System Description 7
2 System Description
The joint use of the two IP components, namely the AIP 6350 IP interface card and
the Office 35IP system terminal, makes the IP infrastructure available to teleph-
ony, and expands the Ascotel IntelliGate platform to the IP data network.
The Office 35IP system terminal is a fully fledged IP terminal with the complete
range of features of an Office 35. It can be operated anywhere in the IP data net-
work, provided the connection to the PBX complies with the quality criteria
required for VoIP (Voice over IP).
Like any Office system terminal, Office 35IP communicates with the PBX via the
AD2 protocol. The features and user prompting are identical to those of the
Office 35.
The AIP 6350 is the PBX's Ethernet interface to the Office 35IP system terminals.
The expansion card from the AIP family has been designed specially for this appli-
cation.
Both the Office 35IP and the AIP 6350 are configured and updated using the
AIMS management software. All the settings can be made both offline and online
with the usual operating interface.

8 System Description
This key expansion option translates into a whole range of advantages for the
user:
• Networked, remote workstations can be integrated at low cost into the internal
telephone system, without compromising the ease with which phone calls are
made. Unlike a connection via the public telephone network, no call charges
are incurred and users can be reached as internal subscribers.
• Many features that are restricted when a remote subscriber is integrated as a
virtual subscriber can be used to the full, e.g. call diversions, Voice Mail, Cour-
tesy, text messages, announcements.
• In the case of smaller branch offices the customer can dispense with using an
additional PBX in the branch.
• When expanding an existing infrastructure with new connections for PC and
phones there is no need to expand the phone lines.
Note:
As a result of the expansion of the Ascotel IntelliGate platform to the IP
data network the network used becomes part of the Ascotel IntelliGate
system. The communication quality therefore depends directly on the
network quality (in the same way as the road network influences the
delivery quality of a haulage company).

10 Initial Installation
3.1.1 Designing the System
The following describes the procedure for defining the number of IP terminals you
want and the AIP expansion cards required for this purpose (see "Expansion Card
AIP 6350", page 29):
1. Specify the number of IP terminals.
2. Determine the number of voice channels required on the AIP based on the
anticipated traffic volume. Please note that during a call connection each IP
terminal involved requires a call channel to the PBX, as each connection is
routed via the PBX (Fig. 3).
3. Determine the number of AIP cards required (see "Overview of System Lim-
its", page 48):
– The maximum number of AIP cards that can be fitted depends on the PBX
model.
– One AIP card supports up to 16 IP terminals.
– The maximum number of simultaneously active voice channels per AIP card
depends on the DRS modules fitted.
4. Assign each IP terminal to an AIP card (each IP terminal must later be perma-
nently assigned to a fixed AIP card during addressing).
5. Check to make sure that the PBX system limits are not exceeded (see "Over-
view of System Limits", page 48):
– Number of admissible AIP cards.
– Number of admissible AD2 interfaces. One AIP card occupies 16 AD2 inter-
faces (see Ascotel IntelliGate System Manual).
– Number of admissible subscribers on the PBX (see Ascotel IntelliGate Sys-
tem Manual)

3.1.2 Assigning Call Numbers and IP Addresses
The following describes the procedure for sketching the IP terminals into your net-
work's current layout and assigning the call numbers and IP addresses.
Note:
The system operates with permanently assigned IP addresses. DHCP is
not supported.
1. Sketch the IP terminals into your network's current layout.
All the routers, gateways, firewalls and WAN links between AIP and the IP ter-
minals should be visible along with their IP addresses and subnet masks.
2. Enter the call numbers of the IP terminals.
3. Enter the IP addresses of the IP terminals and AIP cards.
The IP addresses must not have a relation to the call numbers. For the initial-
isation values of the IP addresses see the Chapter "Initialisation Values for IP
Addresses", page 48.
4. For each IP terminal enter the IP address of its allocated AIP card.
5. Enter the gateway address for each IP terminal. The gateway address is the
terminal-side IP address of the router that forms the transition to another LAN
area with IP terminals.

3.1.3 Network Planning
The following describes the procedure for checking your network and planning
the type of communications between AIP and the IP terminals.
Note:
– Please note that the expertise of an experienced network engineer is
crucial for assessing and optimising the network environment.
– We strongly recommend that you examine the network using a special
check-list, which you can download from our support page (asco-
tel.ascom.ch). Our specialists will be happy to assist you on the basis
of the completed check-list.
1. Check whether your network environment complies with our recommenda-
tions ("Bandwidth Management", page 41); if not, please take the necessary
measures to comply with the requirements.
2. Determine the prioritisation method in accordance with the Chapter "Priori-
tising", page 42.
With regard to initialisation values ToS is activated and CoS deactivated
(TOS is recommended if the voice connection is to be set up via a WAN link.
CoS prioritises voice traffic at the level of the switches).
3. Plan the bandwidth control in accordance with the Chapter "Bandwidth
Management", page 41.

3.2 Installation
The aim of the installation phase is to:
• Fit the AIP card(s) and connect them to the network.
• To connect the IP terminals to the power supply and the network.
• Enter the addresses on the IP terminals.
Proceed as follows:
1. Install the AIP card(s) as indicated in the instructions in the Chapter "Expan-
sion Card AIP 6350", page 29.
2. Install the IP terminals as indicated in the Chapter "IP Terminal Office 35IP",
page 20.
3.3 Configuring
The aim of the configuration phase is to define and set all the system parameters
using AIMS.
You can carry out the settings online directly on the PBX or prepare all the settings
in the offline mode and then load them onto the PBX. To do so please refer to the
AIMS online help.
You need to have System Manager or Installer authorisation to have access to the
configuration data.

3.3.1 Adding AIP Card(s) and IP Terminals
The following describes the procedure for complementing the AIMS master data
with the AIP cards and IP terminals.
1. In offline mode add the required number of AIP cards (card configuration;
CM_1_1_2). Make sure the slot selected in AIMS matches the slot actually
used in the system.
Once you have stored your inputs, AIMS will create 16 virtual user-network
interfaces1) with 2 connection possibilities each (MSN 1 and MSN 2) for each
AIP card. As a preconfiguration process AIMS automatically creates subscriber
data including call numbers on all MSN-1 connections.
2. Assign the names and correct call numbers to the subscribers preconfigured
by AIMS (CM_1_1_3_Interface Configuration).
3. Assign the IP addresses to the subscribers in accordance with the layout used
in the planning phase (CM_1_4_5_IP Terminals). Tab. 3 shows the settings
based on the example of the reference model.
4. Enter the IP address and subnet mask of the AIP card (CM_1_4_5_AIP Card).

3.3.2 Configuring the Default Gateway
To be able to reach IP terminals in other LAN areas, you need to enter the IP
address of the router via which the LAN area of the AIP is to be exited (default
gateway). This entry is superfluous if AIP and all the IP terminals are located in the
same LAN area.
You can define different default gateways for each individual IP terminal or for
groups of IP terminals. As only one default gateway is used in most cases, in the
following enter one default gateway for all registered IP terminals. For more infor-
mation please refer to the Chapter "Static Routes", page 46:
1. Create a static route (CM_1_4_5_Static Routes).
2. Enter the IP address "0.0.0.0".
– "0.0.0.0" covers all the registered IP terminals.

3.3.3 AIP Configuring
The following describes the procedure for configuring AIP based on the data
determined during the planning phase ("Network Planning", page 13).
1. Check the settings of the general network parameters (CM_1_4_5_AIP
Cards). See also Tab. 6.
2. Configure the parameters for prioritising the voice data (CM_1_4_5_AIP
cards). See also Tab. 6.
3. Configure the parameters for bandwidth control (CM_1_4_5_IP Terminals
and CM_1_4_5_Bandwidth Areas). See also Tab. 17.

3.4 Commissioning
The aim of commissioning is to obtain a correctly functioning system. For this we
suggest a functional test.
3.4.1 Checking the Installation
Check the following points before starting with the functional test:
• Have the IP terminals been successfully commissioned as indicated in the Chap-
ter "IP Terminal Office 35IP", page 20?
• Has the AIP card been successfully commissioned as indicated in the Chapter
"Expansion Card AIP 6350", page 29 (Link LED lit)?
• Has the AIMS configuration been carried out in full and has the configuration
data been loaded onto the PBX?
• Has the configuration of the switches and routers been adapted?

3.4.2 Functional Test
For the functional test we recommend that you put the system into operation on
a trial basis and check its operational suitability using a structured feedback from
all users. Proceed as follows:
1. Check the following points on each IP terminal:
– Do you obtain a dial tone when you pick up the handset?
– Are you able to set up a connection from the terminal?
– Can a connection to the terminal be set up?
2. In the initial operating phase check the call capacity and the speech quality by
asking the users to inform you of their experiences.
If the result is not satisfactory, have the network checked by specialists.
3.4.3 Troubleshooting
Try and ascertain whether the cause of the error originates in the PBX, the AIP,
the network, the IP terminal or in the interplay between these components. If the
fault appears to lie with.
• .. the PBX, please refer to the Ascotel IntelliGate System Manual.
• .. the network, call in a specialist to help you check the network configuration
and the network-related settings.
• .. the AIP or an IP terminal, check all the settings and connections as explained
this Manual.
The table below lists the most common error messages displayed on the IP termi-
nal and provides pointers on how to remedy them.

Like any Office system terminal, the system terminal Office 35IP communicates
with the PBX via the AD2 protocol. The features and user prompting are on the
whole1) identical to those of the Office 35.
4.1 Expansion Options
2 expansion keypads and one alpha keyboard or 3 expansion keypads can be
connected to an Office 35IP (see Operating Instructions for the Office 35IP).
4.2 Installation
The Office 35IP has the following external connections:
• Network connection
• PC connection
• Mains power supply unit connection
The terminal has an integrated switch (100BaseT), which can be used for
connecting the workstation computer. This means there is no need to install a
separate network connection point to operate the terminal.
Note:
The integrated switch is to be used exclusively for the operation of a PC.
– Do not connect any other terminals such as IP terminals, switches,
hubs, printers or servers.
