nnnn

transactions, PTP clients

nnnn

• Proven interoperability

nnnn

Major Applications

nnnn

• Primary Reference Source (PRS), PRC

nnnn

based on Global Navigational Satellite

nnnn

System (GNSS]

nnnn

The Symmetncom® SSU 2000 and SSU

nnnn

2000e are fully manageable synchronization

nnnn

systems used by communications network

nnnn

operators to generate and distribute

nnnn

superior synchronization signals fortheir

nnnn

networks. The SSU 2000 conforms to ANSI

nnnn

standards and is NEBS certified, while the

nnnn

SSU 2000e is ETSI certified. Both systems

nnnn

use the same plug-in cards.

nnnn

h addition to traditional freguency

nnnn

network timing capabilities forSDH/

nnnn

SONET networks, the SSU 2000/SSU 2000e

nnnn

supports packet network synchronization

nnnn

with carrier-grade Network Time Protocol

nnnn

(NTP) serverand IEEE 1588 Precision

nnnn

Time Protocol (PTP) Grandmaster

nnnn

capabilities. The platform supports the

nnnn

seamless introduction of SyncE output

nnnn

capabilities elements into your network

nnnn

through the optical Ethernet port on the

nnnn

PTP grandmaster card. The SSU 2000

nnnn

and SSU 2000e use the latest hardware

nnnn

and software integration technologies to

nnnn

provide a complete synchronization system

nnnn

for current and future network needs.

nnnn

The SSU 2000/SSU 2000e is a key element

nnnn

in the Symmetricom synchronization

nnnn

distribution architecture (SDA) for LTE

nnnn

networks, synchronizing freguency for

nnnn

backhaul networks with SyncE, supplying

nnnn

PTP sync for the 4G/LTE mobile stations,

nnnn

and providing NTP sync for residential

nnnn

small cells.

nnnn

High Capacity, High

nnnn

Availability Architecture

nnnn

The SSU 2000/SSU 2000e architecture is

nnnn

designed to integrate intelligent, functional

nnnn

cards into a flexible, fully redundant

nnnn

system to satisfy current capacity and

nnnn

synchronization technology reguirements

nnnn

and allow incremental capacity growth

nnnn

and deployment of new capabilities with

nnnn

additional plug-in cards as they are needed.

nnnn

The SDU 2000/SDU 2000e Synchronization

nnnn

Distribution Unit (SDU) expansion shelves

nnnn

connect to a corresponding SSU 2000/

nnnn

SSU 2000e main shelf to provide additional

nnnn

output signals. The expansion shelves use

nnnn

the framing and synchronization features

nnnn

of the main shelf to drive an array of output

nnnn

cards. Any combination of T1, E1/204-8 kHz,

nnnn

Composite Clock and RS-422 output cards,

nnnn

as well as NTP and PTP server cards may

nnnn

be installed.

nnnn

T1 and E1 output cards may be configured

nnnn

in redundant pairs providing 20 1+1

nnnn

fully protected outputs per pair. A fully

nnnn

configured SSU 2000 system provides

nnnn

T1/E1 output total capacity of up to 1280

nnnn

unprotected ports or 64-0 protected ports. A

nnnn

fully configured SSU 2000e system supports

nnnn

up to A6Q protected or unprotected ports.

nnnn

Both shelf systems support high capacity

nnnn

NTP and PTP cards in single server or 1:1

nnnn

protected configurations. Additional server
