Comprehensive WAN Support
The Cisco 1721 and 1720 support up to two of the WICs listed in Table 3. These WICs support a wide variety of
WAN technologies: Integrated Services Digital Network (ISDN), asynchronous serial and synchronous serial such as
leased lines, Frame Relay, ADSL, G.shdsl, Switched 56, X.25, and Switched Multimegabit Data Service (SMDS), and
single-port Ethernet. Also available are WICs that integrate a DSU/CSU into the Cisco 1721 and 1720, eliminating
the support costs and complexity of deploying and managing external devices.
