Symmetricom Invited to Participate at INSIGHT 100 Fall Conference.

Chuck Perry Will Present, "Evolution of Network Synchronization Requirements, from TDM to IP" on Sunday, October 1, 2006 at "Members-Only" Nortel Conference - Indianapolis, IN

SAN JOSE, Calif. & INDIANAPOLIS -- Symmetricom, Inc. (NASDAQ: SYMM), a worldwide leader in precise time and frequency products and services, today announced systems sales engineer, Chuck Perry, will present, "Evolution of Network Synchronization Requirements, From TDM to IP" on Sunday, October 1, 2006 at 4:00 p.m. at the INSIGHT 100 (inc) Fall Conference in Indianapolis, Indiana. The company is also exhibiting its next-generation time and frequency solutions at the "invitation-only" conference, Monday, October 2, 2006 - Wednesday, October 4, 2006. INSIGHT 100 (inc) is a "members only" forum that requires members to have an installed, operational Nortel SL-100/CS2100.

WHO: Symmetricom Systems Sales Engineer, Chuck Perry

WHAT: Presenting: "Evolution of Network Synchronization Requirements, From TDM to IP" at INSIGHT 100 (inc) Fall Conference

WHEN: Sunday, October 1, 2006 at 4:00 p.m.

WHERE: Omni Severin Hotel, 40 West Jackson Place, Indianapolis, IN 46225

Perry will discuss the evolution and changes with precise time and synchronization as the core network shifts from TDM circuit-switched technology to the more cost-effective IP packet-based technology. Ensuring precise time takes on a whole new meaning within the packet-based environment when delivering new broadband services. He will address the many new issues and considerations of precise time and synchronization for Next Generation Networks.

Hosted by Indiana University and Purdue University, the conference agenda will help attendees "Restart Your Engines" with workshops designed specifically for the technicians/technologists or the architect/planners as well as common workshops intended to enhance understanding and communication between both groups. Equally important, the conference provides an opportunity to meet colleagues from INSIGHT 100 (inc) and Nortel in person - renewing or making new friendships, putting faces to voices from the conference calls and learning as much from networking as from the sessions.

Symmetricom is featuring its SSU 2000 Intelligent NEBS-Compliant Synchronization Supply Unit; TimeProvider[TM] Network Access Synchronization System; and TimeSource[TM] 3000 Primary Reference Source (PRS).

Symmetricom Featured Products

The SSU-2000 is an intelligent, fully manageable Synchronization Supply Unit or Timing Signal Generator. Designed in a NEBS-compliant package, it utilizes the latest hardware and software integration technologies. The SSU-2000 is used for telecom network operators to generate and distribute superior synchronization signals for advanced network services. It is designed to meet the latest and evolving industry standards, including ANSI, Telcordia and CE/CA.

TimeProvider[TM] 3.0 is the latest version of Symmetricom's innovative network access synchronization system that includes NTP server/client with MD5 authentication, RS-422 output signals supporting 1.544 and 2.048 MHz frequencies and an integrated IMC/TPIU card that saves valuable rack space. TimeProvider's innovative architecture combines the tasks of tracking incoming timing references, qualifying signals, filtering and distributing precise synchronization onto a single universal Input, Output and Clock card (IOC).

The stand alone TimeSource 3000 system can be configured as a PRS to front-end and office BITS or as a standalone PRS with 10 outputs for remote or small offices, ideal for public network service providers. TimeSource 3000 offers 1) undisturbed Stratum 1 synchronization when locked to GPS, 2) continued Stratum 1 performance without GPS for up to 72 hours, with optional inputs and 3) the patented multiple input frequency locked loop BesTime[TM] clock engine to produce precise timing outputs.
