August 2012 – Ed.1.2 Chapter 1 Description 1.1 General description EQUITEL E451 is an anti-vandal IP intercom based on VoIP technology. It is especially designed to be used in IP intercom systems. (1) It can be powered either through the PoE standard , thus simplifying the unit installation and maintenance, or by using a standard auxiliary power supply. The most important characteristics of this equipment are: • Double Ethernet 10/100 Base-T/TX interface, one of them compatible with the PoE technology.
August 2012 – Ed.1.2 The general architecture of an intercom network, based on Voice over IP communication standards using E451 systems, can be depicted as follows: Figure 1. IP intercom system scheme with E451 units Each E451 unit is connected through the Ethernet interface to a VoIP network, in which there may be a PBX, physical SIP telephones or software based (softphone) and a controller.
August 2012 – Ed.1.2 1.1.2. SIP mode with PBX E451 intercom incorporates a SIP agent that allows sending and receiving calls directly from an IP phone (2) using the SIP protocol through a PBX, should the equipment have been configured to work in this mode. A controller is optional in this mode, although by using one it would be possible to supervise the calls established through the SIP protocol, in order to register them. 1.1.3. P2P-SIP mode This mode is similar to the previous one.
August 2012 – Ed.1.2 The equipment can be PoE powered. This allows the unit to be powered using the same cable employed for the network connection. With this, we avoid the need of using sockets in those places where the intercom E451 is installed. Furthermore, in the case of not having a PoE Ethernet, it is possible to use a +9 to +14 V DC auxiliary power supply. Optionally, the unit can be powered at +24 V DC. If so, please contact EQUITEL commercial department or in support@equitel.es 1.

August 2012 – Ed.1.2 Chapter 2 Mechanical mounting This chapter is devoted to the mechanical aspects of the equipment for its installation afterwards. 2.1 Materials and dimensions E451 is composed of main pieces: 1. Galvanized steel sheet box. Dimensions: 200 x 120 x 56 mm. 2. Stainless steel box. Dimensions: 220 x 140 x 1.5 mm. 3. Aluminum middle plate. Dimensions: 220 x 140 x 2 mm. The front elements are anti-vandal: button with LED and screws. Figure 8.
August 2012 – Ed.1.2 2.2 Installation E451 is supplied with the box closed. Therefore, when installing it first of all we have to remove the 4 antivandal screws having a point for a special screw-driver ( 1 in Figure 9). This way, the equipment is separated in two pieces (see Figure 9): PIECE 1: Electronic board and loudspeaker attached to the aluminum middle plate. The latter is fastened to the stainless steel front and is locked with the anti-vandal button crossing both of them.
August 2012 – Ed.1.2 In order to install the sheet metal box, we have to do an opening in the wall selected for mounting the intercom E451. The box must be plastered at the surface level and placing it straight since when mounting it there will be no more orientation possibilities. The necessary cabling for the E451 Ethernet and power connections must be carried out through the holes in the box intended for this purpose ( 8 in Figure 9).
August 2012 – Ed.1.2 Chapter 3 Functionality In this chapter we will detail the IP intercom System functionalities based on the modules E451. We will explain separately each one of the possible operation modes in which E451 can be configured; the event chains taking place in each case; the pre-recorded audio messages used,… 3.1 Proprietary mode 3.1.1.
August 2012 – Ed.1.2 3.1.4. Audio communication closing To close an audio communication previously established, the controller must send the message of “STOPAUDIO”. E451 will send the corresponding ACK (“ACK_STOPAUDIO_CLOSED”, “ACK_STOPAUDIO_NOCLOSED”). This way, the controller will be able to know if the unit has the audio closed or not. The LED switched off indicates that the audio circuits are correctly closed. 3.
August 2012 – Ed.1.2 However, optionally it can be added a controller to this network (see Figure 11), consisting on a computer running the appropriate software. It is possible to use a demo application supplied by EQUITEL. In the working mode with SIP protocol, it just supervises the established calls in order to register them and controls the auxiliary outputs and inputs. (see points 1.9 and 1.10 ). 3.2.1.
August 2012 – Ed.1.2 1. When an E451 receives a request for establishing the communication and it has detected no problems (such as audio codification not supported by E451, line engaged,...
August 2012 – Ed.1.2 3.3.2. P2P-SIP network communication process Sending and receiving a call; the audio interchange and communication closing are made in the same way as in the SIP mode with PBX explained in the former chapter. For more details please consult the points: 3.2.2, 3.2.3, 3.2.4 and 3.2.5. In this model, the button has also a triple functionality: to call, to answer a call and to hang up. 3.
August 2012 – Ed.1.2 Chapter 4 Auxiliary input and output control In this chapter, we will explain how to read the auxiliary input and how to update the dry contact output available in E451. These contacts are physically accessible in some connectors, as described in the points 1.9 and 1.10 . Through them it is possible to connect other external devices. 4.
August 2012 – Ed.1.2 Chapter 5 Configuration through web server E451 has integrated a web server that allows accessing the configuration parameters from a remote site by connecting through a Web browser. The equipment is factory default configured with the following network access parameters: IP: 192.168.1.1 Subnet mask: 255.255.255.0 Gateway: 0.0.0.
August 2012 – Ed.1.2 The access menu to the different server pages is in the left side: • Home: Information about the system. • Network: Page for the network configuration. • Working Mode: E451 can operate in any of the three operation modes we have formerly explained. In this page it is selected the working mode.
August 2012 – Ed.1.2 Figure 14. Network configuration 5.3 Working mode configuration In this page we select one of the 3 possibilities that E451 offers to implement an IP based communication. As we have previously explained, we have to choose one working mode out of the following three ones: • Proprietary Mode: the communications establishment is done through an EQUITEL proprietary protocol (see point 3.1 .
August 2012 – Ed.1.2 Figure 15. Working mode configuration. SIP with PBX mode In the case of selecting the SIP with PBX mode (see Figure 15) it is necessary to configure some parameters of the SIP agent that E451 has integrated: • SIP Proxy IP: This is the IP address or PBX name. • SIP Port: This is the PBX SIP port; the standard being 5060. • SIP Registration Timeout: Measured in seconds, this is the register expiry time of the unit in the PBX. Values from 90 to 9000 seconds.
August 2012 – Ed.1.2 Figure 16. Working mode configuration. Mode P2P-SIP To use the P2P-SIP mode (see Figure 16) it is necessary to configure the following parameters: • Authenticated User: This is the extension assigned for the E451 intercom E451. • Destination Number: This is the extension of the SIP device to which we wish to call by pressing the user button. • Destination IP: This is the SIP device IP address associated to the extension previously configured.
August 2012 – Ed.1.2 5.4 Audio configuration Figure 17 is a snapshot of the audio configuration page. We can configure the input and output audio levels, the activation of the acoustic echo canceller functionalities and update the prerecorded audio messages.
