Router Modules for Expanding Interface, Voice, and WAN Capabilities
Enhance router flexibility with modular interface cards for WAN, Ethernet, security, and voice applications. Compatible with leading enterprise routers.
Flexible Routing with Modular Expansion
Router modules are plug-in hardware cards that expand the functionality of modular routers. These include Ethernet interfaces, WAN ports, DSL modems, firewall accelerators, and voice processing units.Types of Router Modules
- HWIC (High-Speed WAN Interface Cards)
- EHWIC (Enhanced HWIC)
- SM (Service Modules)
- ISM (Internal Services Module)
Use Cases
These modules allow IT teams to deploy tailored connectivity for remote branches, multi-service networks, and secure voice/data delivery. Depending on the router platform (e.g., Cisco 2900 or 4000 series), different module types are supported.Modular Design Benefits
- Upgrade router capabilities without replacing the chassis
- Add new protocols or features as network demands evolve
- Reduce cost through modular scalability
