AudioCodes Mediant 1000B Pre-Configured VoIP Gateway – 6-Span T1/E1, High-Density SIP Trunking Chassis (M1KB-D7)

The AudioCodes M1KB-D7 is a pre-configured Mediant 1000B modular VoIP gateway with six T1/E1 digital spans installed. At six spans, it supports up to 144 simultaneous T1 channels or 180 E1 channels — making it a high-capacity TDM-to-SIP trunking solution in a single chassis. The "D7" designation indicates this is a factory-configured bundle, shipped ready for deployment without requiring separate blade installation and configuration steps.

The Telecom Spot Take

Six T1 spans is substantial TDM capacity — 144 simultaneous calls on T1, or 180 on E1. This is the configuration for large contact centers retiring a TDM PBX while keeping PSTN access through existing T1/E1 circuits, or for service providers running TDM-SIP interconnect at high density. The pre-configured D7 bundle means the gateway ships ready to rack and connect: blades are installed, the chassis is assembled, and the specific configuration is validated at the factory. This reduces deployment time compared to purchasing individual blade modules and a base chassis separately. For organizations that know their TDM span count upfront and want a turnkey high-density gateway, the M1KB-D7 delivers six spans in a fully assembled, ready-to-deploy package.
