ISDN 2B1Q specifications
ADTRAN ISDN 2B1Q technology is a digital transmission method that enables high-quality voice and data communication over traditional copper telephony lines. It is particularly notable for its ability to utilize the existing infrastructure of Plain Old Telephone Service (POTS) while providing enhanced features found in integrated services digital networks (ISDN).The acronym 2B1Q stands for two binary one quaternary, which highlights the modulation scheme employed in this technology. It effectively combines two bits of data into a single symbol that can convey more information than a traditional binary system. This modulation method allows for the transmission of two 64 Kbps B channels alongside one D channel, which has a signaling speed of 16 Kbps. Consequently, the ISDN 2B1Q configuration provides users with the capacity for simultaneous voice and data transfers, greatly enhancing productivity and connectivity.
One of the primary features of ADTRAN ISDN 2B1Q is its ability to deliver multiple calls simultaneously. This is achieved through the two B channels, which can each support voice or data calls independently. Moreover, the D channel is responsible for managing call setup, signaling, and control, freeing the B channels to maintain the active communication sessions without interruption.
Another significant characteristic of ADTRAN ISDN 2B1Q is its support for various applications, including video conferencing, file transfers, and remote access. This versatility makes it an ideal solution for small to medium-sized businesses that rely on efficient communication systems for collaboration and operational efficiency.
ADTRAN’s approach to ISDN technology also emphasizes reliability and quality. The digital nature of ISDN 2B1Q ensures that voice transmissions remain clear and free from the noise and distortion characteristic of analog systems. Furthermore, the technology provides enhanced error detection and correction mechanisms, contributing to a more robust and dependable communication experience.
In addition to voice and data services, ADTRAN ISDN 2B1Q supports features such as caller ID, call waiting, and call forwarding, further enriching the user experience. Its compatibility with various networking devices and systems allows businesses to integrate ISDN into their existing telecommunication infrastructures without significant changes or upgrades.
In conclusion, ADTRAN ISDN 2B1Q stands out as a reliable and versatile technology that brings digital communication capabilities to traditional telephone lines. With its support for simultaneous voice and data calls, rich feature set, and compatibility with existing systems, it serves as a valuable solution for businesses looking to enhance their communication effectiveness while leveraging their current infrastructure.
