Product Description
The HP JG457-61001 is a specialized High-Performance Interface Module (HMIM) designed to expand the Wide Area Network (WAN) capabilities of HP Modular Switch Router (MSR) platforms. This module specifically equips compatible MSR routers with four independent T1 interfaces, allowing for direct connectivity to traditional T1 leased lines. T1 lines are a common standard for digital telecommunications transmission in North America and Japan, offering a data rate of 1.544 Mbps. Beyond supporting full T1 connections, this module is also capable of Fractional T1 operation. This means that each T1 line can be subdivided into smaller, independent channels, typically in 64 Kbps increments. This flexibility allows organizations to provision only the bandwidth they need, optimizing costs for WAN connectivity by avoiding the need for full T1 circuits when lower bandwidth is sufficient. Installation of the JG457-61001 module into an MSR router chassis provides a robust solution for connecting branch offices, remote sites, or dedicated WAN links. It is essential for network designs that require integration with legacy T1 infrastructure or for providing dedicated, high-quality voice and data services over these established circuits. The module's design ensures reliable performance and seamless integration within the MSR ecosystem.
