RAD Enhances Versatility of Optimux-1551 Fiber Mux to Offer Better ROI for Customers Requiring Less Traffic Capacity

RAD Data Communications has introduced an enhanced version of the Optimux-1551 fiber multiplexer, offering two new user tributary modules that support 21 E1 or 28 T1 ports and 42 E1or 56 T1 ports, respectively. This is in addition to the initial tributary module, which serves 63 E1 and 84 T1 channels. Individual channels are mapped into a single channelized STM-1/OC-3 uplink, for extending the local loop up to 80 km (50 miles), while creating a transmission layer fully compatible with regional and national SDH/SONET networks.

“The Optimux-1551 fiber multiplexer is the most reliable STM-1/OC-3 terminal in the market, with a full spectrum of optional redundancies,” explains Orly Nahum, Senior Product Line Manager for TDM Equipment at RAD Data Communications. “By offering the choice of additional tributary channel modules that are better calibrated to user traffic requirements, RAD can improve the ROI per service port for its customer base.”

E1/T1 over SDH/SONET applications are supported via preset software configurations for operation in multinational environments. Uplink and tributary modules, including fans and power supplies, are hot-swappable, making the Optimux-1551 fiber multiplexer fully compatible with carrier class requirements with no single point of failure.

Main link 1+1 unidirectional redundancy is supported in compliance with the G.841 and GR-253-CORE standards. Tributary channel 1+1 protection is provided through an optional redundant module.

The Optimux-1551 is available with a choice of either standard coaxial or fiber optic short/long-haul aggregate main link interfaces. Three dual-purpose multiplexer cards – 21 E1/28 T1, 42 E1/56 T1, and 63 E1/84 T1 tributary channels – support transparent data transfer in compliance with the G.703 recommendation. The TDM traffic is mapped into SDH or SONET containers, while retaining full use of the 155 Mbps capacity.

Compact size and low power consumption of Optimux-1551 allow easy installation at customer premises or in telecommunication buildings.

Setup, control, status monitoring, and diagnostics information can be performed using one of the following methods:

* ASCII terminal connected to the DB-9 control port

* Telnet host via the dedicated Ethernet port

* Network management station (NMS) running RADview-EMS, RAD’s client-server CORBA-based SNMP network management application. NMS is connected via the dedicated Ethernet port

* ConfiguRAD, RAD’s Web-based remote access terminal application, via the dedicated Ethernet port.

* TFTP for software update and remote configuration, via the dedicated Ethernet port

The unit provides high-quality performance monitoring of the traffic path, from the SDH/SONET network to the customer premises, thereby assuring high availability.
