Product Description
The Adtran 12007640 Atlas 550 Quad BRI ST Module is a specialized interface card designed for the Adtran Atlas 550 platform, enabling the termination of four Integrated Services Digital Network (ISDN) Basic Rate Interfaces (BRI). ISDN BRI is a digital telecommunications standard that provides two 64 kbps bearer channels (B-channels) for voice or data, and one 16 kbps data channel (D-channel) for signaling and control. This module specifically uses the ST connector type, which is part of the ISDN S/T interface standard, allowing for direct connection to ISDN network termination equipment or other ISDN devices. This module is crucial for applications requiring digital voice trunking or high-speed data connectivity over ISDN lines. It allows businesses to connect their PBX systems to the public telephone network for digital voice calls, or to establish dedicated digital data links for remote access, VPNs, or other data-intensive services. The Quad BRI configuration offers significant capacity for smaller to medium-sized branch offices or specific departmental needs that utilize ISDN technology. As part of the Adtran Atlas 550 series, this module integrates seamlessly into the platform, providing a robust and reliable solution for ISDN connectivity. The ST interface is particularly useful for connecting to the network side of an ISDN installation or for creating multi-device ISDN bus configurations. It represents a key component for organizations that continue to rely on or deploy ISDN services for their communication infrastructure.
