Improving on the success of the Cisco 3600 Series' modular architecture, this highly integrated platform delivers a compelling value proposition with by integrating components previously purchased separately, such as two fixed 10/100 LAN ports and additional memory. With the options of two or four network module slots - which can be adjusted to accept the HDSM modules - three WAN Interface Card (WIC) slots, and two on-board AIM slots, the Cisco 3745 offers many flexible options to enable high densities of services.
