8. 5 1 INTRODUCTION 1 1 General description The AEQ PHOENIX STUDIO is a multiformat multi algorithm dual channel audiocodec designed for stationary rack mounted applications like links between studios or STL PHOENIX STUDIO is a stationary audiocodec offering the options of working over ISDN and IP networks among many others When used over the IP communications interface it is fully compatible with the EBU TECH 3326 technical specification issued by the EBU N ACIP working group This specification was developed to guarantee compatibility between devices made by different manufacturers for professional quality audio contribution applications over IP networks In addition to the Ethernet ports the device has two extra slots for inserting additional ISDN communication modules in this firmware version This modular design makes the PHOENIX STUDIO easy to upgrade in the future with new communication modules responding to the needs whose satisfaction the market may demand at any time The PHOENIX STUDIO enables its users to work simultaneously over two channels with professional quality in independent dual mono format or in stereo or combination of both The PHOENIX STUDIO is designed to ensure interoperability with existing and future communications equipment developed by AEQ and other manufacturers thanks to the large number of interfaces and encoding algorithms it implements and to the possibility of easily bringing them up to date as the market

Pin 14 SYNC_IN_AES Pin 15 SYNC_OUT_AES Considerations The signals containing audio and synchronizing information Channel 1 and Channel 2 are compliant with the AES 3 standard The signals that only contain synchronizing information Synchronism are governed by the AES 11 standard The synchronizing input signal can be used to change the sampling rate of the AES EBU output signal set by default at 48 kHz The synchronizing output signal will either repeat an external synchronizing input signal or will take the internal 48 kHz signal to the synchronizing input of other AES EBU equipment items When both of the two audio codec channels are used independently of each other the audio carried by each of them will be output through the connector corresponding to channel 1 or 2 2 2 5 V 35 interface DB25 physical connector DB25 pinout D E AEQ PHOENIX STUDIO 14 Allows an external terminal adapter TA to be connected at speeds of 64 128 256 kbps Two types of TA can be used V35 V11 interface Uses unbalanced asynchronous control signals while the synchronous clock and data signals are balanced Interface which at the physical level is compatible with X 21 RS422 protocol levels The pin out detail and the signals available in the DB 25 connector are the following Pins 4 and 5 equivalent to RS232 RTS and CTS signals are strapped internally The AEQ PHOENIX STUDIO can be configured to define

11. The frequency extension function allows you to transmit the 50 to 300 Hz frequency range over the telephone line To accomplish this the signal is subjected to a 250 Hz frequency shift which improves the quality of the received signal in its lower frequencies at the expense of the higher range The transmitted bandwidth ranges then from 50 to 3150 Hz The 250 Hz lost in the highest frequencies are not very significant due to the logarithmic nature of audio frequency response The frequency shift is accomplished through the encoding of the audio signal before it is sent to the telephone line On the receiving end the signal is decoded that is the reverse frequency shift is performed an operation that must be carried out by suitable equipment The decoded signal falls within the original range 50 3150 Hz without having suffered any sort of interference In this way greater depth and clarity is achieved in the voice signal even in those communications that take place under the worst conditions The physical interface is a standard RJ11 connector Detail of RJ11 connector POTS interface pending of development in future firmware versions AEQ PHOENIX STUDIO 18 2 4 2 SGA 03 communications module ISDN According to the UIT T the Integrated Services Digital Network ISDN can be defined as a network that has evolved from the Integrated Digital Network IDN and which provides end to end digital connections to deliver a wide range of ser
