nnnn

The Symmetricom® TimeHub® 5500 is the

nnnn

next generation Building Integrated Timing

nnnn

Supply (BITS) designed for communication

nnnn

service provider networks. TimeHub 5500 is

nnnn

an NGN-ready platform designed to meet

nnnn

all traditional central office synchronization

nnnn

and timing requirements. It provides next

nnnn

generation packet timing solutions critical

nnnn

to advanced service offerings such as IPTV

nnnn

and wireless network backhaul. Already

nnnn

deployed as the workhorse for major fiber

nnnn

networks in North America, the TimeHub

nnnn

5500 is the platform of choice for delivery of

nnnn

carrier-grade NTP and IEEE 1588 Precision

nnnn

Time Protocol (PTP) required to assure high

nnnn

QoS delivery of packet-based applications

nnnn

and content.

nnnn

The TimeHub 5500 System

nnnn

Explosive growth in telecommunications

nnnn

traffic, especially in video and data, has

nnnn

led to new technologies and critical

nnnn

applications. Service providers are growing

nnnn

to meet this demand. As a result, the

nnnn

requirements for synchronization have

nnnn

changed dramatically.

nnnn

Symmetricom's TimeHub 5500 is the next

nnnn

generation BITS. It is a modular, fully

nnnn

redundant timing distribution system that

nnnn

tracks incoming timing references and

nnnn

qualifies the signals against network timing

nnnn

standards. It then filters and distributes

nnnn

precise timing to all equipment in the

nnnn

central office.

nnnn

The TimeHub 5500 main shelf provides

nnnn

up to 160 1+1 protected outputs. If more

nnnn

outputs are required, up to four expansion

nnnn

shelves can be connected to the main shelf,

nnnn

ncreasing the capacity to over 1,4-00 fully

nnnn

protected 1+1 ports per system.

nnnn

The Time Hub 5500 systems offers NTP

nnnn

and PTP packet synchronization with

nnnn

cards in single server or 1:1 protected

nnnn

configurations. Additional server cards

nnnn

grow total client capacity. With these packet

nnnn

network synchronization capabilities, the

nnnn

TimeHub 5500 is a key element in the

nnnn

Symmetricom synchronization distribution

nnnn

architecture (SDA) for LTE networks

nnnn

allowing it to supply PTP sync for the LTE

nnnn

macro and metro base stations as well as

nnnn

carrier-grade NTP sync for residential and

nnnn

enterprise small cells.

nnnn

Management and Alarm Collection

nnnn

The TimeHub 5500 system provides a new

nnnn

dimension in management by integrating

nnnn

and monitoring the performance of legacy

nnnn

equipment.

nnnn

As an intelligent network element

nnnn

TimeHub 5500 provides full visibility and

nnnn

manageability of all input and output ports

nnnn

and all cards on the main and expansion

nnnn

shelves. System parameters can be

nnnn

modified and controlled through any of its

nnnn

multiple interfaces—serial and Ethernet.

nnnn

Symmetricom's TimePictra Element

nnnn

Management System is available to support
