1. EQUIPMENT DESCRIPTION 1.1. Basic design concepts The EAGLE is a multi-format dual audio codec for ISDN lines. Offering, in a single unit, the entire set of utilities needed to establish either two independent two-way mono audio circuits, or one stereo, or one 20 kHz mono circuit between two remote points, with top sound quality and ease of use. Along with each audio channel, a transparent two-way end-to-end data channel can be enabled.
1.3. Encoding Algorithms. Main function of the AUDIOCODEC is to establish one or two bidirectional audio channels between distant points for receiving a telephone chronicle, for transmitting with a high quality a sports commentary voice or for establishing an audio link between two studios. In the remote site, a telephone or another AUDIOCODEC will receive the encodec audio and will decode it into audio signal.
In the following Coding Algorithms, the Eagle both, transmits and receives on the same Encoding Algorithms: - G.711: By using this algorithm it is possible to generate and receive voice calls, and to establish communication through ISDN with telephone numbers or lines pertaining to the basic and analogue telephone network (PSTN). - G.

It is possible to filter which EAGLEs will appear in the control screen. This mode is useful when many users from different studios have to control different EAGLEs from the same E@sy network. This option is configured in ‘FILTER’ section of the eagle.
6. FIRMWARE UPGRADING WHEN UPGRADING? This EAGLE has the latest firmware version available when it was manufactured. However, it is possible than in the future, new firmware versions will appear adding new features to this codec. These software versions will be published on AEQ web site: http:\\www.aeq.es\ PRECAUTIONS BEFORE UPGRADING: Firmware upgrade process is a delicate process and it is recommended to take some basic precautions before doing it.
6.3. OPERATION IMPORTANT Upgrading software has to be used separately from the server/remote control software. Double click on the icon to start the application: Program window will open and looks like this: In the File/Setup PC option, communications port of the PC that is going to be used has to be selected. In the same option, Range window is used for specifying the range of nodes to search for.
To upgrade the whole EAGLE, you have to select it and click the right button of the mouse. Open option appears. When we click this option with the left button, an explorer window appears for specifying the AFP (AEQ Firmware Pack) file with the new firmware versions. After specifying the path and name of the file, upgrading window opens and the software upgrades the modules automatically (the system checks the firmware versions installed and, if there are changes, loads the new version): In this picture, 3.
IMPORTANT The right order to upgrade the modules one by one is DSP – MICRO – TA. To upgrade one of the modules, you have to select it and click the right button of the mouse. Open option appears. When we click this option with the left button, an explorer window appears for specifying the new AFU (AEQ Firmware Upgrade) file.

A.2. ISDN NATIONAL-1 communications guide (USA) 1.- Notes about the ISDN and the peculiarities of the different types of ISDN 1.1.- Generalities about the ISDN The ISDN (Integrated Services Digital Network) is a telephone connection system that permits the establishment of fully digital end-to-end communications. There are two types of ISDN links, depending on the number of 64 Kbps channels: Basic links (BRI – Basic Rate Interface) and Primary links (PRI – Primary Rate Interface).
The Eagle’s Universal Terminal Adapter can work with the NATIONAL-1 protocol (the most widely used in the USA). Selection of the desired protocol, in our case the NATIONAL-1, must be configured in the unit’s setup. In Europe and in other geographic areas, there is a protocol called EURO ISDN. There are minor differences between the EURO ISDN in different countries. These differences do not affect the Eagle. 1.4.- Directory Numbers (DN’s) These are the telephone directory numbers assigned to the line.

A.4. ANCILLARY DATA CHANNEL AEQ audio codecs have the capability of inserting a configurable, two-way, transparent end-toend auxiliary data channel in communications that have been established. The link used by audio codecs on which the data channel is defined may be ISDN (64 Kbps or 128 Kbps), or using the V35/X21 interface (64 Kbps, 128 Kbps or 256 Kbps in some models) connected to modems or external terminal adapters.
PORT CONFIGURATION The external device that transmits and/or receives data through the data channel will be connected to the audio codec using the RS232 ANCILLARY PORTS; a RS232 cable like this will be used: PC EAGLE Tx Rx GND CTS RTS Tx Rx GND RTS CTS Consult ANCILLARY CHANNELS pinout in chapter 3.1 of this manual. HARDWARE CONFIGURATION There are two operating modes of the data channel.
In summary: The external equipment will be connected with a fixed baud rate of 115200 or 9600 or 4800 or 2400 or 1200 bps to the ANCILLARY port of the audio codec. The audio codec will establish a permanent link at 256 Kbps, 128 Kbps or 64 Kbps with the remote audio codec, selecting an operating (audio encoding) mode that allows the use of the data channel. Configuration of the data channel will be done selecting the effective bit rate, and enabling tx, rx or both.
In H221-H242 mode, compatibility with the ACD5001, MPAC-02 and TLE-02D is achieved by using CUSTOM programming with a value of 0. In G722, H221-H242 and AEQ3.5 modes, it is important to select the same effective bit rate at both ends. EXAMPLES A) When you want to transmit a data channel at 19200 between two PC’s through a communication between two EAGLES, you must: Configure the serial port on both PC’s at 115200.
A-5 ISDN BACKUP FACILITY. A new operating mode allows using the EAGLE over leased lines through the v35 port, in the way that, if this connection fails, the codec will detect it and automatically make an ISDN call as a ‘backup’ line of the main one, so the audio link is restored. Setting microswitch #1 in the UP position activates this mode. To deactivate this mode, this switch has to be set DOWN. All changes will be effective next time the EAGLE starts up.
The EAGLE will monitor v.35 clock signal and will stop ISDN communication and re-start to restore main v.35 connection five seconds after it detects v35 clock signal is again in the interface. The V.35 connection has the higher priority because the ISDN is used only when the main connection fails. The EAGLE that receives the call has to be configured as automatic off-hook. In order to test that backup system works, we recommend to turn off v.35 terminal. Never disconnect v.
A.6. Installation of the EAGLE as an ISDN hybrid. In some cases, the EAGLE audio codec is installed in a radio studio in order to replace an analog hybrid, as the AEQ TH-02 Ex MkII, for using ISDN lines. Connection of an EAGLE to an AEQ BC-500 MIXER: In order to connect an EAGLE to a BC-500 mixer, two BC533 (without internal hybrid) modules are used. First audio channel input and output will be connected to the first BC533 (Configured as PHONE 1 bus).
Connection of an EAGLE to an AEQ BC-2500 MIXER: In order to connect an EAGLE to a BC-2500 Mixer for using the hybrid features, module BC2533 is used. It is possible to connect the EAGLE to one BC2533 or two BC2533. Connection of an EAGLE to ONE BC-2533 channel: In this configuration, with two BC2533 and two EAGLES, there can be up to 4 calls in conference. As the BC2533 has only one audio input and output, it will be connected to EAGLE first line. The EAGLE has to be set to MULTIPLEX.
Connection of an EAGLE to TWO BC-2533 channel: In this case, both channels will be used as independet and the mixer will do the multiplex in case it is needed. In order to configure remote control, the following programming bridges of the BC2533 has to be set: PDP 7 and 10: ON PDP 8, 9, 11 and 12: OFF (removed) In the proposed cable diagram, each EAGLE channel is controlled by the upper part of the remote buttons of each BC2533: EAGLE - ANNEX A.6.
