Programs that save you time and money

Expert maintenance programs from Microsemi keep your equipment up and running and your network operating at peak efficiency.
Contract-based maintenance programs from Microsemi provide a cost effective way to extend your expertise, increase your operating efficiency, and keep your vital telecom network equipment up and running. Services include round the clock technical support, hardware and software maintenance, spares support, and disaster recovery units that can go operational immediately in case of a service outage.

Global Technical Support

Our Technical Support staff is available globally, 24 hours a day, 7 days a week, 365 days a year. Support is available for all Microsemi hardware, embedded software, firmware, Craft software and Network Management System (NMS) software. For your convenience, support is available on an hourly or annual contract basis. When you have a question, we are just a call or email away. Expert support personnel, including subject matter experts and design engineers can answer your technical questions, troubleshoot problems and resolve any issues quickly and efficiently.

Expert On-Site Maintenance

Available on a contract, or callout-basis, On-Site Maintenance service brings our technical support directly to you. If your Microsemi equipment problems can’t be resolved via telephone, one of our technical experts will travel to your location. We evaluate the equipment on-site, troubleshoot the problem, and make any necessary repairs using field-replaceable plug-ins or spares to resolve an equipment problem (spare parts are supplied by the customer or Microsemi’s Express Loaner Service). On-Site Maintenance services are available on an annual contract basis with guaranteed response times or on a case-by case basis as needed.

Extended Warranty

Extended Warranty contracts extend the initial return-to-factory repair warranty services for Microsemi hardware products. By providing you with a contract return authorization number you avoid the time and expense necessary in requesting, purchasing and processing payments for individual repairs. We guarantee certified factory repair and an update to the latest revision level (when appropriate). An Extended Warranty contract includes guaranteed repair turnaround time so you get the service you need as quickly as possible.

Spares Support

We build Microsemi products to be durable. However, when a unit fails, you want it replaced as quickly and with as little effort on your part as possible. With a Spares Support contract a single phone call is all it takes to obtain advance replacements for any failed units, without the need for time consuming purchase orders to obtain replacement spares or schedule repairs. Call us and we send a Microsemi replacement unit to your location, along with a pre-paid return waybill and packaging for the failed unit. You keep the spare and return the failed unit to our regional warehouse.

Network Time Server Express Loaner Service

Ensure maximum uptime for your enterprise. In the event your time server fails our Express Loaner Service ships a loaner network time server overnight to your location. Simply place a call to Microsemi Global Services and tell us the model of your Microsemi time server. We ship that model overnight to your specified location anywhere in the United States or Canada.

Software Maintenance

Trouble-shooting and problem resolution is just the beginning of the Software Maintenance services we offer. Software Maintenance contracts provide an outsourced solution to supporting the operation and maintenance of your sync network. We offer 24x7x365 global technical support for installation, operation and maintenance of Microsemi software. We perform on-site installation of new releases. Our staff can remotely monitor the health of your network, and dispatch maintenance personnel to resolve alarms as required. During the contract period, we keep your software up to date and operational with patches, point releases, maintenance releases, and related documentation for your purchased version.

Direct Cesium Tube Replacement

Direct Cesium Tube Replacements renew your cesium tube life span and restore performance for far less than the cost of purchasing a new unit. Factory installed and guaranteed replacements are available for many models of cesium instruments manufactured by Microsemi, Agilent® and FEI®. Both standard performance and high performance cesium tubes are available.

Calibration Services

Microsemi calibration service for selected cesium, rubidium and quartz instruments helps ensure your unit’s accurate performance in critical, high reliability timing applications. Cesium units undergo a Frequency Accuracy Stability measurement in our factory, and are calibrated to published specifications from the United States Naval Observatory (USNO). Rubidium and quartz units are calibrated to our factory standard specifications. We also conduct a physical evaluation of each product, so if your unit needs any repairs, we’ll let you know.

All-Inclusive Statement Of Work

Before we deliver any maintenance service, we clarify your requirements and gather information. A comprehensive, all-inclusive statement of work specifies the scope of work, identifies key issues upfront, and delivers a rock-solid quote, so there are no expensive surprises once work begins. The quality of our work ensures your equipment is installed right the first time, on time, and on budget.


Customers may request and purchase repairs on a case-by- case basis. We offer return-to-factory repairs for most current and discontinued products. To request repair work, simply submit a “Request a Repair” form or call one of our call center locations
