The Cisco NME-16ES-1G is an EtherSwitch service module that is made to work with the Cisco series of Integrated Services Routers. The inferface card modules are designed to bring affordable solutions and reduce the cost of ownership by combining switch ports with a router. Integrating these services in a single device allows administrators or managers to easily control one switch that uses the router command line interface for wide or local area network management. Because using one device reduces the complexity of a network, enterprises can reduce their training and maintenance expenses and save on new equipment purchases. This refurbished Cisco NME-16ES-1G EtherSwitch module expands the capacity of switching within Cisco products by allowing for additional support. The Cisco high-speed WAN card also offers Layer-3 switching and ensures access to the Cisco Network Assistant. The assistant is an embedded feature that provides end users with access to a suite of software. The software is also designed for ease of use and is designed along the lines of a familiar Web browser. For security, the NME-16ES-1G-P module works directly with a Cisco router and provides secure network solutions from one platform. Internet protocol phones work within the network and bring end users a number of benefits. The Cisco Communications Manager Express allows call processing for the phones and validates the credentials of an individual device. Once the device has been validated, the Cisco high-speed WAN card automatically transfers it to the appropriate network. As data leaves the end user, the router can also encrypt it to enhance security and allow for communication between branch offices and their managers at a centralized location. Since this Cisco HWIC module brings a high level of convergence, it improves network architecture and allows branch office services to be conducted in the most cost-effective manner. directly with a Cis
