SSU 2000 and SSU 2000E
Generate and distribute superior synchronization signals for advanced network services.
The SSU 2000 and SSU 2000e are intelligent, fully manageable Synchronization Supply Unit or Timing Signal Generator designed to meet the latest and evolving industry standards. These carrier-grade systems support traditional T1/E1 synchronization as well as NTP and IEEE-1588 PTP synchronization in next generation packet networks and 4G/LTE wireless networks.
Overview
The Microsemi ® SSU 2000 and SSU 2000e are fully manageable synchronization systems used by communications network operators to generate and distribute superior synchronization signals for their networks. The SSU 2000 conforms to ANSI standards and is NEBS certified, while the SSU 2000e is ETSI certified. Both systems use the same plug-in cards.
In addition to traditional frequency network timing capabilities for SDH/SONET networks, the SSU 2000/SSU 2000e supports packet network synchronization with carrier-grade Network Time Protocol (NTP) server and IEEE 1588 Precision Time Protocol (PTP) Grandmaster capabilities. The platform supports the seamless introduction of SyncE output capabilities elements into your network through the optical Ethernet port on the PTP grandmaster card. The SSU 2000/SSU 2000e is a key element in the Microsemi Synchronization Distribution Architectures for LTE networks: synchronizing frequency for backhaul networks with SyncE, supplying PTP sync for the 4G/LTE mobile stations, and providing NTP sync for residential small cells.
Integrated Primary Reference Source, Input Flexibility
Intelligent Clock Cards, Superior Holdover Performance
The SSU 2000/SSU 2000e accepts single or dual clocks. Three clock cards are available to meet different international standards and specific holdover requirements; ITU-T Type 1 (ETSI Slave Clock, enhanced quartz oscillator), Type II (Stratum 2E, enhanced rubidium oscillator), and Type III (Stratum 3E, enhanced quartz oscillator).
High Output Capacity, High Availability Architecture
The SSU 2000/SSU 2000e architecture is designed to integrate intelligent, functional cards into a flexible, fully redundant system to satisfy current capacity and sync technology requirements and allow incremental capacity growth and deployment of new capabilities with additional plug-in cards as they are needed.
The SDU 2000/SDU 2000e Synchronization Distribution Unit expansion shelves connect to a corresponding SSU 2000/SSU 2000e main shelf to provide additional output signals. The expansion shelves use the framing and synchronization features of the main shelf to drive an array of output cards. Any combination of T1, E1/2048 kHz, Composite Clock and RS-422 output cards, as well as NTP and PTP server cards, may be installed.
T1 and E1 output cards may be configured in redundant pairs providing twenty 1:1 fully protected outputs per pair. A fully configured SSU 2000 system provides T1/E1 output total capacity of up to 1280 unprotected ports or 640 protected ports. A fully configured SSU 2000e system supports up to 460 protected or unprotected ports.
