How do I use the “DCE” and “DTE” settings in the HP Router Configuration Editor “Circuits” menu when using WAN Circuit Type = “HP Point To Point”?
This is confusing terminology in our routers, because the actual meaning of DCE (Data Circuit-Terminating Equipment) and DTE (Data Terminal Equipment) refers to modems and terminals/PCs, where the modem is the DCE device and the terminal or PC is the DTE device. For the router circuit configuration, the terms “DCE” and “DTE” are used to mean “the router at one end” and “the router at the other end”. It doesn’t matter which end is configured as DCE and which end is configured as DTE. What is important is that the routers at each end of an “HP Point To Point” link are not configured with the same “Point to Point Address”. If you ever misconfigure an “HP Point To Point” link with the “Point to Point Address” = DCE at both ends (or DTE at both ends), you will get an error message in the event log: “Invalid Configuration: Pt-to-Pt addresses are equal”. The WAN link will not come up until you correct the “Point to Point Address” on one router so it is a different value from that of the other
