Intraplex® AudioLink PLUS™

E1 System for Contribution/Distribution Networks

OVERVIEW

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.

Main Features of Intraplex® AudioLink PLUS™

Intraplex E1 technology
AudioLink PLUS is the latest generation of Intraplex, continuing the tradition of unsurpassed reliability and state-of-the-art technology, while maintaining compatibility with earlier generations of Intraplex E1 systems. Hot-standby redundant power supplies and advanced E1 error mitigation techniques provide enhanced transmission robustness, making AudioLink PLUS a system you can rely on for years to come.

Audio transport
With AudioLink PLUS, uncompressed audio occupies just over half of the E1 bandwidth, leaving plenty of room for additional traffic in each direction. A wide selection of compression options, including Enhanced apt-X®, MPEG-2, MPEG-3, J.41, and G.722, allows the carrying of multiple audio channels on a single E1. Audio I/O is either analog or AES/EBU digital, while sample rates ranging from 16 kS/s to 48 kS/s provide for audio bandwidth options from 7 kHz up to 20 kHz and beyond.

Telephone links
A full range of telephone interface options allows the AudioLink PLUS to support a variety of telephone and other voice-grade audio applications, including 2-wire and 4-wire E&M for linking PABXs and KSUs, Off-Premise Extension (OPX) circuits that allow you to connect a telephone handset at the transmitter site to a PBX at the studio as if it were in the next room, and open 4-wire circuits to support talkback and intercom systems with both standard (3.4 kHz) and wideband (7 kHz) voice quality, as well as FSK tones for use with telephone keypad-operated remote controls.

Data circuits
The industry’s most extensive array of data interface options allows you to set aside part of your E1 to create a LAN bridge, carry IP data traffic, and link to virtually any type of control and data storage equipment. Available synchronous and asynchronous interfaces include RS-232, RS-449, V.35, X.21, TCP/ IP, UDP, TTL and more.
