AudioCodes Mediant 1000B LAN Extension Module – 4-Port Switch with Active/Standby Redundancy for Mediant 1000B (M1KB-VM-SWX)

The AudioCodes M1KB-VM-SWX is the LAN Extension Module (SWX) for the Mediant 1000B modular VoIP gateway. It adds a 4-port LAN switch with active/standby redundancy directly to the Mediant 1000B chassis, expanding the gateway's LAN interface capacity and enabling redundant network connectivity. It is designed for Mediant 1000B deployments that require additional Ethernet switching capability or network interface failover within the chassis itself.

The Telecom Spot Take

The SWX module is for Mediant 1000B deployments where LAN connectivity and redundancy requirements go beyond the base chassis Ethernet ports. By adding four switched LAN ports with active/standby failover directly inside the chassis, it simplifies the network architecture — you can connect multiple network segments or provide redundant uplinks without external switches. For enterprise environments with high availability requirements, the active/standby configuration means a network interface failure doesn't take the gateway offline. This is the right module when the Mediant 1000B needs to serve as a more complete network edge device rather than just a gateway behind a separate switch.

Key Features

• 4-port integrated LAN switch — expands Mediant 1000B Ethernet connectivity within the chassis
• Active/standby redundancy — automatic failover if the active LAN interface fails
• Simplifies network architecture — eliminates the need for an external switch for LAN port expansion
• High-availability deployment support — redundant LAN connectivity for mission-critical gateway environments
• OEM Mediant 1000B voice module — installs in the Mediant 1000B expansion bay alongside other voice modules
