OSA 5533C SDU Synchronization Distribution Unit OVERVIEW The steady expansion and growth of telecommunication services has resulted in the implementation of complex networks. These often contain a large number of network elements requiring proper synchronization to ensure a smooth network operation with the required quality of service. Further growth results in additional output capacity being required at the network nodes to synchronize the supplementary elements and thus makes it necessary to implement expansion synchronization equipment. To meet this requirement, Oscilloquartz proposes its compact Synchronization OSA 5533C SDU. HIGHLIGHTS Synchronization Distribution Unit with holdover capability Single or dual input Up to 64 outputs Up to 24 E1 or T1 traffic carrying signals Holdover: compliant to ITU-T G.812 SSU (Type III) requirements Full support of SSM on E1/T1 Wide choice of output interfaces: 2.048Mbit/s (E1), 1.544 Mbit/s (T1), 64/8 kbits/s Composite Clock (CC), 2.048/5/10 MHz. Output protection: (1:1) and unprotection modes Wide choice of connectors and impedances Fully locally and remotely manageable Fully maintenance-free operation Oscilloquartz S.A. / Rue des Brévards 16 / CH-2002 Neuchâtel Switzerland / Tel.+41(0)32 722 55 55 / Fax+41(0)32 722 55 56 [email protected] / www.oscilloquartz.com Distribution Unit:

OSA 5533C SDU Synchronization Distribution Unit OVERVIEW OUTPUT AND RE-TIMING The OSA 5533C SDU provides a very economical and reliable solution to the distribution of synchronization references to network elements, such as switches, cross-connects and multiplexers. The OSA 5533C SDU can provide both synchronization distribution and traffic re-timing, avoiding the need for separate equipment (and additional management connections). The OSA 5533C SDU provides up to 48 or 64 outputs referenced to the selected input or to the Holdover Unit. 1:1 card protection is available as an option for all output...

OSA 5533C SDU Synchronization Distribution Unit MANAGEMENT The OSA 5533C SDU is manageable in three different ways: Locally, through the RS-232 port using the OSA Local Manager for 5533C, a graphical, intuitive windows-based application Remotely, through the RS-232 port and a modem/LAN connection, using the same Local Manager coupled with the OSA Remote Access Manager (RAM) software. Remotely, through TCP/IP connection to the network management center, using Oscilloquartz’ renowned synchronization management system- SyncViewTM Plus Functional Diagram www.oscilloquartz.com
