HUB Components
Cards installed to the PCI back plane will include 1 CPU card with a 64 meg or higher compact flash HD and 32 meg DIMM module, at least 1 PRI/T1(E1) card, and at least 1 Quad-Link card. Internally there will be a ribbon cable connecting the PRI card to all the Quad Link cards. This is for the digital audio to and from the PRI card(s) to the studios.
See the manual for typical installation positions of the cards. Fully populated in the correct slots the 2101 can support 4 PRI lines (2 dual PRI/T1 cards) and 32 studios (8 Quad-Link cards)
The Hub is running a Windows NT embedded system O/S. On the top of it, our Win32 software application is running. It is automatically started up as soon as WinNT is booted up. To execute this a small application called HubSpawn is run at startup. This application’s function is to restart the 2101 application and Web Browser should they ever be stopped manually or crash.
The keyboard and monitor plugs on the back of the Hub are only used for configuration of the BIOS screen of the CPU card as needed. Because of the small size of the HD, no graphical, mouse or keyboard drivers or interfaces are installed and are not used for normal operation of the 2101 system.
Resetting the Hub
- Software Restart. Within the Web Page for the Software Update there is an option to REBOOT the application. This option only restarts the 2101 application. It does NOT restart the NT embedded OS. This is the first preferred method for restarting the 2101 Application.
- The RESET button on the front panel resets the PC motherboard. This option should be done when making system changes such as the IP address change to the hub. This option is also a “last resort “ option should the hub become stuck in a weird state.
- On the small hub chassis, no power on/off switch. To do a HARDWARE reboot, unplug/plug back the AC. On the large chassis there is a power switch on the left side.
During configuration and/or troubleshooting you will likely need to reboot the 2101 system. For changes to the 2101 configuration, such as telco changes, restarting only the 2101 application is recommended. Rebooting the 2101 computer mainframe may be required for a complete reset of the system based on other issues you encounter.
One front LED indicates that the Hub is powered on. Some LED’s on the back of each additional card indicate the current states of these. (see details in manual)
- On the small chassis the RED button on the back of the Power Supply stops the alarm (beep) occurring by a faulty Power Supply. On the large chassis there is a button inside the front cover.
See Part II of the 2101 User’s manual for more information.
Studio I/O Components
- SIMM 4MB (2 banks of 2 MB each)
- 10 Mbps network Ethernet Port
- T-link card installed, has one RJ 45 port w/LED status indicator.
- One to two Desktop Director (DD) boards: each of them has 2 ports. On each port, 2 DD’s can be plugged in, using a splitter. A total of 8 DD’s can be plugged into one Studio unit (or 6 plus one Ext. Hybrid). A total of two DD’s or 2 Extended DD’s per Studio can be plugged in DIRECTLY to the I/O without any external power supply.
- Motherboard
- Front Panel
Resetting the Studio unit
- HARDWARE RESET done by the Power button on the back
- SOFTWARE RESET done by the internal menu (SYSTEM / SOFTWARE UPDATE / REBOOT SYSTEM)
Note: There is no difference between a hardware reset and software reset. Each will accomplish the same result, resetting of the unit.
An LED on the back of the T-Link board indicates the state of the audio line from the 2101 Hub on the Studio unit side. LED should be extinguished when operating properly.
Extended Hybrid Components
- SIMM 4MB (2 banks of 2 MB each)
- 10 Mbps network Ethernet port
- One S/U ISDN card installed.
- Motherboard
- Front Panel
Resetting the Studio unit
- HARDWARE RESET done by the Power button on the back
- SOFTWARE RESET done by the internal menu (SYSTEM / SOFTWARE UPDATE / REBOOT SYSTEM)
Note: There is no difference between a hardware reset and software reset. Each will accomplish the same result, resetting of the unit.
There are NO Desktop Director cards installed to the Extended Hybrid unit.
See Part IV of the 2101 User’s manual for more information.
Desktop/Console Director
The Desktop Director (DD) has its own integrated micro-controller. It exists in three versions:
- 12 lines
- 24 lines (Extended DD)
- 12 lines Console Director (ready to be mounted in a mixing console)
Basically, this is the same hardware. To change the software in it, an EPROM has to be changed. Special software is available for the Console Director used to control lines 13-24 for use when a 24 line show is loaded in the Studio I/O.
One of our newer products called the Call Controller also can be used for 12 line control. This product does NOT have a handset but has a separate port for an analog POTS extension for customers to supply their own phone for use.
The DD or Call Controller is connected to the Studio unit by a single cat 5 cable with power included. The ISDN protocol on this cable is the following: 2 B-channels + 1 D-channel
The B-channel is a 64 Kbps stream only reserved for audio.
The D-channel is a 16 Kbps stream only reserved for data packets. It is connected to a bus called the HDLC bus in the Studio unit.
All units are powered by –48vdc on Pins 7&8 of the Cat 5 cable with a maximum length of cable at 250ft or 75 meters. For installations that must have DD’s located much further will require external PSU’s. A single DD on an external PSU can be located up to 2300 ft or 700 meters from the interface.
The Studio Interface can power up to two DD’s or two Extended DD’s directly from one installed DD card. Additional DD’s and/or an extended hybrid may require a second DD card installed to the interface. DD’s may also require external PSU’s. When connecting more than 2 DD’s to the Interface an external PSU kit will be required. The kit should include a floor wart PSU and a bridging RJ45 Y cable. The external PSU can power two 12 line DD’s OR one 24 line Extended DD. Configurations for 2 DD’s connected to the same data line will require the DD closest to the Interface to have it’s termination resistors removed. For more details on configuring multiple DD’s to an interface see CSB #31102k titled “Wiring Configurations for the Telos Desktop Director” and see Part IV of the manual on DD wiring.
Resetting the Director
There is no power button on the Directors or a software reboot option in the menus. Unplugging/plugging the Cat 5 cable in the back of the Directors will power cycle the units and cause them to reboot.
Warning: If the DD is powered by an external power supply, unplug the cable between the P/S and Director to reboot. Unplugging the cable between the Studio I/O and the external p/s will not cause the Director to reboot.
See Part V of the 2101 User’s manual for more information.
