Description
The HP JD556AR is a Network Module for HPE MSR (Modular Switch Router) series routers, featuring four T1 interfaces. This module is specifically designed to provide Wide Area Network (WAN) connectivity using the T1 digital transmission standard. T1 lines are commonly used in North America and parts of Asia for digital voice and data transmission, offering a bandwidth of approximately 1.544 Mbps per line. A key feature of the JD556AR is its support for Inverse Multiplexing over ATM (IMA). IMA is a protocol that allows multiple lower-speed links, such as T1s, to be aggregated together to create a single, higher-bandwidth logical link. This enables organizations to increase their WAN bandwidth cost-effectively by combining several T1 circuits, providing a more robust and flexible connection than a single T1 could offer. This module is hot-swappable, meaning it can be installed or removed from a compatible HPE MSR router chassis without powering down the device. This is crucial for maintaining network uptime and allowing for seamless upgrades or changes to the router's WAN connectivity. The JD556AR enhances the versatility of MSR routers, enabling them to connect to various WAN services and aggregate bandwidth efficiently.
