Description
The AudioCodes Mediant 1000B with 2 E1/T1 Spans (M1KB-D2) is a modular, enterprise-grade media gateway designed to deliver reliable voice connectivity for unified communications, SIP trunking, and TDM-to-VoIP environments.
This configuration includes the Mediant 1000B chassis, an Active/Standby pair of Gigabit Ethernet interfaces, and one module supporting 2 E1/T1 spans—providing high-availability redundancy and flexible voice deployment options.
The chassis supports expansion with additional Mediant 1000 Voice modules such as FXS, FXO, BRI, or additional T1/E1 interfaces, allowing organizations to scale capacity as requirements grow. For further GE redundancy, the M1KB-SWX module can be added to provide two additional Active/Standby GE interface pairs.
