4.3 UCV-D card
4.3.1 Functional description
The UCV-D card provides the following functions described in Section 3.8.1:
• Data and voice switching
• Duplex logic and start
• Signal processing
• Voice mail server
• Defence (management of interface card statuses)
• Synchronisation
• Management of interface card commands.
It also offers the following functions:
• Interfacing with:
- an operating console via Ethernet access
- the RUCV card of an expansion cabinet
• Supervision of expansion cabinets:
The power on state of an expansion cabinet is detected by recognising a
synchronisation pattern. The UCV-D card can command a general "Reset" of the
expansion cabinets, provided they are synchronised.
• Power supply: the UCT-D card receives the following on the back plane connector
(J1):
- a +5 V power supply voltage used for the operation of its internal circuits,
- +12 V power supply used in operating the microcontroller.
The card has a CR2450 type battery for:
- retaining the status of the Duplex logic
- backing up power supply for the time stamp.
The battery is installed on the circuit card and is interchangeable. The service life of
this battery is minimum 5 years, and 10 years in a system that is permanently
powered up.
• UCV-D has a Flash Disk on the IDE bus, comprising a Compact Flash card fitted on a
CF Socket type II. The CF card is not accessible on the front panel.
• The VMAIL function is directly on the CPU card. A quota of compact flash disk space is
assigned to this function to store messages and prompts.
Daughter cards
• The UCV-D card can be fitted with two EIP daughter cards for managing VoIP
communications. These two daughter cards have 8/32 channels each for signal
processing.
Note: The UCV-D card is compatible with the ROHS Directive.
