Architecture & OptionsBased around a 19-inch 3U high standard rackmount chassis, theWorldNet Oslo is modular in design and built to customer requirements.Users can choose from a variety of “hot swappable” modules to fit theirparticular audio, voice, data and transport needs.The modular design together with inherent and optional failsafemechanisms ensure that the WorldNet Oslo provides the ability todeliver audio under extreme circumstances.As the unit is designed around a mid-plane architecture, each moduleis supplied as a pair with a front panel indicator plug-in card and acorresponding interface module.Audio / Aux Data / Voice / Video Transport ModulesSecondaryTransportModulePrimaryTransportModuleMCU /SystemControllerRedundantAC/DCPowerSuppliesMaster Controller (MCU) ModuleThe MCU module is responsible for the configuration and monitoring of the complete WorldNet Oslo system.• System Control - The MCU module controls the operation of all other modules in the system,allocating them time slots on the backplane and sending configuration information.• Status Monitoring - The processor constantly polls the status of individual transport modules andmakes failsafe decisions based on this status. The module also monitors the frame temperature andthe power supplies of the system.• Hardware Alarms - The alarm port on the MCU module provides seven GPIO relay contact closures inorder to indicate critical status and alarm conditions.• Hot-Swappable - Once a WorldNet Oslo is configured, it is able to continue to operate in the event of an MCU card failure as each cardwill hold its local settings. The MCU can then be “hot swapped” and will recover the current system settings from the individual modules• In-band Management - The IP interface on the MCU module is the communication interface for the CMS (Codec Management System)software. It also provides the ability to control multiple remote WorldNet Oslo frames throughout a network using in-band management.T1/E1 Transport ModuleThe T1/E1 module is one of the mostcommon choices for audio transportdue to the reliability and widespreadavailability of T1 and E1 circuits. Thereare two physical slots to accommodatetransport modules on the WorldNet Oslo:one for the main circuit and a second forbackup, bridging or crossover of up tofour lines. The E1 module is available with both RJ45 andBNC connectors.• Line Redundancy - Each module comprises two T1/E1 framerdevices and two line interfaces enabling line redundancy.• Drop & Insert - The T1/E1 module provides a failsafe circuit that,in the event of total failure of the module, connects the upstreamT1/E1 circuit to the downstream T1/E1 circuit, thereby preservingthe integrity of the data path to any other devices on the networkring• Hot Standby Module Backup - The T1/E1 module also provides anintercard high speed connection to indicate its health conditionto the second stand-by multiplexer (if fitted). In the event of badstatus, the backup module takes over the whole payload from theactive device, minimizing disruption.• Contribution Data & Clocking - Any data received by the X.21 portis then placed onto the T1/E1 transport link. In combination withthe external clock input, this module provides versatile systemtiming options to connect to almost any network.13IP Transport ModuleThe IP interface module is the other mainalternative for audio and data transport.Again, two cards can be fitted, one for themain circuit and a second for backup ora second link.• Powerful Processing - offers apowerful high performance NetworkProcessing Engine capable of supporting many complex IP routinginfrastructures.• Multiple Streams to Multiple Destinations - Up to 24 real-timeaudio streams to 24 individual destinations can be set up on theIP module’s streaming table. The unit can be configured for pointto-point,multiple unicast and multicast applications.• Low, Stable Latency - An on-board VCXO on all audio modulesenables clock synchronization and stable data flow across IPlinks. Alternatively, the IP module can be connected to an externalAES/EBU or GPS reference clock to ensure synchronized deliverywithout introducing delay.• Quality of Service - The module supports QoS settings to ensureoptimum audio performance over packetized networks.• IP Backup - The system offers automatic backup using eitherthe second IP port of the IP interface module or a redundant IPinterface module.• Bridging IP Networks and T1/E1 lines - The WorldNet Osloenable progressive migration from synchronous to asynchronousnetworks including bridging content across both worlds.
