Solutions to Design, Deploy & Manage Enterprise IP Phones
Low power, easy-to use ICs and systems for power and timing distribution in enterprise IP phone networks. Microsemi’s IC portfolio enables efficient and quick design of enterprise IP phones, while our industry-leading PoE midspans and NTP servers facilitate power and timing distribution in enterprise networks.
Designing IP Phones: PoE ICs, Diode Bridges and Voice Processors
Microsemi has a broad portfolio of ICs for both Desktop IP phones and speakerphones, including:
- Power over Ethernet (PoE) PDs
- Echo cancellation hardware and software
- Ethernet PHYs
- Switching regulators
- Linear regulators
- TVS diodes
- Diode bridges
The echo cancellation hardware platform and firmware pack include and advanced acoustic echo canceller and noise reduction for speakerphones and conference units. The PoD PDs can be used to receive from 3.84W (for class 1 phones) all the way to 95W for fully capable IP phones used to forward power to thin/zero clients. Microsemi's switching regulators with constant frequency hysteretic control lead the industry in space, energy efficiency and transient response.
Enabled HD Voice in IP Phones: High Performance Audio Processor
Designed for IP phones, security system, and many other hands-free applications, Microsemi’s new Timberwolf™ audio processor (ZL38040) features the company’s innovative AcuEdge™ acoustic technology, which is a set of highly-complex and integrated algorithms that allow the user to extract intelligible information from the audio environment from which they are communicating. The license-free, royalty-free audio solutions along with Microsemi’s highly-integrated hardware accelerators enable the development of world-class HD Voice features for IP phone and conference phone applications. The comprehensive Microsemi AcuEdge™ package accelerates customers’ time-to-market via a validated reference design and easy-to-use development tools including the MiTuner™ automated AEC tuning kit. Furthermore Microsemi’s audio processors have been field tested in tier-one OEMs design to meet TIA, ETSI and ITU standards, as well as achieving design-in success in targeted enterprise markets.

Deploying IP Phones: PoE Midspans and NTP Servers
Microsemi's PoE Midspan Injectors can be used to Power IP Phones over Ethernet, removing the need to replace existing switches with PoE-enable switches. Microsemi offers managed, unmanaged, indoor and outdoor PoE Midspans, with 1 to 24 ports, and supplying up to 95W per Ethernet port.
Microsemi's Network Time Servers / NTP Servers are crucial for IP Phone deployment within an enterprise, as they ensure the IP PBX and IP Phones have the same time of the day, with accuracy of +-1.5ms.
Network Time Solutions for IP Phone Deployment
Microsemi's Network Time Servers / NTP Servers are crucial for IP Phone deployment within an enterprise, as they ensure the IP PBX and IP Phones have the same time of the day, with accuracy of +-1.5ms. The latest design features of the Microsemi SyncServer family include "any signal, any connector" flexibility, scalability and security-hardening, high availability and throughput of four independent 10/100Base-T Ethernet ports with IPv6 support, and an easy-to-use intuitive Web interface with various set-up wizards, all essential to support a next-generation network. Deriving time directly from the atomic clocks aboard the GPS satellite system, Microsemi NTP servers deliver the accurate, precision time needed for seamless operation of your IP phone network.

Power over Ethernet (PoE) Systems to Maximize VoIP Investments
IP convergence is often hindered by the high barriers to entry for deploying a VoIP network; replacement costs for the Ethernet switch and manpower costs associated with configuring a switch.
Microsemi's PoE midspans maximize your manpower investment with plug-and-play installation alongside an existing Ethernet Switch. Midspans also eliminate service contract expense with 16 year limited -lifetime warranty on most models.
Additional savings are realized with device scheduling functionality brought by PowerView Pro web-based power management tool, which allows you to automatically schedule devices off during periods of non-use which can cut power expense nearly in half, depending on your locations hours of operation.
PoE-based telephony devices experience increased reliability by connecting directly into an Uninterruptible Power Supply (UPS) and through PowerView Pro's device prioritization feature; which maximizes run-time of critical devices in case of external AC power failure.
