The PortStore with PBX
A typical application of the PortStore and PortStore2 devices is storing a CDR/SMDR from PBX serial port, which can be then accesed over intranet or Internet network. You can also store tarification (call accounting) data to the PBX using the RS-232 interface.
 Branch phone exchanges (PBX) typically use the serial RS232c (or RS-232) interface for exchange of billing data. Data format depends on the PBX type, but mostly the exchange can be connected to a printer or a PC with application software that loads ongoing call accounting data. In this application, it is cost-effective to replace the remote PC with a dedicated remote buffer box, which stores call data records from the phone exchange when the PC is turned off or busy. The buffer can be connected to the phone exchange using the RS-232 or RS-485 interface.
Let's take an example of a phone switch located in the basement of a building. The installation of more cables, converters or flash memory for transmitting data represents extra cost. The data recorder eliminates these extra costs by simply connecting the RS-232 port of the switch to the buffer's RS-232 serial port. The Ethernet interface of the buffer box is then connected to the intranet. So if you already have the Ethernet network wired in the building, the buffer price is the only cost.
The billing data is stored in 2,048 kB flash buffer in the device. Using space compression, the data of up to 20,000 / 80,000 phone calls can be stored. The data collected in the internal buffer is accessible over the intranet using TCP/IP interfaced to the call accounting application.
Whenever the PortStore “buffer” is about 75% full, it sends an email to the person responsible for running the accounting application. If the responsible person is not available (for example on vacation), the “Buffer” sends an email to the second listed address to alert when 10 % of the capacity remains.
The PortStore2 data recorder does not send an email but starts to attemp to send data by TCP connection to predefined IP addres in "RAW format" - TCP Client/Server mode.
 A branch telephone exchange (PBX) is located in the basement of a building. The nearest PC could be up to 5 to15 meters (16.4 to 49.2 feets) away, which is the maximum recommended distance for RS232. However, Ethernet is installed because of the existence of a network router or switch for the local intranet.- The worker evaluating phone bills, other account information or telemanegement over an intranet is located in another building in the same area.
- Data can be safely exchanged all over the various points on the intranet/Internet using TEA encryption. The PortStore and PortStore2 buffers are independent net devices, which do not require any other support hardware.

FAQ & Support
Q: What is the difference between PortStore and PortStore2 devices?
A: It is basically the same device with two different firmwares. The basic differences are:
- PortStore supports only TCP Server + SMTP email notify when data buffer overflow
- PortStore2 supports TCP Server or TCP Client/Server modes, no SMTP email supported
Q: Which SW companies use PortStore/PortStore2 and what are their experiences?
A: About 20 SW companies are using the Portstore/PortStore2 device together with a PBX. We can send you the list upon request via email.
Q: How are the stored data protected?
A: The security is very important to us. Every device can use an IP filter.
For increasing the security of data transfer in TCP mode it's possible to authorize both sides on establishing any TCP/IP connection via TEA 128 algorithm with symmetric signature. The configured password of both sides then will not go through the network.
Q: Why are there 2 email addresses for buffer overflow alerts?
A: It's a practical fallback in cases where the responsible person is out of the office for varying periods of time. It's very useful to set a second email address to reception or to a general email so overflows are not overlooked.
Q: We want to develop our own software, are there any examples available?
A: Yes, check our Support & Download page for many examples for Borland C++ and Delphi (as well as Visual Basic , JAVA and PHP ). We have released a software for reading the buffered data - PS Eye.
