Adtran 4200754L1 Atlas 550 Dual USSI Module - RS-449/V.36 EXpansion Module

Product Description

The Adtran 4200754L1 is a Dual Universal Serial System Interface (USSI) Module designed as an expansion option for the Adtran Atlas 550 access router. This module equips the router with two high-speed serial ports that adhere to the RS-449 and V.36 interface standards. These standards are often associated with synchronous serial communication and are used for Wide Area Network (WAN) connectivity, particularly for leased lines and digital data services. The RS-449 interface is a standard that defines the physical connection and signaling for high-speed serial data transmission, often used in conjunction with V.36, which specifies the functional characteristics of the interface. These interfaces are known for their robustness and ability to support higher data rates over longer distances compared to older serial standards like RS-232. The dual-port configuration allows for flexible network designs, enabling connections to multiple WAN links or serial devices simultaneously. By integrating the 4200754L1 module into an Atlas 550 router, businesses can leverage its capabilities for various serial communication needs. This includes establishing dedicated leased line connections, interfacing with specific telecommunications equipment, or connecting to legacy systems that rely on serial interfaces. The module ensures reliable and high-performance serial data transport, making it a valuable component for organizations requiring specialized WAN connectivity solutions.
