Chapter 1 Product Overview
Cisco 880 Series ISRs
Cisco 881-V, Cisco 887VA-V, and Cisco 887VA-V-W
Figure 1-15, Figure 1-16, and Figure 1-17 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. Ta ble 1-7 lists the maximum number of calls that is
supported when the codec complexity command is configured for Flexible, Medium or High complexity.
Note Configuring the codec complexity setting to support secure calls uses DSP resources, but does not affect
the maximum number of supported calls.
Figure 1-15 shows the front panel details of the Cisco 881-V, Cisco 887VA-V, and Cisco 887VA-V-W.
