectorization. However, Meraki tech sup states that its gateways are self-configuring - the wiring - EIA###A or EIA###B - doesn't matter!!!
I've searched on the i-net for issues with these modem/routers - no go - nada, zip, zilch, nichts!!! I think the next step is getting Verizon on the line to see what's what.
I appreciate your interest and suggestions. I'll let you know what I find out!!
