Routing, Switching and VOIP, Based on CISCO 5915 Embedded Service Router (ESR)

Klas VoyagerESR 1.0

VoyagerESR integrates a Cisco 5915 ESR with a Klas-designed switch that extends the router’s capabilities to provide additional interfaces and features while minimizing module size, weight and power. VoyagerESR expands the two routed and 3 switched ports of the Cisco 5915 ESR to provide 2 routed ports and 12 switched ports, 4 of which have PoE. VoyagerESR also provides removable eToken-like configuration storage along with support for cellular/wireless, serial and FXS. Ruggedization is a key feature with a lightweight, milled aluminum enclosure and dustcaps for all ports.

Cisco Discovery Protocol

Expanding the Cisco 5915 base functionality while maintaining an integrated IoS-centric approach is a key feature of VoyagerESR. Cisco Discovery Protocol provides easy integration with a Cisco VoIP network with support for VLAN and QoS features. In addition troubleshooting is made easy using CDP commands on VoyagerESR.

Key Features:

  • Cisco 5915 ESR and Klas-designed switch in a rugged, milled aluminum enclosure
