SCOOPY+ - User Manual

1. Presentation –Getting started

The SCOOPY+ codec allows the bi-directional transmission of one or two audio signals with bit rate

reduction, over various transmission media: ISDN lines, PSTN telephone lines, IP protocol networks…

The standard version of the codec includes an Ethernet interface for IP transmission. The unit can be

complemented with many options providing additional network interfaces, coding algorithms, etc.

One outstanding feature of AETA codecs in ISDN mode is the 5A System: on receiving an incoming

ISDN call, the unit can automatically detect the coding algorithm and parameters of the calling

codec, and then adjust itself in a compatible configuration so that the connection succeeds regardless

of the initial configuration and that of the remote unit.

In IP mode, the codec features the same ease of operation thanks to the use of the SIP and SDP

protocols.

This chapter gives basic instructions for a quick start. It obviously does not provide all the information

for full control. For comprehensive information one can refer to the rest of this manual:

Chapter 2 describes all the functions and features of the SCOOPY+ (but not necessarily with

all the operating modes)

Chapter 3 gives a physical description of the unit, shows its setting up and operation

principles.

Chapter 4 details menus and operating modes.

Chapter 4.11 deals with using the html server embedded in SCOOPY+

Chapter 6 provides all the technical characteristics of the SCOOPY+

The annexes bring miscellaneous additional information, including an index you can use to

look for a given information topic.

The following table shows the main features of the product. Functions marked with in this table are

available as options.

Table 1 –Main features of the SCOOPY+

SCOOPY+ - User Manual

1.1.

Install and connect ScoopY+

Plug on a power source or put 6 C batteries.

Turn SCOOPY + on by holding for >3 seconds. (Hold down for > 3 seconds to turn

it off!)

Connect the necessary audio interfaces (details: page 18)

Connect ScoopY+ on the transmission network (details: page 33 and following)

Using the ScoopY+ menus: key or key to activate the main menu, use the joystick to

select a sub-menu or a parameter, enter or validate with the key. jumps back up to

the previous menu level, until getting back to the base screen (with level display).

(details: page 41)

1.2.

Audio settings

With factory settings, all inputs are routed to the main program, and clipping level is set at

+12 dBu for both inputs and outputs.

Enter the menus using , select Setup then Audio. Perform necessary settings, see details

further on page 54.

1.3.

Select and set up network to be used: wired networks

Select network: Setup menu then Network, then select Change Network, . In the

proposed choice, select the desired network (ISDN, MOBILE, Ethernet, POTS). Validate

with .

Select the audio coding: menu Setup / Algorithm, then Other, then . Browse the

available choice with the arrows, and make a selection with . Restart the same procedure

to change for another coding setup.



The available choice depends on the transmission network! For more details on coding,

see page 14.

1.3.1. Set up an ISDN link

If needed, select the protocol with Setup / Network / ISDN Parameter / Protocol. More

details: see page 48.

Enter the remote number to dial, using the keypad, and press the key.

If more than one B channel is involved due to the coding algorithm used, you must enter a

second number, then , and so on. If the last dialled number is adequate, just confirm by

pressing without typing a number again.

Hang up with the key to release the connection (you must confirm by pressing again).

SCOOPY+ - User Manual

1.3.2. Set up a (wired) IP link

Over a public IP network, and especially when no SIP server is used, it is highly

recommended to use a STUN server.

The address of a STUN server can be set in the SCOOPY+ html pages (see page 88) or via the

menu: Setup / Network / AoIP Parameter / STUN Server, enter the address of a STUN server

(we propose our server stun.aeta-audio.com, look also the support pages on our web site

www.aeta-audio.com). Enable or disable STUN with Setup / Network / AoIP Parameter /

STUN Mode (On or Off).

More details: see page 113.

Check the Ethernet interface is active thanks to the LED on the Ethernet socket on the back,

and check an IP address is allocated: menu Tools / About / Local IP.

The default setting uses a DHCP server to get an IP address, which is suitable for most

occasions. In other situations, look for more details on page 36.

Using the keypad, enter the remote number to call (numeric IP address, or SIP URI if a SIP

server is used), then press the key.

Hang up with the key (you must confirm by pressing again).

When using a SIP server, some data must be entered beforehand using the AoIP Parameter

menu; for more details, refer to page 46.

1.3.3. Set up a POTS link

For connecting the line, you must plug the POTS line in ANALOG socket.

If needed, adjust the POTS line parameters using Setup / Network / POTS Parameter.

Details on these settings: see page 49.

Enter the remote number to dial, using the keypad, and press the key.

Hang up with the key to release the connection (you must confirm by pressing again).
