K1E1 – 300E

single E1 network interface board


The K1E1-300E was developed like the K2E1-600E, to meet the needs of CTI applications which require advanced voice resources.
Voice resources are available for all 30 channels simultaneously and are executed by the board digital signal processor (DSP), without using the host’s processor. ,
Khomp offers the K1E1-300E in two models; PCI and PCI-Express. The PCI-Express model has DMA technology, which reduces CPU consumption, allowing increased density per server.
Examples of applications are audible IVR, telemarketing, help desk, customer service, voice mail, call center, conference machine, Soft PBX, among many others.
