Ping Ping is used to see if the MCU is able to reach a specific IP-address, using a mechanism in IP called ICMP. If the MCU is unable to register to its gatekeeper, or if it is unable to dial a specific endpoint, one can use ping to see if there is at least an IP-route to the gatekeeper or to the endpoint.
• If the MCU experiences packet loss from an endpoint, it will ask the endpoint to handle packet loss. This requires Intelligent Packet Loss Recovery functionality on the endpoint.
Yellow alarm or Remote Alarm Indicator (RAI) means that the MCU is receiving framing info, but in this framing info the other side tells the MCU that it is not reading the MCU’s transmitted framing info. Typically, this may be a broken connector in the TX part of the MCU PRI cable.
If a CSU loses framing/sync from the network (example: a bad cable B), it shall no longer send valid framing out on cable A towards the MCU. Instead it transmits "Blue Alarm". Seen from the MCU receiving blue alarm, this means that the network on the far side of the CSU is unavailable.
(Users will be prevented from setting up calls that exceeds this limit). Example of call weight calculation: If the MCU has made 6 calls at 768 kbps, 4 calls at 384 kbps, and 4 encrypted calls at 192 kbps the calculation will be: 6x62 + 4x46 + 4x60 = 796.
*) Limited by the maximum capacity 7680 kbps, see rule II a) above. **) Limited by the maximum capacity 5888 kbps, see rule II b) above 4.1.8 Dial Profiles The TANDBERG MCU can be programmed to use different Dial Profiles. Dial Profile consists of a name and a prefix. Example: If 0 (zero) is needed to call outside a location, create a prefix called ‘external’...
- If encryption mode is set to Auto, the MCU accepts both AES and DES encryption. - The MCU administrator can also force the MCU to require only e.g. AES encryption. In this case, all participants must have AES in order to join the conference.
I.e. The administrator may decide which site’s video shall be broadcasted to all participants. Terminal Site naming: The TANDBERG MCU also supports site naming (on ISDN and IP). Thus, if the connected sites also support site naming, a transparent line of the broadcaster’s site name will be displayed (for approx.
Note: Using DTMF tones is the only way to enter a protected meeting from a site connecting on IP network. If password is correct, the MCU will join the system to the conference; if not correct the system will not be connected.
The following is a description of how the ISDN channels are set up. Incoming & Outgoing MCU calls: Normally the MCU will set up only 1 channel from PRI 1 and build up the channels starting from the 'bottom' of the last PRI in use.

FTP-client bundled with the Windows operating system), it is possible to upload the new software release to the MCU. The software file is in binary format in order to decrease upload time. All settings of the MCU will be restored after a software upgrade.
The TANDBERG MCU supports HTTPS in order to ensure secure transmission of the information displayed on the administrator’s PC. I.e. a secure connection between any Web browser and the MCU (the MCU web server) will be established if the HTTPS service on the MCU is enabled. HTTPS allows for password exchange which is especially important.
There is no router inside the system that can route between the ISDN side and the IP side of the TANDBERG system. This means it is not possible to get access to the Ethernet port via an ISDN conference. However, if wanted the following services may be disabled/enabled (with API commands): •...
