2. Programming tables for the 2N - OMEGA Lite PBX
The following passages give a detailed description of all of the programming
parameters in the 2N - OMEGA Lite PBX. The chapter is in the same position as the menu in the PBX configuration device’s themed index.
For access to programme the PBX you need a password. The PBX configuration instrument enables two types of users to change the PBX settings.
Password for a Supervisor user
The user with the supervisor authorisation has access to all of the PBX parameters and can also change the password for a user with user authorisation.
Password for an ordinary User
The user authorisation only allows certain PBX parameters to be changed when programming and the User password to be changed. All parameters are available for reading.
The user can change the following parameters
- Authorisation numbers
- Emergency numbers
- Bank holidays
- The name of the VL
- Internal priority lines
- Authorisation without ARS
- Allowing services – all
- Divisions
- Classification into groups and divisions
- Calling to the entire division
- FLASH and the type of choices for VL
- Allowing direct choice for bundles
- Operating parameters for internal and external lines
- Buttons for system telephones
- External lines – name and type of choice
- Bundles for ring retrieval
- Assigning ringing tables into the ringing table for external lines
- Labelling lines
- Switchover times
- Global group data – dialling tone, softening tone, DISA tone
- Quick dialling – joint and personal

2.1. Global data
2.1.1. Information This item informs you on the construction of the PBX that you are programming.
Here you will find the number of the SW version in the PBX, the production number of the PBX to which you are connected, the time for which access to the PBX by remote control is allowed and a precise labelling of the PBX firmware saved in the RAM and FLASH memory. This labelling is in accord with the file name used to upgrade the firmware in the PBX.
Information about licences:
RA Validity - expiring period for remote control with integrated modem to PBX
(according to main board type).
SW valid - SW validity expiring period (it is possible to make only emergency
calls after expiring of this period).
www.2n.cz
2N

Configuration instrument
ME valid - licence expiring period of Mobility Extension service. ME count - maximum count of Mobility Extension service users. (default users
count = 2, without validity limitation).
GSM validity – displays the time before licence expiry for call blocking from GSM modules (blocking of IMSI or first IMSI part). View the IMSI after the SIM card is read in the v LogSystem listing.
Last licence - shows the valid licence serial number. It is possible to download a licence with a serial number higher than the current one. Such a licence may be entered just once into the PBX.
To enter a licence, push the ‘key’ button on the main bar of the configuration tool. To create a licence, communicate the licence type, validity time and board number to the supplier.
Lines - displays the count of available ports for each interface.
Languages - shows the system language to be used (for accounting and
logsystem data listings and ME SMS messages as determined by the FW type: CZ = FW cz, sk, EN = FW en, de) and available user languages (for the key system menus and tags, extension names and personal quick dialling labels).
The last changes item provides information on the most recent data entered into the PBX or a file for each user type.

port.
Gap between numbers PV. Serves to assign the gap length for pulse dialling
sent to an external pulse.
DTMF dial length. Serves to assign the length of broadcasting the dual tone
multi-frequency (DTMF) dialling to an external port. This value also determines the DTMF dialling pause.
Waiting for a CPT CO. Determines the maximum period the PBX spends trying
to detect the external dialling tone used to determine the working of the external port.

Dial to GSM time. The maximum time for dialling another call to a GSM line. It
is renewed after every new number dialled by the internal user and, after it has expired; the device switches from dialling to calling. It is permissible for the expiration of this time to be marked by a short peep. Any other calling after this time has elapsed is considered to be a call service
Max call time without break-up. The maximum time for a call of two external
lines that have connected break up signalling.
Max call time with break-up. The maximum time for a call of two external lines
that do not have connected break up signalling.

accepted in the DISA direct inward calling. Increasing of DTMF resistant for VMail. Min. length of the DTMF sign that is accepted in VoiceMail. Amplitude of the DTMF L Group: the size of the DTMF sign’s amplitude (as a rule it is not necessary to change it). Amplitude of the DTMF H Group: the size of the DTMF sign’s amplitude (as a rule it is not necessary to change it)
The PBX has two tone generators which can be used as tone sources when setting Tones. The tone can be formed from up to three varying frequencies. When forming the tones it is necessary to uphold the rule on the overall size of the amplitude:
-1st Frequency = Amplitude to 62
www.2n.cz
2N
®
- OMEGA Lite
Configuration instrument
-2nd Frequency = Amplitude to 31
-3rd Frequency = Amplitude to 21
Generator 1 (sine 1) -Default frequency 425 Hz. Generator 2 (sine 2) -Example of forming a “British tone”. Amplitude of the voice modules
The default value is set at 64 and it is not recommended to change it. Busy tone detector parameters Count of CPT periods -minimum count of tones (beeps) according to
ITU-T E.180 before hang-up; Silence fluctuation -intensity of the silence signal (0-65535). Jitter period -tone duration tolerance against silence, starting from tone:silence = 1:1 [ms]; CPT detection threshold behind filter -minimum tone level (0-255) for the tone to be considered present.

2.1.14. Voices
Here you can change the voice settings (system, user and music to make
waiting more pleasant). System voices
The PBX contains 11 systems voices. The voices notify the user about being redirected, accepting the service dialled, a more expensive call in the LCR (least cost routing) etc... In this category there is also “music to make waiting more pleasant – MusicOnHold“. It is not recommended to make changes to the system voices.
User voices They are for notifying the caller in DISA.
After reading the DAT from the PBX this table will display a list of the voices contained in the PBX. Pressing the key “Load“ saves the voices in the “Wav“ directory, which are then automatically formed in the root directory of the installed PBX’s configuration tool.
If you are going to make changes in the voices settings it is necessary to first put the voice in this “Wav” directory and then set it here. A voice is a type of wav and must have the following parameters: MONO - 8bit - 8kHz - unsigned.
The overall capacity of the voices is ca. 3 minutes. The length of the system voices including the music is ca. 40 sec.

Each AUDIO input/output can be assigned one relay. The relay closes when the given AUDIO channel is used for the Tape recorder/Broadcast service.
Typically, this option is mainly used for Broadcast with the relay activating the so-called Broadcast exchange.

2.2. Internal lines
2.2.1. Numbering
This item offers a list of internal subscribers to the PBX. Here the individual ports are assigned a subscriber number and a name. The name is allowed to up to 14 characters, the numbering is 4 digits at most. Pay attention that no collision with the numbering of services arises.
In the DDI column enter the DDI number used when phoning an internal line during
DISA, DDI, if it is not set up otherwise in the ringing table.
Select the user language in the Language column to display the key system phone menus, line names and personal quick dialling labels. Select one of up to 4 languages as preset in the Global data/Localisation menu.
The Prefix CLIP column represents the transition sign to the VTS for internal lines that identify an incoming call and for system telephones with at least 05.12 firmware. It enables this equipment to accept call back directly from a list of rejected calls. It can contain up to 4 characters.
The column Prefix CLIP private represents the transition sign to a private network (an external line denoted as a private one) for internal lines that identify an incoming call and for system telephones with at least 05.12 firmware. It enables this equipment to accept call back directly from a list of rejected calls. It can contain up to 4 characters.

2.2.2. Access to external lines
2.2.2.1. Allocating external lines
This table is for allocating a selection of bundles for external lines to internal lines (analogue and system) subscribers. If an internal subscriber chooses the service Access to an external line and the LCR is not activated or they are returning from it because a different, cheaper route was not found, then for calling to the VTS the priority external line is first used and if the first choice is not available then the first free external line selected from the bundle. The priority line can even be from a disallowed bundle. If, for instance, we imagine 4 varying privileged groups of subscribers from the standpoint of their choices for a free external line (ignoring the LCR). The first circuit will be 2 internal lines to the flat of the building administrator, the second circuit to the director with an assistant and a company fax, the third circuit will be 4 traders and the fourth circuit the other employees with the lowest set selection for an external line. In order to meet these requirements we split up the external lines (except external lines allocated to GSM phones) into, for instance, 4 bundles. Bundle 1 has 1 external line – for the building administrator’s flat. External lines 2

and 3 – the directorate – are assigned to bundle 2. The external lines 4 and 5 are in bundle 3 and the last external lines, 6, 7 and 8 are assigned to bundle 7. Afterwards for starting up an external line we can assign the internal links from the administrator’s flat just to bundle 1. Like this no one else can get on this external link. For the director, assistant and fax we assign bundles 2 and 7 for starting up to the VTS. Like this two calls can be made simultaneously from the directorate on the private lines and other calls (faxing, other external conference calls , …) choose one of the free external lines from the last bundle, 7. Similarly the traders’ lines can be chosen from bundles 3 and 7 for external calls. The other employees can only use the last bundle, 7. In this case bundle 7 not only serves the group “other employees” but also as a reserve for the traders and the directorate with a fax. This selection can be enriched by setting the priorities for the internal and external lines. For the priorities the valid principle is that an internal subscriber must have the same or higher priority than an external line so that it can be assigned to him.
2.2.2.2. Authorisations
This table sets the authorisations for calling to a public telephone network in particular each internal line for the DAY regime, the NIGHT regime and private calls in an arbitrary regime. Here it is also determined whether a line will obligatorily use the LRC or not and what level of savings for route selection. If tables A – F are checked, then it means that the given internal subscriber controls the selection to an external network on the agreement of the number called with the values shown in tables A – F. If the number called is in agreement with the number in the prohibition table, the call is ended. If the caller has the prohibition table checked, then they can only call the numbers entered into the table. If the

combination and permission tables are combined then the permission table always has preference.
If the choice Use LCR is not checked, then after selecting the start up service to an external line the direct free external line is allocated without using alternate routes in the LCR. Without this choice the PBX behaves as standard. If this choice is checked so that after selecting the service start up to an external line no port picks it up, the caller receives a simulated external dialling tone and carries on. After every number called the selection is compared with the numbers in the Dialling Analysis table and at the same time the LCR level of the internal subscriber and the dialling analysis are compared. If a route is found then a call is made along it. If the route found is engaged or no alternative route is found at all or the level of the LCR is not in agreement then the call takes place along a standard external line with the announcement “Attention please, this call is more expensive”
Selecting the Obligatory LCR. If this box is checked it means the same as in the previous example, that after selecting the start up service to the VTS a simulated dialling tone is given and the number called is checked to see if it is not the same as a code in the Dialling Analysis table. If a number is dialled that is not in the Route Analysis then a connection is made through a standard external link. If agreement is found and the route is free, then the call is made along this route. In the event that the route is engaged, the caller is not allowed to make the call and receives the engaged tone or an announcement that the connection failed.
The selection Mask for Dialling Analysis – Level of Saving. Here up to 4 levels of saving. The individual rows in the Dialling Analysis also have 4 boxes for ticking the level of saving. So that the internal subscriber can get to the Dialling Analysis, they must have at least one box ticked for the level of saving in agreement with the row in the Dialling Analysis.
Note:
Setting the authorisations is independent of the LCR.
The selection Obligatory LCR must be selected at the same time as Use LCR.
Example 1: The subscriber is not allowed to call abroad. Then table B is ticked in which only one row is filled in with the value “00”. The other boxes are not ticked. Thus if they use “00” as the transfer sign to the international network then the call is ended. Example 2: The subscriber is allowed restricted external calls, they are not allowed 906, they can only get to GMS Paegas through the GMS phoning module. Then they have Tables A and B ticked, in which only rows are filled in with “00” and “906” and they also have the boxes Use LCR and Obligatory LCR ticked. At the same time we assume that they have the first of the four savings levels ticked and the row Analysis of Savings is also ticked at the first of the four levels. After dialling 603 it is found that there is agreement with a route though GSM and if the route is free then the call is made. The route analysis is filled in so that in one row there is the code 603 followed, for instance, by the number for route 1. Thus the route number is programmed as to which bundle is used and the entries for adding and removing numbers are left free (see programming the LCR). If the GSM route
