Description
The AudioCodes Mediant 1000B M1KB is the base chassis that everything else in the Mediant 1000B ecosystem builds on. It ships as a bare chassis — no voice modules installed — with six expansion bays, two Gigabit Ethernet ports, a single AC power supply, and the embedded hardware platform that supports Mediant 1000B's full range of gateway and E-SBC software functions. Add AudioCodes voice modules to configure the exact T1/E1, BRI, FXS/FXO, or analog port mix your deployment requires, and scale capacity incrementally as your needs grow.
The Telecom Spot Take
The Mediant 1000B chassis is one of the most flexible 1U voice gateway platforms in the enterprise market. Because it's fully modular, a single chassis can serve as a pure T1/E1 digital gateway, an analog port gateway, a mixed digital/analog gateway, or a full Enterprise SBC — the role is defined by the voice modules you install and the software license you activate. Organizations use the base M1KB when they want to populate the chassis to their own spec, buying only the voice modules they need now and adding capacity later without replacing the chassis. The embedded CPU, dual GE interfaces, and power supply are all enterprise-grade from the start. For deployments requiring power supply redundancy, pair this chassis with an additional M1KB-PS-AC or step up to the M1KB-2AC for a factory-configured dual-PSU unit.
Key Features
- 6 voice module expansion bays: Accepts any combination of M1KB voice modules — T1/E1 spans, BRI, FXS/FXO analog, DSP processing — to match your exact port requirements.
- 2 Gigabit Ethernet ports: Dual 10/100/1000Base-T network interfaces for SIP trunking, management, and optional interface redundancy.
- Up to 192 voice channels: Fully populated chassis scales to 192 simultaneous voice channels in a single 1U unit.
- Multi-service capable: Runs as VoIP gateway (TDM-to-SIP), E-SBC (session border controller), or hybrid — configured via software licensing.
- SIP, H.323, and MGCP: Full multi-protocol support for interoperability with any enterprise VoIP platform or SIP trunking provider.
- 1U rack-mountable: Rack-mount ready for standard 19-inch equipment racks.
- Redundant PSU option: Add a second M1KB-PS-AC for active/standby power redundancy without replacing the chassis.
- Incremental scaling: Start with the modules you need today; expand by adding voice modules to empty bays as requirements grow.

Frequently Asked Questions
- Does the M1KB include any voice modules?
- No. The M1KB is a bare chassis — it includes the housing, power supply, CPU, GE ports, and fan tray, but no voice modules. You select and purchase the voice modules (T1/E1 spans, analog ports, etc.) separately to configure the gateway for your specific needs.
- Can I add a second power supply to the M1KB later?
- Yes. The M1KB includes a second PSU bay that accepts the M1KB-PS-AC AC power supply module. Adding a second supply provides active/standby power redundancy without replacing the chassis. Alternatively, the M1KB-2AC ships with both PSU bays populated from the factory.
- What voice modules are compatible with the M1KB?
- The M1KB accepts AudioCodes M1KB voice modules including M1KB-VM-1SPAN (1 T1/E1), M1KB-VM-2SPAN (2 T1/E1), M1KB-VM-4SPAN (4 T1/E1), M1KB-VM-MPM (media processing), and M1KB-VM-SWX (LAN extension). Contact The Telecom Spot for a complete compatibility list for your use case.
