Adapter Tau-PCI/32 represents the multiplexer-crossconnector with two E1 ports and 32 built-in HDLC-controllers. The basic applicability of adapter Tau-PCI/32 - construction of networks of data transmission on the basis of E1 channels, and also for creation of the specialized equipment of processing of E1 streams (a telephony, signaling).

Currently available models are listed in Prices. Please, contact technical support if you are unsure which model to choose.
