Pre-owned, used and refurbished Cisco CISCO1720-ADSL

The CISCO1720-ADSL modular access router provides faster data transmission through use of ADSL (asymmetric digital subscriber line), processing traffic on frequencies not utilized by voice telephone calls. End-of-lifed in 2003, we carry new and refurbished CISCO1720-ADSL that can provide investment protection to small and medium businesses as well as excellent performance and security. The CISCO1720-ADSL also offers optional integrated firewall, NT-1 for ISDN, VPN tunnel server and DSU/CSU. Driven by RISC architecture, the CISCO1720-ADSL offers superior secure data access and the ability to add new WAN services in the future.

All pre-owned CISCO1720-ADSL equipment is tested to factory specifications and is guaranteed to arrive safely.
