Page 13: Functions
2. Functions The following synoptic diagram shows the basic functions of the equipment. Figure 1 – Functional diagram of the equipment The audio signals to be transmitted are converted (when needed) to digital format, then the encoding function reduces the bit rate, using a selectable algorithm; the resulting bit flow is sent to one of the available transmission interfaces: Ethernet interface, ISDN interface, PSTN interface, mobile network...
Page 14: Transmission Interfaces
2.1. Transmission interfaces The SCOOPY+ features in all versions an Ethernet interface for IP protocol networks. One ISDN, PSTN/POTS and mobile network access is optionally available. 2.1.1. Ethernet/IP interface The IP interface is a 10BaseT/100BaseT Ethernet interface allowing transmission of the audio programmes in a wide range of possible bit rates.
Page 15 SIP and SDP protocols The SIP protocol is a signalling protocol, used for IP connections, which allows the SCOOPY+ to interoperate with IP phones and other SIP compatible audio codecs, in a way similar to ISDN or POTS connections. Details about the SIP protocols can be found in the annex (refer to 7.2, Overview of the SIP protocol).
Page 16: Isdn Interfaces
2.1.2. ISDN interfaces For access to the ISDN, the transmission interface is one S0 BRI (Basic Rate Interface), for transmission over one to two 64 kbit/s B channels. The codec synchronises itself onto the ISDN network clock when a link is active. Network protocols Available protocols: ...
Page 17: Pots Interface
It must be noted that, thanks to the interoperation protocol, J52 codecs, when setting up a link, can negotiate automatically and agree on a configuration that is compatible with the capability of both units (regarding bit rate, channel mode, etc.). In this way, when the units differ in their capability (or make), the resulting configuration may be different from expected beforehand, but in most cases the link will work and audio will be transmitted.
Page 18: Mobile Network Access
2.1.4. Mobile network access Units equipped with the “Wireless” option include an integrated module for access to 2G/3G/3G+ mobile networks, and a holder for a SIM card. Depending on the version the accessible networks are 2G (GSM, EDGE), 3G (UMTS), 3G+ (HSDPA, HSUPA, HPA…), and 4G/LTE.
Page 19: Managing Calls
Mobile IP mode The other service available with mobile access is the data packet transmission mode, abbreviated as “PS” (for Packet Switched), with IP protocol. This mode brings similar capabilities as a wired IP connection via the Ethernet interface, as described above in 2.1.1, with some distinctive characteristics: ...
Page 20: Audio Encoding And Decoding
2.2. Audio encoding and decoding SCOOPY+ features a wide range of coding algorithms. Their availability depends on the transmission network used.

Page 31: Auxiliary Functions
2.4. Auxiliary functions The main function of the SCOOPY+ is the transmission of one or two main audio programmes, but it also provides auxiliary functions for transmitting data or additional signals, inside the same stream (or, more generally, the same session). These features are only compatible with AETA products, because they are not inside the scope of independent standards.
Page 32: Transmission Of Relays
2.4.1. Transmission of relays You can transmit 2 states (Contacts) through a data channel during an establish link. These contacts can mange relay or “ON AIR” Lamp on the remote side. Note: In ISDN & POTS, the feature should be enabled on both sides. Some algorithms don’t support it in ISDN.
Page 33: Supervision And Control Interface
2.5. Supervision and control interface The control and supervision of the equipment (configuration, communication management, status monitoring), is carried out either “locally” thanks to a keyboard, an alphanumeric display, LED indicators, or using various remote control interfaces. 2.5.1. “Local” control For local management, the front panel includes a large keypad, a graphic OLED, and various LED indicators for essential status information.
Page 34: Test Functions
2.5.5. Test functions For maintenance purposes, some test loops can be activated. The following drawing schematically shows these test loops: Figure 5 – Test loops  “Audio loop”: uncompressed audio data are looped from the input of the encoder to the input of the output conversion functional block.

Page 42: Initial Setup Of The Ethernet Interface
3.4. Initial setup of the Ethernet interface The SCOOPY+ includes a 100BaseT / 10BaseT Ethernet interface, and the audio transmission can take place over an IP network through this interface. In addition, it is always possible to use the Ethernet interface to access the embedded html server or for remote control the unit via a TCP/IP connection (TCP port 6000).
Page 43: Optional Configuration Of The "Link" Ethernet Layer
You can then also check that the unit is seen on the network and at the right address: from a computer connected to the same network, enter (in the command mode, or console mode depending on the OS) “ping ipaddr”, where ipaddr is the IP address of the SCOOPY+. If the response is positive, then you can proceed with the rest.

Page 69: Setting Up Links In Double Isdn Codec Mode
4.5.2. Setting up links in double ISDN codec mode The double codec mode is specific, as the unit behaves as two independent G711/G722 mono codecs, designated “Codec 1” and “Codec 2”. Each codec sets or releases links separately on the B channel it is assigned, and uses the audio input and output it is assigned: input and output A (or “left”) for Codec 1, and input and output B (or “right”) for Codec 2.

Page 71: Setting Up A Link In Ip Mode Via Ethernet
4.5.3. Setting up a link in IP mode via Ethernet A link is set up in a similar way as an ISDN link. The difference is mainly that instead of the telephone number, we use either an IP address, or a SIP URI (Uniform Resource Identifier). Preliminary settings If a SIP server is used, the SCOOPY+ must be registered on this server.
Page 72 Receiving calls This is very simple, in both cases (direct peer to peer link or SIP server). There is nothing to do… When a call is received, the units negotiate automatically a commonly acceptable coding algorithm, and set the link automatically. On the receiving side, SCOOPY+ will “follow” the calling unit. ...
Page 73 Multicast mode transmission On a network that can support it , the multicast mode can optimise the resource usage when an audio stream has to be distributed simultaneously to several destinations. Contrary to the normal bidirectional unicast mode, this mode is unidirectional: one sender encoder sends a stream towards a multicast group address, and one or several decoders receiving the stream pick up the packets sent to this group address and decode the audio stream.
Page 74: Setting Up A Pots Link
4.5.4. Setting up a POTS link Preliminary settings The network interface must be configured depending on the PSTN line that is used, thanks to the “POTS Parameter” sub-menu (Setup Network POTS Parameter)  You should preferably disable services such as call waiting tones. Tone signals injected on the line during the communication have a high risk of disturbing the codec operation, and even dropping the link.
Page 75: Setting Up A Mobile Telephone Link
4.5.5. Setting up a mobile telephone link Prerequisites You must have a subscription and a SIM card granting access to mobile transmission. In the case described here the subscription must include access to the basic telephone service. Preliminary settings First insert the SIM card in the SCOOPY+ (the unit must be powered off for this. See how to proceed on page 34, “Drawer for SIM card [10]”.

 IT IS STRONGLY RECOMMENDED THAT YOU DON’T USE LOW QUALITY, SALT OR ALKALINE CELLS. SUCH BATTERIES MAY CAUSE LEAKS AND DAMAGE THE UNIT. 6.1.9. DC power supply Scoop+ will also work on any external 8 to 15-Volts DC source. A typical source will be a car cigarette adapter.
Page 109: Audio Performance
6.2. Audio performance The audio performance in this part applies to the system without coding/decoding, and excluding the coordination channel. The additional effect of the audio encoding and decoding on audio performance depends on the coding algorithm used and its parameters. Except when differently stated, the following measurements are done at a +6 dBu input level and on the AD/DA path, with maximum input and output level set at +16 dBu.
Page 110: Total Distortion Vs Frequency And Level
6.2.5. Total distortion vs frequency and level Total distortion relative to maximum level (or THD + N) is less than –78 dB over the whole audio bandwidth (20 – 20 000 Hz). This performance holds for audio signals from –80 dB to –1 dB relative to the maximum level (+16 dBu).

Page 116: Overview Of The Sip Protocol
7.2. Overview of the SIP protocol 7.2.1. What is SIP? SIP is for Session Initiation Protocol, a protocol specified by the IETF for establishing media transmission sessions. SIP is considered the communication protocol of the future by most vendors, and as such it has deep influence on the VoIP applications. As a signalling protocol, SIP brings methods and techniques to solve the issues related to the establishing of an audio link.
Page 117: Setting A Link Without A Sip Server
What happens then on the network: the Scoopy+ sends the request  (INVITE in SIP protocol) to a proxy server (often the same device is also the registrar). To make things simple, this proxy then relays and routes the request  to its destination. Resolving the SIP URI to a physical network and address uses mechanisms similar to those used for resolving URLs.
Page 118: Some Methods To Deal With Nat Routers And Firewalls
7.3. Some methods to deal with NAT routers and firewalls Problems arise when the desired connection has to go through a NAT router, and/or a firewall, that blocks a direct IP communication. This is a very common issue, especially if one needs to set up a transfer via the Internet. It is impossible here to describe in details the possible ways to deal with this problem, but the following just shortly discusses some typical solutions.
Page 119 NAT routing is an obstacle to transmission with UDP, mainly for two reasons:  It does not allow unsolicited data to come in from the outside network. In other words, data input is accepted on a port as an answer to a request from the local network, but an external agent cannot directly initiate the transmission of a packet.
Page 120 Standard NAT router Situation: codec A behind a NAT router with no specific programming (a codec accessing Internet via a mobile network is almost always in such situation). Besides, we assume that the other codec (B) is accessible with a public address. Once codec A is configured for using a STUN server: ...
Page 121 Once codec A is configured for using a STUN server:  codec A can initiate a connection to (call) codec B  codec B can call codec A, using the public address of the NAT router Advantages Drawbacks Each codec can set up a session Need to configure the router A is nearly equivalent to a codec with a direct Only one codec can be set up in this...

7.3.3. Summary and reminder of essential rules The table below sums up the situations where a link can be set up (not using a SIP proxy server) and reminds the needed specific settings: Codec A Possible Codec B Notes access calls access ...
