Use a 'Y' cable for independent processing of the same data source


Sometimes you need your data to be in two places at the same time. That was the scenario for a bank IT manager who needed to generate two completely independent reports from the same ACD (PBX internal phone extension data). The bank accomplished this simply by using an inexpensive Y cable that duplicates the data and allows each data set to feed into independent ports of the Asentria Data-Link device.


Each Data-Link serial port collects data in an associated memory storage file. You can set up the data collection and data transfer options independently for each serial port. So, once data is duplicated, each set of data can be managed according to your specialized site needs.


In this bank’s application, the ACD enters Data-Link serial port I/O #1 and flows uninterrupted out serial port I/O #2. The Y cable adapter is attached to the I/O #2 output. The ACD stream enters the Y cable adapter as one stream, but exits the adapter in two equal streams. One stream flows directly to the bank’s call accounting software on a PC, the second stream is diverted back into the Data-Link via I/O #3 where the ACD is stored in flash memory storage File3. The File3 data is then transferred automatically on a timed cycle using FTP push to a different ACD processing software on the LAN/ WAN. With this configuration the bank can process the same data in two completely independent processes, and the data is protected from loss if the PC crashes or the LAN/WAN connection goes down.


Data-Link users should consider a Y cable adapter any time you need a duplicate set of data. With the Data-Link unit’s ability to manage each data set independently, users are finding creative ways to utilize the functionality. Some IT managers are creating a “backup” data set to fulfill requirements for “redundancy” in their systems. They send the backup to a separate Data-Link storage file that retains the data by either having the data “wrap” at a specified memory allocation (retaining the newest records), or transferring the data to a separate location via modem, modem/PPP, FTP or real-time transfers.

  1. ACD leaves PBX and enters Data-Link serial port 1.
  2. ACD leaves Data-Link serial port 2 uninterrupted. The data stream is duplicated by a Y cable adapter (indicated in red). One data set is transferred to the call acounting software. The other set is diverted back into the Data-Link serial port 3 where it is stored in memory file 3.
  3. Data-Link FTP pushes the data in memory file 3 over the network to ACD processing software.
