Used and Refurbished Cisco Modem Modules

The used Cisco modem modules significantly enhance the dial access flexibility and scalability of the used Cisco router platforms. Each network module supports up to 30 digital modems. The refurbished Cisco modem modules use either the single or dual PRI network modules to offer support for up to 60 remote modem users (using two network modules), at speeds up to 56 Kbps. K56flex modem technology is currently supported, and future standards will be supported as they become available.
