Installation Instruction ASB 150 02 > Boards for ASB 150 02

## IPU (ROF 157 5133/1)

In order to install the IPU, the following steps have to be performed:

1. Verification of the prerequisites to the customer LAN environment
2. Board setup
3. Board positioning
4. Connection to the LAN
5. Setting up the the Trunk Gateway.
   Program the IPU and the required network functionality, as described in document ’Networking via VoIP-lines, (366/15534-ASB 150 02 Uen)
6. Setting up the IP-Extensions.
   Program the IPU, as described in document IP-Extensions, (270/15534-ASB 150 02 Uen)

#### Verification of the prerequisites to the customer LAN environment

The following prerequisites should be clarified with the LAN administrator at the customer site before connecting the ASB 150 02 system to the LAN:

##### Physical LAN access

The LAN socket used for the ASB 150 02 IP access shall be near to the BusinessPhone cabinet (5 or 10 metres when using the cable TSRBS 902 007/x). The cabling between the Intranet and the Socket (RJ 45 connector) shall be wired for 100BaseT connections. We recommend that the cable is UTP Category 5 as minimum requirement.

##### LAN environment

The ASB 150 02 provides an interface to an Ethernet 10BaseT/100BaseTX autosense LAN environment according to IEEE-802.3 for half- and full duplex operation

##### Network protocol

TCP/IP, IP Version 4

##### IP address administration

ASB 150 02 supports a static IP address, BOOTP or DHCP. When using DHCP it is a must, that for the
ASB 150 02 system and its related unique MAC-address (can be read out directly from the board) a dedicated IP-address is defined in the DHCP server.
If there is no dedicated IP-address, the DCHP server always assigns a new IP address after each
ASB 150 02 system or IPU board restart, which automatically requires a re-configuration of all PNR tables in the other network nodes.

Note

When changing a faulty IPU board, the BOOTP and DHCP server have to be updated with the new MAC-Address

The MAC-Address is stated on a sticker which is located on the front panel of the IPU (see drawing IPU (ROF 157 5133/1) ). The MAC-Address can also be read out via command 2159.

##### Bandwidth

In order to avoid speech delay variation or conversation interruption (due to packet loss) the traffic situation on the LAN segments used for the VoIP lines should be analysed. Depending on the selected voice transmission quality, a certain bandwidth will be occupied per voice call. See ’Codec/Bandwidth and packet size table’ in document ’Networking via VoIP-lines, (366/15534-ASB 150 02 Uen)

##### Quality of Service

To provide Quality of Service for Voice over IP calls, the IPU supports "Type of Service" (priorisation of voice packets) in the IP header. It has to be verified, if this service is supported and programmed on the routers in the LAN environment. If the service is not supported by the routers, the voice packets will be sent transparently without any prioritization, which might result in some speech delay, related to the current LAN traffic.

#### Board setup

Before placing the IPU into the cabinet, the board has to be equipped with the compact flash card; optional DSM modules and the settings of DIP-switch X400 have to be verified in order to match with the used backplane

##### Compact Flash Card

The Compact Flash Card is used to store the IPU application image as well as the license of the enabled
bi-directional voice channels, see document Maintenance Instructions (1541-ASB 150 02 Uen)

Note

In order to be able to use all licensed voice channels, an appropriate number of DSM1 submodules must be mounted, supporting this amount of channels.

Plug the Compact Flash card into the position x300 according to the drawing IPU (ROF 157 5133/1).

##### Digital signal processing modul (DSM)

Apart from the Compact Flash card, the IPU has to be equipped with DSM submodules. The number of supported voice channels depend on the type of the DSM module,

Article number | Function
ROA 219 5114/1 | DSM1 - 12 bi-directional voice channels independent of used voice codec.
ROA 219 5114/2 | DSM2 - 16 bi-directional voice channels, independent of used voice codec.
ROA 219 5114/3 | DSM3 - 16 bi-directional voice channels, independent of used voice codec.

Mount the the DSM submodule according to the drawing IPU (ROF 157 5133/1).

##### DIP Switch position x400

Due to different pull-up values for the HSSC communication link on BDV 113 08 and BDV BS 101 0x cabinets, it is necessary to turn on an additional pull-up resistor, according to the following table.

Switch 1 | Switch 2 | Backplane type
on | off | BDV 113 08 (BP 250) PUB 5 in combination with PUB 6
off | off | BDV 113 08 (BP 250) PUB 6
on | off | BDV BS 101 0x (BP 50,BP128i) PUB 50, PUB50/19

#### Board positioning

Place the IPU into the cabinet according to the rules mentioned in chapter Placing of boards.

#### Connection to the LAN

Connect the IPU to the LAN by using the cable TSRBS 902 0007/1 or /2, whereby the Ericsson plug is connected to the position 6/1of the IPU.
