1.Depending on the router model, the primary WAN port can be either G.SHDL or 10/100 FE.

2.FXS = Foreign Exchange Station.

3.DID = Direct Inward Dialing.

4.FXO = Foreign Exchange Office.

5.TBP = trunk bypass.

6.Ports 0 and 1 provide PoE with the optional PoE module installed.

7.The Cisco 880 series ISRs can include an optional PoE module that provides power to 802.3af-compliant devices connected to ethernet ports 0 and 1. If this feature was not configured with the factory order, you must order and install the Field Replaceable Unit (FRU) to enable the PoE function. For this you either need the FRU “800-IL-PM=2” or “800G2-POE-2”. If your device has a separate PoE inlet, use the 800-IL-PM=2, if it has one combined inlet (a description saying “POE OPTION REQUIRES 5A POWER ADAPTOR”), then use the 800G2-POE-2.
