Figure 1-25, Figure1-26, and Figure 1-27 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- 26 lists the maximum number of calls that is
supported when the codec complexity command is configured for Flexible, Medium or High complexity.
1Primary WAN port1—G.SHDSL
1. Depending on the router model, the primary WAN port can be either G.SHDL or 10/100 FE.

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, 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.
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.
