OSA 5548C TSG TSG for SONET, SDH and Mobile Synchronization TSG: Timing Signal Generator OVERVIEW The OSA 5548C Timing Signal Generator (TSG) is designed to provide telecom operators with reliable synchronization, using the latest in hardware and software technologies. The OSA 5548C system provides a scalable synchronization solution ranging from 20 unprotected up to thousands of 1:1 protected outputs. The OSA 5548C TSG can be a Stratum 1 redundant source if you decide to include one of two possible GPS cards (this does not change the number of inputs or outputs available). In addition to DS1 and Composite Clock (CC) output cards, any of the 10 main output slots can be equipped with time distribution modules (NTP or PTP) or with DS1 retiming cards. With its complete and consistent family (3U: 60 outputs, 6U:200 outputs, expansions, remote), the OSA 5548C is the TSG of choice when you need scalability and reduced spare parts inventory. This flexibility makes the OSA 5548C the most versatile TSG in the marketplace. HIGHLIGHTS Unique design for Master, Expansion and Remote shelves Intuitive and modular architecture adapted to all control office sizes to 60 protected (1:1) outputs with 3U shelf Up and up to 200 protected (1:1) outputs with 6U shelf Expandable Systems to provide up to 1000 protected outputs Stratum 1 PRS with optional GPS card(s) Choice of Stratum 2 or Stratum 3E holdovers Universal input & output Card design SSM on complete system (Master, Expansion, Remote) TL1 manageable with Local and Remote intuitive Graphical User Interface MAIN APPLICATIONS SDH/SONET Synchronization GPS or Cesium-based PRC System Synchronization Supply Unit (SSU) GPS-based time distribution system Mobile network synchronization PRC for Mobile Switching Centers (MSC) GPS-based time distribution system Next Generation Networks synchronization Time-of Day Server (e.g. NTP, PTP, etc) Timing sources for Sync-E, Ethernet Network Equipment (EEC) Optional NTP and PTP modules 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 Page 1

OSA 5548C TSG TSG for SONET, SDH and Mobile Synchronization High Output Density Tracking and Holdover Each module is only 4 inches tall, contributing to a higher overall port/volume ratio, and therefore reducing the size of the 5548C 6U shelf design to accommodate overcrowded Telecom Hub Rooms and Switching Center rack spaces. This card forms the beating heart of the OSA 5548C TSG. The input reference jitter and wander are filtered by a high quality oscillator with DDS technology. Two types of oscillator are available: High Availability Double Oven Quartz (OCXO) All cards are intelligent and...

OSA 5548C TSG TSG for SONET, SDH and Mobile Synchronization Management Time Code Card (TCC) The management card provides connectivity with local and remote synchronization management systems via a TL1 interface over RS-232 (local) and TCP/IP (remote). OSA Local Manager and SyncView Next Generation Management software provide, locally and remotely, powerful fault, configuration, accounting/inventory, performance and security management functions through an intuitive graphical user interface. Local alarm information is provided as: Time Code allows precise time distribution (when GPS card is installed)....
