5.3.8.4 UCV2D motherboard
The basic cabinet contains 1 or 2 (duplex mode) main UCV2D cards, each with:
•
1 control unit
•
3 Ethernet 10/100 BASE TX accesses
•
1 32-trunk matrix with dynamic addressing
•
1 voice mail system with 8 access points
•
1 Compact Flash Card (software of the Gateway and terminals, configuration’s data…); the
capacity of the COMPACT flash allows a new software release, a new firmware release of the
IP/SIP terminals to be downloaded and the buffer function (for tickets and billing) to be
integrated and the pictures storage. From version R5.1C, the memory size is 2Go. A new 4Go
compact Flash card is available with R5.4.
•
8 3-way conference circuits
•
4 alarm loop inputs and 4 alarm loop outputs
•
1 HDLC controller for setting up data communication in a B channel
•
1 integrated answering service
This card exists in RJ45 connection format.
In simplex mode, the UCV2D card provides the same functions as the AXL UCV2L card (see also
4.3.4.4).
The UCV2D card has the following interfaces:
•
one console for testing and debugging the card when it is in a “passive” state (1 DB9 Debug
connector)
•
Ethernet network: 2 Ethernet 10/100 BASE TX access (LAN RJ45 connector)
•
interface with RUCV card of an expansion cabinet, located on the back of the cabinet
•
USB connector for configuration’s backup and restore
The IUCV2D card has the following interfaces:
•
one operating and debugging console for the active card (1 DB9 console connector)
•
a serial printer (RJ45 socket) (printer port not active from R5.1)
•
an external music source (RJ45 socket)
•
a general bell
•
alarm inputs (4)
The i-button for enabling the software functions is located on the IUCV2D motherboard.
Power supply of the UCV2D card:
The UCV2D card receives the following on the backpanel connector (J1):
•
+5V input for its internal circuits
•
+12V input generally to supply power to external equipment
•
- 48V input for analogue and digital terminals
•
70V AC input for the ringing current of analogue terminals
The UCV2D card includes a 2.4V and 80mAh NiMH battery responsible for:
•
storing the contents of the internal memory for about 2 months
•
backing up power supply for the internal clock
•
The battery is soldered onto the circuit and is not interchangeable; when installing the system,
charge the battery for 12 hours
