OSA 5548C TSG

OSA 5548C TSG ,Timing Signal Generator is a scalable synchronisation solution ranging anywhere from 20 unprotected outputs up to a thousand protected outputs by adding up to four expansion shelves to the core unit. Its ultra compact footprint makes it ideal for telecom operators to provide scalable network synchronisation in over-crowded exchanges. The OSA 5548C TSG’s distributed intelligence message passing system eliminates single points of failure and guarantees reliable up time. Core unit and expansion shelves share the same modules, minimising overall administrative complexity and enabling reduced homologation activity.

  • Unique design of master, expansion and remote shelves
  • Intuitive and modular architecture adapted to all telecom node sizes
  • Stratum 1 / ITU-T G.811 PRC with optional dual GPS cards and ITU-T G.812 Type I, II or III SSU holdover
  • GR-2830 Primary Reference Source (PRS)
  • Universal output and input module design

Synchronization Supply Units (SSU) are widely deployed for SDH legacy network synchronization in carrier and enterprise network infrastructure. With the migration to packet-switched network technology and SDH continuing to be used in production networks, the smooth migration from legacy to next-generation network synchronization becomes a critical task.

IEEE 1588v2 Precision Time Protocol (PTP) has been established for precise frequency, phase and time-of day synchronization across packet networks. In addition to deploying stand-alone PTP Grandmaster devices, PTP Grandmaster functionality can be integrated into existing SSU and TSG solutions, leveraging existing infrastructure and enabling smooth migration.

 

Applications: Railways, Communications Network, 4G/LTE, 3G/UMTS

High Capacity IEEE 1588 PTP Module

Synchronization Supply Units (SSU) are widely deployed for SDH legacy network synchronization in carrier and enterprise network infrastructure. With the migration to packet-switched network technology and SDH continuing to be used in production networks, the smooth migration from legacy to next-generation network synchronization becomes a critical task.

IEEE 1588v2 Precision Time Protocol (PTP) has been established for precise frequency, phase and time-of day synchronization across packet networks. In addition to deploying stand-alone PTP Grandmaster devices, PTP Grandmaster functionality can be integrated into existing SSU and TSG solutions, leveraging existing infrastructure and enabling smooth migration.

The High-Capacity Telecom IEEE 1588 PTP Module from Oscilloquartz is designed to deliver precise and reliable synchronization from existing SSU platforms. It supports
a large and market-leading number of PTP slave clients and is compatible with the OSA 5548C SSU/TSG platforms as well as the OSA 5335 modular PTP Grandmaster.

The scalable and modular design allows operators to increase the number of PTP clients as their network grows.

Key Features

  • PTP Grandmaster module for highly accurate synchronization
  • Compliant with ITU-T G.8272 Primary Reference Time Clock
  • Compliant with ITU-T G.8265.1 Telecom Profile for frequency delivery
  • Compliant with ITU-T G.8275.1 Telecom Profile for phase and time delivery
  • Synchronous Ethernet according to ITU-T G.8262 and G.8264
  • High slave capacity with up to 1024 PTP clients per module
  • Support 1:1 card redundancy
  • Scalable system architecture and software licensing

TCC-NTP Server Card

Plug-in NTP server for OSA 5548C SSU/TSG

The availability and distribution of accurate timing information across networks is important for many reasons. Even timing discrepancies as small as a fraction of a second can cause serious errors e.g. where distributed procedures depend on coordinated times to ensure that proper sequences are followed. The availability of precise timing not only helps meet QoS targets and increased customer satisfaction, it also ensures more accurate operations and precise billing systems.

Oscilloquartz’s high performance TCC-NTP (Time Code Card Network Time Protocol) module together with the OSA 5548C SSU delivers a complete NTP solution to any IP-based network. The TCC-NTP Card is a NTP Stratum 1 server which provides a reliable and easy synchronization of Ethernet TCP/IP network. The TCC-NTP card can be installed by just plugging it into in any empty Output card (OUC) group slot of the OSA 5548C SSU/TSG. Up to 10 TCC-NTP cards can be installed in the OSA 5548C SSU-200, making the OSA 5548C as the most redundant and protected NTP server in the market.

Its own base time and algorithm guarantee a high level of accuracy when the GPS card is tracked. Furthermore, the TCC-NTP takes full advantage of the exceptionally high availability and superior holdover performance of the OSA 5548C SSU.

In case of GPS loss, the TCC-NTP references its time base to the best source available: one of the 8 OSA 5548C’s sync inputs or the internal Rubidium or OCXO sources. In these conditions, the time needed to accumulate a time error of 1ms in holdover is more than 4 months when locked on its internal Rubidium and more than 10 days when locked on its internal OCXO.

Each TCC-NTP card provides a high security level: 64 bits RSA™ MD5 encryption, leap time protection, high stability time base and an independent Ethernet port that guarantee security and reliability of its NTP timing service.

The TCC-NTP is easily and safely manageable via the  Oscilloquartz’ SyncViewTMPlus Management Software.
