12. ANNEX D: Remote Data Centre (RDC) Operation
The RDC purchase-time option allows the transfer data between the converter
and a remote computer located at a remote management centre. Data is
transferred over a local or wide area network using the FTP protocol.
Up to 4 different Remote Data Centres can be configured and each report can be
configured to use two RDC’s (one as the primary RDC and the other as the
backup RDC). This ensures continuity of service in case the connection to the
primary RDC fails.
The RDC option uses the FTP file transfer mechanism to exchange data with the
remote site, the remote site requires only an industry standard FTP server to
handle the file transfer and does not require any proprietary software on the
remote computer. The converter ’logs on’ to the remote computer using a user-
configured user name and password.
Two categories of report are made to the RDC, Continuous Records and Periodic
Reports. In each case there are several report types as detailed below.
The data transferred for each report type is stored in a different directory on the
remote system using a new file for each day’s information. The directory name is
user configurable.
12.1 Continuous Records
Continuous records provide the capability to transfer records to an RDC on a
continuous basis in near real time. The minimum number of records collected prior
to transfer and the maximum time interval before the transfer is attempted are
configured by the user. This allows the user complete control over when records
are transferred to the remote data centre, within system limits.
Continuous recording can be configured to support the per call transfer of billing
records and call failure records to an RDC and the occurrence and clearing of
alarms to an RDC. The records are formatted as a comma separated variable
(CSV) text file.
12.1.1 Billing Records
Billing records are generated (if enabled) for all calls that have reached the
answered state. Billing records are enabled on an outgoing route basis by
associating the OGR with the configured Continuous Record.
Should communication with the primary RDC for the Continuous Record fail then
the converter will automatically transfer those records to the secondary RDC. In
the event that both the primary and secondary RDCs fail, billing records are stored
locally on the hard disk until the one of the RDCs recover. The records saved on
the hard disk are then automatically transferred to the recovered RDC.
12.1.2 Call Failure Records
Call failure records are sent on a per call basis for calls that release prior to
reaching the answered state. Call failure records can be enabled selectively on a
point of origin basis.
