25 MB Data Buffer with TCP/IP interface


BUENO

Contec Bueno buffer is used in single and multisite installations where full call data security and centralized call data collection system over LAN/WAN is needed. The buffer, attached locally to the PBX collects CDR data from RS232 port or IP port. Transfer of data from buffer to the Processing Centre is done over standard Ethernet LAN/WAN.

Advantages of BUENO buffer:

  • Fast data transmission – built in 10base-T network interface of with TCP/IP protocol, allows for fast and safe data transmission from buffer to processing computer
  • Versatility – collects CDT data from all types of telephone exchanges, both modern with IP port and traditional with RS232 port
  • Safety and confidentiality of data – industrial design, non volatile data memory, secured data access and passwords, transmission protocols and alarms guarantee safety of collection, storage, and transmission of data
  • Alarm detection - buffer detects various threats to data collection process and automatically sends warnings to the security center as well as local administrator.
  • Ease of use – buffer can be preset before shipping. When connected to RS232 port it automatically adjusts its transmission parameters. Full remote setup possible through a custom configuration program or by standard TFTP client tool.

BUENO Buffer Specification

 

Memory

· Nonvolatile Flash memory,

· 25MB data capacity: - approx. 500 000 standard call records. Higher capacity available on request

· Data stored in FIFO revolving buffer, new data replaces oldest data.

LAN Interface

· used as a data port to collect data from PBX and send to processing computer through LAN/WAN

· Ethernet 10T standard port

· Operates with fixed IP address or automatically assigned (DHCP)

· Protocols: TCP/IP, FTPT, TFTP

Collecting CDR (Call Data Records) Data from PBXs

 

Port RS232 – exchanges with serial port

· Automatic or manual adjustment to PBX transmission sending parameters

· 1200-57600 b/s

· Compatibility with full RS232 flow control signals standard

· Full RTS/CTS flow control

· Protocols – optional ability to implement individual protocols (on request)


Port TCP/IP – exchanges with IP port

· Retrieving CDR data via TCP/IP as client or server

· Protocols – optional ability to implement individual PBX type protocols (on request)

Data transfer to the processing center

Port TCP/IP

· Buffer works as a TFTP server

· Transmission of “new” data or the entire buffer data memory

 

Data Confidentiality

· Data encoding during transmission

· System of user rights and access codes

· Access authorized through passwords and logging with NAS (Radius) protocol

· Access to buffer only by specified network users

 

Data Safety

 

· Transmission protocols

· Small internal UPS to ensure safe data write into Flash memory during power failure

· Event logs

Alarms

Alarm situations detected:

· Connection with the PBX lost

· No new CDR data in specified time

· Data errors at entry port

· Memory full warning threshold reached

· Alarm string in CDR data detected

· External alarm received (2 low voltage inputs)

Reaction to alarm:

· Alarm message (IP package, e-mail, SMS)

· Closing contacts of internal relay (single low voltage output)

· SNMP message

· SysLog messageInternal buzzer

Remote Maintenance

· Remote access from any computer in the network

· Alarm configuration

· Authorization configuration

· Reading of logs

· Service reading of the entire memory

· Redefining buffer parameters

Power Supply

· 220VAC/12 VDC external converter (preferably form external UPS)

· from PBX’s battery with optional built-in coverter 36..72 VDC/12DC with galvanic separation

Dimensions

· 170 x 190 x 44 mm

· Weight 0.5 kg

 

With the buffer we provide BuConf program used to configure and service the buffer, it may also be used for data transmission from single location.

 

Technical modifications may be introduced at any time
