Intraplex® AudioLink PLUS™

E1 System for Contribution/Distribution Networks

Solve Today’s Challenging Content Transport Requirements
Radio engineers face the challenges of managing their broadcast program con-tribution 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 trans-mission 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 de-livers superior audio quality and efficiency to broadcast stations and networks worldwide.

E1 and IP — Build 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.

Harris® Intraplex is a world leader in E1 audio transport solutions, with thousands of systems in operation.

Features

  • Intraplex E1 technology
    Building on 20+ years of experience, 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 T1 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.

Specifications

Specifications and designs are subject to change without notice.

General
A typical shelf configuration consists of 1 chassis, 1 power supply, 1 or 2 CM-7RB E1 interface modules, and 1 or 2 module adapters (MAs), 1 for each CM-7RB. See E1 Inputs/outputs for MA options. Audio, voice, and data modules and redundant compo-nents are optional.

Shelf ConfigurationsADL-263 E1 terminal multiplexer contains 1 CM-7RB module with MA

ADL-265 E1 drop and insert multiplexer contains 2 CM-7RB modules with MAs, configured for drop and insert or drop and continue operation

ADL-266 E1 dual terminal multiplexer contains 2 CM-7RB modules with MAs, configured as 2 independent terminals sharing the same chassis
Module CompatibilityAccepts Intraplex plug-in audio, voice, and data modules. See individual module specifications for details and applications

Redundancy2 levels of E1 redundancy are available:

For E1 module redundancy where only 1 E1 circuit is available, a second CM-7RB module can be added that connects to the same MA as the primary CM-7RB

For E1 line and module redundancy where 2 E1 circuits are available, the system can be equipped with 2 CM-7RB modules and an MA-235 set, which contains 1 each MA-235-1 and MA-235-2, replacing the standard MA (available with RJ-48C connectors only)

Alarm ReportingMajor (alarm), minor (alert), NO/NC relay contacts
LoopbacksLine loopback, equipment loopback, payload loopback
Test AccessBantam jacks for E1 input/output signal and E1 input/output monitoring

Remote Access and Control
User Interface (Standard)Remote programming and monitoring using ISiCL (ASCII command-line interface), or Windows®-based IntraGuide® configuration and management software, which is provided with every system. IntraGuide® software updates are available to Intraplex customers from the Harris Broadcast customer support site at http://ecustomer.broadcast.harris.com.
