Optimux-1551 ( OP-1551 ) STM-1/OC-3 multiplexer from RAD
Optimux-1551 ( OP-1551 ) is an STM-1/OC-3 multiplexer that combines high capacity, operational simplicity, and cost benefits. Up to 21, 42, or 63 E1, or 28, 56, or 84 T1 tributary 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. E1 / T1 over SDH/SONET applications are supported via preset software configurations for operation in multinational environments on the RAD Optimux-1551 ( OP-1551 ).
Optimux-1551 ( OP-1551 ) modules, including fans and power supplies, are hot-swappable, making the RAD Optimux-1551 ( OP-1551 ) fully compatible with carrier class requirements.
RAD Optimux-1551 ( OP-1551 ) Main link 1+1 unidirectional redundancy on the 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.
Optimux-1551 ( OP-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 RAD Optimux-1551 ( OP-1551 ) allow easy installation at customer premises or in telecommunication buildings.
RAD Optimux-1551 ( OP-1551 ) 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, RADís client-server CORBA-based SNMP network management application. NMS is connected via the dedicated Ethernet port
ConfiguRAD, RADís 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.
