LoopStar® 745 and LoopStar® 745P

Cost-Effective Ethernet Over DS3 Solutions With Carrier-Class Management Capabilities

Deliver Management and Service Intelligence to the Remote Customer Edge

Using the LoopStar 745 and LoopStar 745P in conjunction with the LoopStar 700 or LoopStar 722 delivers the greatest value to the customer, as the intelligent services and capabilities of the LoopStar 700 management suite can be fully leveraged at the customer demarcation point via a hub-and-spoke configuration. With a single LoopStar 722 or LoopStar 750 serving as the hub, up to nine LoopStar 745 and LoopStar 745P units can be deployed across a metropolitan area, an office park or up the risers in a multi-tenant building to deliver managed Ethernet services.

In this configuration, each of the LoopStar units can be managed in-band via a management VLAN or out-of-band via Ethernet. The management suite’s remote management capability allows carriers to extend IP management visibility all the way to the remote customer edge. From a single operator viewpoint, a full range of performance statistics, loopback diagnostics, cable integrity testing, and differentiated service definition allows the carrier to remotely manage and provision each individual LoopStar 745 and LoopStar 745P without ever having to touch the unit itself. Customers can be managed remotely and new services can be turned up quickly and easily without any truck rolls, providing huge operational savings.

The LoopStar 745 and LoopStar 745P also offer two hands-off cable tests—one for the DS3 uplink and one for the customer’s Ethernet connection using a built-in Time Domain Reflectometer (TDR).

745, 745P specifications

The ADC 745 and 745P are advanced analog-to-digital converters that serve as integral components in various electronic applications. They are designed to provide high-resolution digital outputs from analog input signals, making them crucial for systems requiring precise measurement and data processing.

One of the primary features of the ADC 745 is its high conversion speed. With a sampling rate of up to 1 megasample per second (MSPS), it can handle rapidly changing signals with ease. This makes it particularly suitable for applications in data acquisition systems, instrumentation, and communication devices. The 745P variant further enhances the original model with improved performance specifications and additional features.

The key technology behind the ADC 745 series is the successive approximation register (SAR) architecture. This technology allows for high accuracy and low power consumption, making the ADC ideal for battery-operated devices. The SAR method uses a binary search algorithm to convert the analog input into a digital output efficiently, resulting in fast and reliable conversions.

One of the standout characteristics of the ADC 745 is its resolution of 12 bits, which ensures fine granularity in measurements. This level of precision is crucial for applications where small changes in signal values need to be detected. The device also boasts an impressive signal-to-noise ratio (SNR), which contributes to its ability to produce clear and accurate digital representations of analog signals.

Another important feature is the built-in reference voltage capabilities, allowing the ADC to be configured for various range settings. This flexibility is essential for adapting to different signal levels, catering to a wide array of applications. Additionally, the ADC 745 series includes features such as an internal sample-and-hold function, which stabilizes the input signal during the conversion process, ensuring that noise and fluctuations do not adversely affect the output.

The ADC 745 and 745P are designed with compatibility in mind, often integrating seamlessly with various microcontrollers and digital signal processors. This compatibility simplifies the design process for engineers and developers, enabling them to incorporate these ADCs into their systems with minimal effort.

Overall, the ADC 745 and 745P represent cutting-edge solutions for analog-to-digital conversion, combining speed, precision, and versatility to meet the demands of modern electronic applications. Their robust feature set makes them a trusted choice for engineers focused on ensuring high-quality data acquisition and processing.
