16. Buffer Functions (Polling)
The procedures in this section are used to retrieve data that has been
collected from the PBX. The VIP offers four different polling methods:
1. Menu Driven: The VIP is contacted via modem or Console Port, and
the Buffer Functions Menu is used to release data.
2. Command Driven: The VIP is contacted via modem or Console Port,
and ^Bxx commands are entered at the command prompt to
release data.
3. FTP Push: The VIP automatically downloads records via TCP/IP
connection to your FTP server.
4. FTP Server: an FTP client program is used to retrieve stored data
from the VIP unit on demand. In this case, the VIP functions exactly
like a standard FTP server.
16.1. Memory Partitions and Shared Data
After data is collected from the PBX, it is stored in the VIP's memory.
Stored data can be retrieved via the Console Port, Modem Port, or Network
Port. In order to prevent conflicts when two ports attempt to access the
same data, partitions are set to temporarily grant "ownership" of a specific
type of data to a specific port. For example, the Console Port may own all
data received via PBX Port B, or the Modem Port may own all records that
matched Alarm Filter 1.
When a partition is set for a specific command port, other command
ports will not be able to access the partitioned data. For example, if the
Console Port partition is set to include data received via PBX Port A, then
the Modem Port will not be able to access this data until the partition is
released.
These partitions also simplify the process of clearing data after it has been
read. After downloading data from your command port partition, command
^B25 or the Item 5 in the Buffer Functions menu can be used to clear the
partition. Note that records that are received after the partition is set will
not be erased. Once a partition is set, it will remain in effect until the
partition owner exits from command mode, or invokes one of the partition
release commands.
