| Hicom is the old model of system. The programming and end user use is very similar between the HiCom and HiPath systems, a good amount of hardware (cards, phones, etc.) is also backward compatable between the HiPath and HiCom systems, but not all hardware is the same or compatible by any means. But, in essence, no the HiCom is not the same thing as a HiPath system. HiPath 3000 is only the name of a family of systems, there is no such thing as a HiPath 3000 system (they are 3300/3350, 3500/3550, 3700/3750 and 3800). The cabinets are different and the HiPath generally use the OptiPoint 500 phones, not Optiset E phones, though a HiCom and HiPath can support both phones if it is equipped with the right cards, but the HiCom was mainly designed with OptiSet E phones in mind. A HiCom cannot be upgraded to a HiPath by software or firmware downloads, if that helps to clarify. As for cards...make absolutly sure you get the correct version for your system . There are many versions of HG1500 and other cards that will not work with on a system running a different version than the card. Steve |
