Description
The AudioCodes Mediant 1000B M1KB-2AC is the high-availability version of the Mediant 1000B chassis — the same 6-bay modular platform as the base M1KB, but with dual AC power supplies installed from the factory for active/standby power redundancy. No voice modules are included; this is the chassis foundation you build on by adding the voice module cards that match your specific T1/E1, BRI, or analog port requirements. For any deployment where power supply failure cannot mean gateway downtime, the M1KB-2AC is the correct starting point.
The Telecom Spot Take
In enterprise voice infrastructure, dual power supplies are not a luxury — they're the difference between a planned maintenance window and an unplanned outage. The Mediant 1000B M1KB-2AC ships with both AC power supply bays populated, so the chassis operates in active/standby power mode from day one. If either supply fails, the other takes the full load without any interruption to voice traffic. Pair this chassis with AudioCodes T1/E1 voice modules (M1KB-VM-1SPAN through M1KB-VM-4SPAN) to build out a gateway with the exact span count and channel capacity your organization needs — anywhere from a single T1 up to six spans and 192 voice channels in a single 1U unit. Two GE ports provide network redundancy options at the interface level as well.
Key Features
- Dual AC power supplies: Factory-installed active/standby redundant PSUs — if one fails, the other carries the load without any voice service interruption.
- 6 voice module expansion bays: Accepts AudioCodes M1KB voice modules (T1/E1, BRI, FXS/FXO, analog) for fully customizable port configuration.
- 2 Gigabit Ethernet ports: Dual 10/100/1000Base-T network interfaces for SIP connectivity and optional interface redundancy.
- Up to 192 voice channels: Fully populated with T1/E1 modules, the chassis scales to 192 simultaneous voice channels in a 1U form factor.
- Multi-service platform: Supports E-SBC, VoIP gateway (TDM-to-SIP), and hybrid configurations — functions are determined by licensed software and installed modules.
- 1U rack-mountable: Standard 19-inch rack mounting with rear cable management for clean data center and wiring closet installation.
- SIP, H.323, and MGCP: Broad protocol support for compatibility with any enterprise VoIP platform or SIP trunking provider.
