Depending on the router model, the primary WAN port can be either G.SHDL or 10/100 FE. 2. Ports 0 and 1 provide PoE with the optional PoE module installed. 3. 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, SKU 800-IL-PM-2, you must order and install it to enable the PoE function. The PoE power supply, SKU 800-ILPM-4, is also required. Caution The primary WAN port on all 888E models is designed for an RJ-45 connector only. Damage to the primary WAN port may occur if a non RJ-45 connector is inserted. Cisco 881-V, Cisco 887VA-V, and Cisco 887VA-V-W Figure 1-13, Figure 1-14, and Figure 1-15 show the features available on the Cisco 881-V and Cisco 887VA-V routers. The features available vary, depending on the router model. Some features may not be available on your router. The Cisco 881-V and Cisco 887VA-V voice and data series gives you the flexibility to use either FXS or BRI voice ports. However, the number of concurrent calls that can be supported by the router is limited by the codec complexity setting on the router. Table 1-3 lists the maximum number of calls that is supported when the codec complexity command is configured for Flexible, Medium or High complexity.
