The TimeSource 2700 is a Primary Reference Source (PRS) that tracks and ensembles multiple CDMA pilot signals. The CDMA pilot signals originate from CDMA base stations equipped with GPS based timing sources traceable to UTC. A pilot channel is transmitted continuously by each CDMA base station. Pilot channels allow the handset to acquire timing, provide phase data for demodulation, and provide a signal strength comparison between base stations. The TimeSource 2700 provides Stratum 1 outputs by using advanced BesTime technology. By using inputs from one to eight CDMA pilots and a rubidium local oscillator, the TimeSource 2700 meets Telecondia GR2830 network performance requirements. If the CDMA signals are disrupted, the BesTime algorithm continues to predict CDMA timing information, which enhances system holdover performance. Since CDMA is one of the most widely-used digital wireless services in the United States, the TimeSource 2700 can be installed in most metropolitan areas. Because the antenna is located inside the building within a few feet of the shelf, the antenna installation problems sometimes encountered with GPS based systems are eliminated.
The TimeSource 3000 is a Primary Reference Source (PRS) that receives and processes signals from GPS satellites, and outputs Stratum 1 synchronization signals traceable to UTC. TimeSource 3000 applications include synchronization for central offices, radio base stations, transmission nodes, and other instances where a primary reference source can improve the performance of telephony network facilities. The TimeSource 3000 creates timing outputs by ensembling signals from several sources. The sources include GPS signals, an onboard local oscillator, and optional T1 and remote oscillator signals. Timing outputs created from the ensemble are composed of the most stable and least noisy parts of each input. Synchronization outputs are delivered in a framed, all-ones, T1 format, a 10 MHz signal, a 1 pps signal, composite clock signals (optional), and time of day (TOD) signals. The TimeSource 3000 minimizes timing impairments, such as jitter and wander, that are created by network and transmission systems. The synchronization timing is traceable to the GPS, which provides the highest level of synchronization for telephony networks. The TimeSource 3000 with its GPS input is a standalone office PRS. With the optional inputs ensembled, overall system performance is improved, and holdover is extended if GPS signals become disrupted.
Been working with PICS Telecom for years. Wonderful company and Bill McAuliffe is a great rep to work with!
I think Bill McAuliffe is the best. Always helpful and has gotten me out of a lot of jams.
I work with Bill McAuliffe and a lot of times we are buying switches but often we have off the wall or weird equipment that we have to find and Bill often times goes above and beyond. He may not always be able to get us the best price, but we definitely come back for the Service and effort.
I have worked with PICS Telecom for years and it has been a wonderful experience. Every one is very supportive and provides excellent customer service. Bill McAuliffe always goes above and beyond to address our needs and locate (or in some cases, build) difficult-to-find equipment.
Worked with Bill McAuliffe finding some much needed, hard to find parts. He hooked me up and was a pleasure to deal with. Will definitely buy from again!
Found Pics Telecom during a online search for secondary market equipment. Had a conversation with Bill and he helped me find the equipment I was looking for and gave me a great price! I have completed 2 other transactions with him since then. This is a wonderful company to work with, Thanks Bill for all of your help, you have been awesome to work with and I look forward to working with you on future equipment needs.
We have worked with Bill several times on several projects and Bill has never let us down. He is always quick to respond to our questions and can acquire specific gear we are looking for within a very short period of time.
Bill is always very helpful on getting the equipment we need. He is fast in response time and always competitive pricing. If there is any issues with the equipment after receiving it he has replaced it with no questions. In short a good person / company to deal with.
I appreciate the quick response and shipping. I try to check with you any chance I get when I need to purchase Ciena gear. You have great pricing and I have not received a defective unit yet so I know that I will get a quality part when I purchase thru you.
Thank you and it’s been a pleasure working with you and your team! I look forward to doing more business with you in the future!
I have been pretty fortunate lately in regards to equipment failures and replacements, but PICS has always been (thanks to the quality of service I’ve received from you) at the top of my list when I do have a need.
