The Cisco Interface Module NM-4B-S/T= is a four-port ISDN-BRI (Basic Rate Interface) network module designed to support digital modem functionality. This module is specifically engineered for use with Cisco systems and delivers reliable ISDN connectivity across multiple network devices. It provides distinct enhancements that cater to networks requiring basic ISDN services, such as small to medium businesses or offices with remote connectivity needs. Each port on this interface module supports independent operation, allowing for flexible deployment across various environments.
With four ISDN BRI (S/T interface) ports, the NM-4B-S/T= offers efficient and high-speed digital communication. This is especially beneficial when connecting to ISDN-based services, further enhancing network flexibility and reliability. The interface ensures users have access to fast data transfer rates, which are essential for applications like voice, video, and data. The device supports essential ISDN features such as call setup, teardown, and general call maintenance.
The NM-4B-S/T= features four separate BRI ports, each equipped to offer bandwidth up to 128 Kbps, combining two 64 Kbps B channels for data transfer alongside a separate D channel for signalling purposes. Each channel operates independently, optimising the performance of data-heavy applications. The ports provide excellent compatibility with Cisco systems, ensuring smooth integration into existing Cisco-based networks. The module format also allows for easy installation into modular routers such as the Cisco 2600 Series and the Cisco 3600 Series routers, making it a versatile option for expanding ISDN capabilities.
This module stands out for its capability to enable point-to-point and point-to-multipoint connections, allowing businesses greater control over their network configurations. Designed to meet the needs of modern network systems, the NM-4B-S/T= adds valuable ISDN support functionality in a robust, compact form factor, ensuring reliable service and ease of maintenance.
