Solve Today’s Challenging Content Transport Requirements Radio engineers face the challenges of managing their broadcast program contribution and distribution and providing the highest degree of on-air reliability, while still controlling their costs. The field-proven Intraplex® AudioLink PLUS™ E1 audio multiplexing system combines bidirectional transport of program audio with a wide variety of other traffic — including LAN/WAN data, telephone, intercom, fax, and remote control data — all over the same link. And the unique transmission robustness and error mitigation features of Intraplex provide users with unmatched reliability. Get a Complete Range of Audio Options — and More The AudioLink PLUS system offers the industry’s widest range of plug-in modules for program audio, voice and data to combine virtually any mix of payload traffic for transport over E1. Program audio options include true uncompressed linear audio for the highest-quality sound and the lowest processing delay. Compressed audio options such as MPEG II, MPEG III, J.41 and Enhanced apt-X® allow you to increase bandwidth efficiency for consolidation of multiple audio channels and other payloads on the same link. Data modules provide one-way or full-duplex data circuits, with a variety of data rates and formats for LAN/WAN, control circuits, program associated data and legacy devices. Voice modules transport voice-grade audio for telephone, inter-com and fax applications. Whether over E1 land lines or microwave radios, the AudioLink PLUS system delivers superior audio quality and efficiency to broadcast stations and networks worldwide. E1 and IP — Built for the Future Intraplex AudioLink PLUS E1 multiplexers can be used in conjunction with Intraplex NetXpress™ IP multiplexers. Together, they allow gradual migration from E1 to IP and enable the deployment of hybrid E1/IP contribution and distribution networks that share a common family of audio interface modules.

The Intraplex® CrossConnect system and CrossConnect server provide routing and switching capabilities for up to six T1 or E1 circuits, as well as automatic backup switching for STL links. The CrossConnect Server also accepts a wide variety of plug-in modules for integrated drop and insert of voice, data and program audio. Station operators can dynamically route services among multiple studio and transmitter locations, sharing programming and administrative resources among geographically separated facilities. CrossConnect Servers reduce transport link requirements, providing cost savings in both point-to-point and point-to-multi-point networks. Broadcasters can mix and match program audio, voice and data feeds among multiple studio and transmitter locations and save on programming, talent and administrative costs by sharing transmission resources among stations. Intraplex CrossConnect Systems and Servers can help ensure the most efficient use of the available transmission capacity and reduce costs. CrossConnect Systems and Servers give users complete flexibility to combine, interconnect, and multicast traffic among up to six T1 or E1 lines.

The next generation of digital STL Our challenge: to design a studio-to-transmitter link (STL) for your most demanding 950 MHz applications — one as reliable and robust as Intraplex® T1 and IP audio links. Digital STL manages much more than audio, so installation and configuration need to be straightforward, not a science project. Data should not be optional, requiring additional boxes and complexity. Your STL should be ready, out of the box, for AM, FM and HD Radio™, as well as future multimedia applications. Earlier digital STLs were not designed for IP data transport. Adding IP data to them required optional modules and external add-ons, and many engineers working on HD Radio installations reported spending much time and money trying to eliminate glitches. Our solution: HD Link™ is designed to manage all HD Radio™ transport scenarios, regardless of where you place your importer and exporter. Its two prioritized Ethernet paths give preference to HD Radio™ data over control and other LAN/WAN data. It supports both UDP and TCP, and even handles the switching of TCP return packets over asymmetric IP paths with plug-and-play simplicity. HD Link offers RF power to spare, an integrated IP gateway with sophisticated data handling capabilities, and multiple channels of audio. The intuitive front panel and remote interfaces tap into the most complete feature set of any microwave STL, yet take less time to configure. It can even operate on both RF and IP simultaneously, and allows automatic backup of all services from one to the other. Intraplex is broadcasting’s first choice for rock-solid, full-time operation of T1 STLs. With HD Link, you can now count on the same dependable performance, superior support and long-term value for your microwave links.

The Intraplex® IP Link family of IP audio codecs provides high-end features at an affordable price. Offering an array of audio coding options, the IP Link codecs are suitable for use in Studio to Transmitter Links (STLs) as well as audio contribution and distribution networks. Support for IP multicast and multiple unicast streams enables one encoder to feed multiple decoders. By incorporating three IP Interfaces that can be used for streaming and management, the IP Link systems can provide a level of reliability not seen in comparably-priced codecs. As the latest addition to the Intraplex family of audio transport products, the IP Link audio codecs bring legendary Intraplex reliability to the IP codec market.

Whether you’re looking for simple one-way audio transport or multichannel FM plus HD Radio™, control data, or off-premises extension telephones, there’s an Intraplex® STL HD package that’s right for you. STL HD is a modular family of products designed to let you customize your T1 STL with exactly the features and circuits you require. The system transports crystal-clear digital audio over any distance or terrain, and can be used on all types of T1 links, including leased telco T1 circuits, microwave, spread spectrum radio and fiber optic. STL HD systems can be equipped to carry one-way or full-duplex stereo audio, with or without compression. STL HD also provides a wide range of data interface options and supports a variety of telephone, intercom, and other voice-grade applications.

Unprecedented Flexibility in IP Audio Transport Intraplex NetXpress LX™ IP audio multiplexer delivers a high-performance IP audio platform in a scaled down, affordable package. Supporting both unicast and multicast, and compatible with the existing NetXpress, the NetXpress LX system opens up new possibilities in IP audio network design. Existing T1/E1 Multiplexer Conversion to IP Forget about retiring perfectly good Intraplex systems when moving from T1 or E1 to IP. The new NetXpress LX IP interface module, the CM-30, can replace the network interface module in existing Intraplex T1/E1 systems, converting them to IP while keeping the existing chassis with all of its audio, voice and data cards. Intraplex Reliability When the mission is critical, broadcasters turn to Intraplex audio transport systems — the standard-bearer for dependable, great-sounding audio links for always-on applications. Built upon the technology of the original NetXpress system, but with a form factor matching that of our T1/E1 systems, the NetXpress LX multiplexer provides the reliable and robust performance demanded by studio-to-transmitter link (STL) and other fixed, full-time inter-facility applications. Available in two sizes — a 3RU frame with capacity for up to 17 application modules and a compact 1RU frame that can hold five application modules — the NetXpress LX system can also work as an “edge” device along with the NetXpress multiplexer in large, multisite networks. The NetXpress LX multiplexer provides the superior support and long-term value expected from Intraplex — broadcasting’s first choice for robust, full-time operation of IP audio, T1/E1 and 950 MHz audio and data links.
