AIP 6350 / Office 35IP 4.5.2 Registering Strategies The registering process allows 2 strategies for registering IP terminals with the system: • The systematic strategy • The Plug-and-Play Strategy 4.5.2.1 Systematic Strategy The assignment of the IP address to user-network interface and phone number is determined before the installation. Use this procedure is you are planning the installation systematically: 1. Fitting and registering the AIP card. 2. Use AIMS to enter the IP address of the AIP card.
AIP 6350 / Office 35IP 4.5.2.2 The Plug-and-Play Strategy The definitive assignment of the IP address to user-network interface and phone number is determined after the installation. 1. Fitting and registering the AIP card. 2. Use AIMS to enter the IP address of the AIP card. 3. Configure the local IP addresses in the IP terminals. 4. Connect the IP terminals to the network. The IP addresses of the IP terminals are assigned one after the other to the available user-network interfaces and then registered.
AIP 6350 / Office 35IP 4.6.2 Connecting an IP Terminal Elsewhere The following describes how to change the point at which an IP terminal is connected without changing the call number, subscriber name or the terminal settings. For this the PBX does not have to be taken out of operation: If the IP addresses of the IP terminal, the default gateway and the AIP card can be taken over unchanged, proceed as follows: 1. Unplug all the connectors on the IP terminals. 2.
AIP 6350 / Office 35IP 4.6.3 Expanding the System with IP Terminals The following describes how to expand the system with additional IP terminals. For this the PBX does not have to be taken out of operation: 1. Check to make sure that none of the following limits are exceeded as a result of the expansion: – Admissible number of system terminals on the PBX (a PBX upgrade may be necessary) – Admissible number of IP terminals per AIP card (another AIP card may be necessary).
AIP 6350 / Office 35IP 5 Expansion Card AIP 6350 The extension card AIP 6350 is identically as the extension card AIP 6400, however is provided with another software. 5.1 AIP Card AIP cards are installed in an Ascotel IntelliGate 2025, 2045 or 2065. Depending on the system one or more AIP cards can be used. Tab.
AIP 6350 / Office 35IP 5.2 DRS Module DRS modules are AIP-specific modules that are fitted to the AIP card. An AIP card contains 2 slots for DRS modules. DRS modules are required for the real-time processing of voice data. Two DRS modules of different sizes are available: • The DRS-04 module is capable of processing up to 4 voice channels simultaneously • The DRS-08 module is capable of processing up to 8 voice channels simultaneously Tab.

AIP 6350 / Office 35IP 5.4 haz0001aaxxa0 Installation of the AIP Card Warning: During the entire installation procedure, it is mandatory to observe the electrostatic discharge (ESD) precautions. The creation of an anti-static environment is highly recommended. Fitting the PBX with an AIP card: 1. Fitting an AIP card with DRS modules. 2. Disconnect the PBX from the power supply. 3.
AIP 6350 / Office 35IP 5.5 Connection on the AIP Card The AIP card is connected by a switch to the network. The PBX does not have to be switched off for this. For the connection the following cable is to be used: • Straight (1:1 through-connected) twisted-pair Ethernet cable • Category 5 or higher • With RJ-45 connectors at both ends. haz1080aaxxc0 PBX RJ45 PC RJ-45 AIP Switch PC Fig. 9: PC switch – AIP card connection Tab.
AIP 6350 / Office 35IP 5.5.1 V.24 Connection The serial interface (V.24) enables support specialists to monitor the traffic data. It has no function in normal operation. A crossed cable (null modem cable) is used to connect the PC to the AIP card via the serial interface (V.24). Tab.
AIP 6350 / Office 35IP 5.6 Commissioning the AIP Card When the PBX is switched on with a newly installed AIP card, the green system LED on the AIP card should start flashing (see Fig. 7, page 29). The network LEDs have the following functions: Tab.
AIP 6350 / Office 35IP 5.6.1 Changing the IP Address of the AIP Card via V.24 The IP and subnet address of the AIP card can be corrected without a password prompt via the V.24 access. 1. Start a hyperterminal session 2. Enter the following command line according to Tab. 16 and press "Enter": 3. Enter "reboot" and press "Enter" The card is started and the modified IP address is read in. Tab.
AIP 6350 / Office 35IP 5.7.2 Replacing an AIP Card The following describes how to replace an AIP card: 1. Use an AIMS Download to save the AIP configuration data (backup). (As this may no longer be possible if the card is defective, it is advisable to keep backups of the latest configuration on AIMS at all times.) 2. Replace the AIP card as described in the previous Chapter. 3. Start the PBX. 4. Log in with AIMS on-line on the PBX. The message "HW configuration has been changed" appears. 5.
AIP 6350 / Office 35IP 5. Use AIMS to allocate the call numbers of the IP terminals to the new port numbers (CM_1_1_3_Subscriber) so the subscriber data can be re-assigned. 6. Check the configuration using AIMS and unlock the card (CM_1_4_5_AIP Cards, Setting "AIP Card On/Off"). 7. Carry out a functional check. 5.7.4 Retrofitting an AIP card with DRS modules. An AIP card can also be retrofitted with DRS modules: 1. Disconnect the PBX from the power supply. 2.
AIP 6350 / Office 35IP 6 Network Environment This Chapter provides background information on the main network characteristics you need to take into consideration. It is assumed here that a network is already available. Please note that the expertise of an experienced network engineer is crucial for optimising the network environment. 6.
AIP 6350 / Office 35IP 6.1.1 Delay and Jitter High delay and jitter values have a considerably detrimental effect on the quality of speech. The delay values of the voice packets should be kept as small as possible. The following methods are used to reduce delay and compensate jitter: • Prioritising voice packets over other data packets: See the Chapter ("Prioritising", page 42).
AIP 6350 / Office 35IP 6.1.2 Bandwidth Management The available bandwidth can be limited, especially on WAN links. The bandwidth control of AIP 6350 prevents call connections from being set up if there is too little bandwidth available (see "Bandwidth Control", page 43). The following methods help to reduce the bandwidth requirement: • Voice compression: In the LAN area with sufficient bandwidth it makes sense to use a codec without compression (G.711) as the speech quality is better.
AIP 6350 / Office 35IP 6.2 Prioritising If the IP network is to guarantee the bandwidth required for call connections, voice packets have to be given priority compared with other data packets. The system supports the following prioritisation methods: • Expanded IP frames as per IEEE 802.1p/Q (CoS, Layer 2): AIP and IP terminals use the prioritisation field in the expanded frame header to specify the priority. Prioritisation is effected in the switches.
AIP 6350 / Office 35IP 6.3 Bandwidth Control The maximum number of call connections possible simultaneously can be limited using AIMS to ensure that the maximum number of call connections set up does not exceed the available bandwidth. The amount of bandwidth required by a call connection depends on the voice compression method. This method can be set for each individual IP terminal by selecting the correspond codec. The selected codec determines the bandwidth necessary for each call connection. Tab.
AIP 6350 / Office 35IP 6.3.1 Bandwidth Control Based on the Reference Model The following describes the procedure for defining codecs based on the example of the reference model and for setting up the bandwidth areas. An available bandwidth of 128 kbit/s is assumed as the measurement basis for the WAN link. haz1355aaxxa0 PBX 500 501 PSTN AIP 6350 IPI Router 2 LAN 2 10 Mbit/s 521 Fig.
AIP 6350 / Office 35IP 5. Specify the codec for the IP terminals in area 1. As there is sufficient bandwidth available between AIP and the IP terminals of area 1, G.711 can be used with a frame length of 10 ms. 6. Calculate how many voice channels can be open simultaneously between AIP and the IP terminals: 10 Mbit/s (LAN 1 bandwidth) 111 kbit/s (call channel with G.711 / 10 ms) = 90 voice channels In the maximum configuration with 4 fully equipped AIP cards the system supports 48 voice channels.

AIP 6350 / Office 35IP 7.6 Software Upload This Chapter describes the software uploading procedure for AIP 6350 and Office 35IP. AIP and IP terminals implement software which has to be adapted in the course of the product's further development (application software). The latest application software can be loaded on to the terminals using the AIMS Upload Manager. 7.6.1 Upload Process The Upload process for IP terminals is described below.
AIP 6350 / Office 35IP PBX 500 [1] 501 PSTN AIMS AIP [2] [3] WAN haz1364aaxxa0 522 [4] Fig. 13: 7.6.2 Software Upload Preparing the Upload The following preparations have to be made before you start the Upload: 1. Make sure you inform all users of the time at which the upload is scheduled to be carried out as phone calls cannot be made or received while the new software is being initialised. 2. Use AIMS to make a backup of the configuration data prior to the Upload. 3.
AIP 6350 / Office 35IP 7.6.3 Uploading To load different types of application software, first load the version for the PBX software, then the one for AIP, and finally the version for the IP terminals. In each case always wait until the current Upload is fully completed before initiating a new one. Next load the IP terminals with a new application software. For this, use the PBX internal FTP server (normal case).
AIP 6350 / Office 35IP 7.6.4 Uploading via an External FTP Server The load process of the application software of the IP terminals from an external FTP server is described below. The process for loading the AIP application software follows the same pattern and is not described separately. The new software is available in the form of individual files on an external FTP server.
AIP 6350 / Office 35IP 7.6.5 Upload Termination The Upload is terminated if • .. a predefined time limit (timeout) is exceeded, • .. the FTP server cannot be accessed, • .. the power supply is interrupted. The timeout can be set separately for the IP terminals and the AIP cards in the "Options/Settings" menu in the Upload Manager. The time indication relates to the Upload process for an IP terminal or an AIP card. The upload time required depends greatly on the network's transit rate.
