The Port Number field id enti fie s the MCU port to which the MGC Manag er i nit ial ly connects. If the Automatic Discovery option is enabled, then after initially connecting to the MCU, the system checks the system configuration file (system.cfg) for the preferred port settings. The preferred port is defined in the GENERAL section of the system.cfg file, in the PREFERRED_PORT flag. If the preferred port differs from the currently connected port, then the system disconnects and reconnects using the preferred port and replaces the Port Number with the preferred port.

6. To manually define the Port Number, clear the Automatic Discovery

check box.

7. In the Port Number field, select the listening port number from the drop

down list. The default port number is 5001. The Internet Assigned Numbers Authority (IANA) has assigned port number 1205 to MCUs In new installations, it is re com mended to select the IANA port (1205). If you are upgrading an existing installation and you do not wish to change the firewall configuration, use the default setting (5001).

Defining a Secured (SSL) Connection to the MCU

SSL (Secure Socket Layer) enables secure HTTP connection on MCUs with XPEK Operating Systems. An SSL Certificate is required to enable SSL-level security for the MCU’s connection to external applications. SSL uses a third party, that is the Certificate Authority, to identify HTTP transactions and secure them using the HTTPS protocol.

The SSL certificate must be obtained on first connection to the MCU, once the MCU is defined in the MGC Manager application.

The first time you install t he MCU, if you are movi ng t he MC U to a different location, or if the MCU is located in a different time zone from the MGC Manager, you have to set the MCU date and time to synchronize the MGC Manager.

The time format used in the MGC Manager is taken from the Operating System installed on the PC running the MGC Manager. This allows 12-hour AM/PM and 24-hour formats to be used.

You can set the MCU time manually, or automatically either by updating it according to the MGC Manager application or synchronizing it with an external NTP server. The synchronization with an external NTP server is available only for MCUs with XPEK operating syst em and it en ables accurate time calculation that is essential for cascaded or recurring conferences.

To set the MCU date and time:

1. Connect to the MCU.

2. Once connected, right-click the MCU icon, and then click MCU Time.

Providers of communic ation services such a s telephone carriers use dif ferent communication protocols, lines, equipment and configurations. This can be true even in different regions of the same country.

The MGC unit is designed to work with different service providers/ communication lines. In particular, the MGC unit can be connected to any public or private network that supplies ISDN lines, ISDN leased lines, T1–CAS lines, ATM connections or IP connections. These include long distance carrier services and local area services. In addition, the MGC unit may be connected to a serial network usin g the MPI ser ial networ k inter face card.

To enable the MCU to connect participants using any of the following networks: ISDN, PSTN, T1-CAS, ISDN-NFAS, ISDN-Leased Lines, IP, serial connection (MPI) and ATM, the network parameters must be defined in the Network Services. You must also set up the network parameters whenever you:

• Connect the MGC unit to a switch in a new site

• Add a new switch to an existing site

• Add ISDN/T1–CAS lines to the system

• Connect the MGC to an additional LAN zone

• Change the network properties

Only MGC Manager operators with Superuser rights can perform MGC Manager configuration tasks. In addition, the user must have Superuser rights on the computer on which the MGC Manager application is running, or any other permission than enables the application to access the Registry (read/ write) and read/write files on the C: drive (root directory), under the Windows directory folder.

MGC Administrator’s Guide

Leased lines are communication lines that are dedicated to specific participants. In the Leased Lines dialog box, you select the participants that will be as signed to this line. The number of ports allocated to each participant determines the line rat e to be used in multiples of 64 Kbps, and it depends on the endpoint capabilities. For example, if the participant's capabilities a llow a line rate of 384 Kbps (6B), the participant will be assigned six (ports).

b. In the Partici pa nt Name box, enter the participant name. c. In the First Port box, enter the sequential number of the first port

(channel) in the range of channels to be assigned to this participant.

d. In the Last Port box, enter the sequential number of the last port

(channel) in the range of ports (channels) to be assigned to this participant.

For example, if the line rate to be assigned to t his participant is 384Kbps, assign 6 ports. If this is the first participant you are defining, you may define the range by indicating the first port as number 1 and the last port as number 6. However, if this participant is not the first participant to be defined, the first port number will have to be the next available sequential number. For example, if the last port defined for a participant is 16, the first port number to be assigned to this participant is 17.

e. Click OK.

The participant’s name is added to the Leased Lines list.

MGC Administrator’s Guide

Defining ISDN Non-Facility Associated Signaling (NFAS)

Non-Facility Associated Signaling (NFAS) only applies to T1 lines and can be configured in two different ways, depending on the ISDN network cards installed in your MCU.

Each T1 span has 23 B channels for tra nsferring audio, vide o, or dat a and one D channel. The D channel acts as a signaling channel, and controls the call activity.

In systems using NFAS, when you have a Net-2/4/8 card installed in your system, only one D channel is used. The other spans share the D channel, and this enables each additional PRI line to use the D channel as a B channel for audio, video, or data.

The span containing the D channel is called t he Master. The remaining sp ans, which share this D channel are called Slaves, and the number of B channels on each Slave line is increased to 24.

The Net-8 card has certain limitations in that you cannot aggregate PRI lines from another Net-8 card. This means that the maximum number of Slave spans that can share a Master span is seven, allowing for eight spans in total.

If you are using a Net-T1 card, several PRI lines on different cards may be aggregated to create one span. In such a case, one D channel controls the call activity for all the aggregated PRI lines - the Master. The remaining D channels are used to transfer call data (video and audio data), hence increasing the number of B channels (from 23 to 24 channels for each Slave PRI line) that can be used for video conferencing. You can, however, aggregate Slave spans from different Net-T1 cards to share with one Master. Theoretically, you can have up to 10 Net-T1 cards having 19 Slaves sharing with a Master (20 spans in tota l). H owever, it is not practical to have s o many Net-T1 cards connected to an MCU at any given time.

control the data flow for all the PRI lines bundled as NFAS.

— Slave - The PRI line that is used for data transfer (audio and video

information), increasing th e line rate that can be used to ru n conferences.

• There are certain li mitati ons when using a Net-8 card. The firs t number should

be that of the Master, and is always 0. The order in which you define the remaining PRI lines (the Slaves) determines the order in wh ich the lines will be used for running conferen ces. The NFAS ID number of the first Slave is 1. The ID numbers for each successive PRI line that is added as a Slave is sequentially increased by 1.

• If you are using a Net-T1 card, the NFAS ID number that you allocate to the

Master and Slave PRI lines is not important. It is however recommended that you enter 0 for the Master and increase this number by one sequentially, for every additional Slave that you define.

• The ID numbers assigned to each span must be identical to the ID numbers

configured on the switch in order for the system to recognize the data flow on each channel.

Assigning the T1-CAS Network Service to the Net-2/Net- 4/Net-8 Card

In order to connect the MCU to the network switch, you need to assign the T1-CAS Network Service to the appropriate span of the Ne t-2/Net-4/Net-8

Network Interface module.

It is not possib le to mix an ISDN Netw ork Se rvi ce and a T1-CAS Network Serv ic e on the same Net-2/Net-4/Net-8 Network Interface module. Therefore, the Net-2/ Net-4/Net-8 card can only be used with either ISDN or T1-CAS Network Service. Before you assign the T1-CAS Network Service to the card, you must set the following ‘system.cfg’ flag: in the NET8_PARAMETERS section, set NET8_DEFAULT_TYPE = to T1-CAS.

In addition, you may define which span in the network interface card is used as the primary clock and which one as the backup clock in order to synchronize with the network clock.

T o assign the T1-CAS Network Service to the Net-2/Net-4/Net-8 Network Interface module:

1. In the Browser pane, right-click the slot containing the Net-2/4/8 card,

and then click Properties. Alternatively, double-click the slot containing the card.

The Card Settings NET-8 Network Parameters dialog box opens.

The Net-2/Net-4/Net-8 Network Interface module supports 2/4/8 T1-CAS spans depending on the card model. Any of these spans may be set as the “master clock,” which synchronizes the system clock to the network clock, or “backup clock, which is used if the master clock fails. Only the spans being used are configured. The same Network Service may be used for all the spans. In such a case, different circuit IDs must b e

defined for each span in the Network Service.

• It is not possible to mix an ISDN and a T1-C AS Netw ork Servi ce on the same

Net-2/Net-4/Net-8 Network Interface module. If an ISDN and a T1-CAS Network Service are mixed on the same Network card an error message is displayed.

• Net-T1 module does not support a T1-CAS Network Service.

3. To assign a Circuit ID to the appropriate span:

a. In the Span “n” box, clear the Null Configuration check box to

enable the span.

b. In the Circuit ID box, enter the circuit ID as defined in the Network

Service–Spans and Phones dialog box. According to the selected Circuit ID, the Network Service is assigned to the network card.

Each span can be assigned a different Network Service.

c. Click Apply.

The name of the network service appears in the Service Name box.

4. Click OK.

To configure a Net-2/Net-4/Net-8 span as primary or backup clock:
