Product SummaryRAD’s Optimux-1551 SDH/SONET terminal multiplexer and Optimux-1553 SDH/SONET terminal multiplexer extend services point-to-point over coax or fiber up to 80 kilometers (50 miles) to remote locations.
The Optimux-1551 SDH/SONET terminal multiplexer combines up to 63 E1 or 84 T1 tributary channels into a single STM-1/OC-3 link, while the Optimux-1553 SDH/SONET terminal multiplexer combines three E3 or T3 tributary channels into a single STM-1/OC-3 uplink
NEBS-3 certified, the Optimux-1551 SDH/SONET terminal multiplexer and Optimux-1553 SDH/SONET terminal multiplexer provide an extremely reliable platform that maximizes uptime for any mission-critical application. Benefits• Cuts leased circuit costs and saves on costly ports on the SDH/SONET ADM by consolidating traffic at the edge of the network • High capacity at a low cost • Plug-and-play installation and operation reduces the need for advanced technical training and saves on installation and support time • Eliminates cost, rack space and management complexity by integrating multiple user ports into a compact platform • Carrier-class redundancy improves network quality of service and protects critical network traffic at all times
Further Product InformationThe Optimux-1551 SDH/SONET terminal multiplexer and the Optimux-1553 SDH/SONET terminal multiplexer deliver traditional PDH services over existing SDH or SONET networks. The products offer the high capacity associated with SDH or SONET add/drop multiplexers (ADMs) with the simplicity and low cost of a terminal multiplexer, significantly reducing operating and capital expenses. High capacity in a compact unitThe 2U-high Optimux-1551 provides connectivity for up to 63 E1 or 84 T1 lines. The 1U-high Optimux-1553 provides connectivity for three E3 or three T3 lines. The products comply with all SDH/SONET standards, and interfaces with existing SDH or SONET backbones through a single or redundant STM-1, OC-3 or STS-3. The Optimux-1551 can be ordered with 21 x E1 or 28 x T1 lines, 42 x E1 or 56 x T1 lines or 63 x E1 or 84 x T1 lines. Carrier-class designDesigned for the rigorous requirements of carriers and service providers, the Optimux-1551 and Optimux-1553 SDH/SONET terminal multiplexers offer a high level of reliability and manageability. Hardware redundancy is designed into the system without the need for custom Y-cables or external devices. This 1+1 redundancy is provided for all user interfaces through an optional second, hot-swappable multiplexer card. 1+1 redundancy is also available for the STM-1/OC-3 main link (unidirectional APS/MSP) and power supply modules. This reliable platform maximizes uptime for mission-critical applications. A fully equipped Optimux-1551 fits in a single 2U 19" shelf, while the Optimux-1553 occupies a 1U shelf. Higher revenues at lower costThe Optimux-1551 and Optimux-1553 SDH/SONET terminal multiplexers allow service providers to extend their network to remote customers, thereby enlarging their customer reach and increasing revenues, without the expenses associated with deploying high-end ADMs, which add unnecessary cost and complexity in “point to network” connections. Compared to the alternative of deploying PDH multiplexers at customer sites, the Optimux-1551 and Optimux-1553 devices interface directly with the existing SDH/SONET TDM infrastructure and consolidates traffic at the edge of the network. This enables service providers to save the cost of fiber deployment and of multiple ports on the ADM. Plug-and-play operationEasy to install, maintain and operate, the Optimux-1551 and Optimux-1553 require no training or expertise. Completely plug-and-play units, the products allow carriers to extend the benefits of SDH/SONET networks to the customer premises or central office in a quick and inexpensive manner. Extend SDH/SONET access up to 80 kilometers (50 miles)Optimux-1551 SDH/SONET terminal multiplexer and Optimux-1553 SDH/SONET terminal multiplexer are especially suitable for extending SDH/SONET network services to remote and suburban locations such as industrial areas and business parks. They are the ideal choice for delivering multiple E1/T1 services. The products can be deployed in point-to-point applications (Figure 1), connecting two sites over fiber, to distances of up to 80 kilometers (50 miles).
In Figure 2, a service provider uses Optimux-1551 to deliver E1/T1 services and Internet access to multiple customers, and uses Optimux-1553 to provide E3/T3 lines to large enterprises with higher bandwidth requirements. |
