Re: W914552s SSL76 E1 Spec
Thanks. Well, as search IC product code in google engine it match found as a product developed by Intel. Matching IC description type with the card IC, unfortunately as not available Intel E1 transceiver datasheet it couldn't check beforehand coincidences. These types o card mainly are development in China. 1.- Unfortunately the card not have manufactured product information as it’s generic TDM card. 2. - E1 transceiver IC code it indicated as Intel IC manufactured.

Hi, thanks. The product in question it refers to a hardware category of TDM Telephony interface cards (E1/PRI TDM, FXO Foreign eXchange Office and FXS Foreign Exchange Station) mainly used in Asterisk open source. My question it refers to china manufactured E1 TDM card which use E1 IC transceiver W914552S SLL76. This IC transceiver connect 30 digital voice channels in frames of 24 or 30 voice channels, plus tow channels one for synchronization and another for voice signaling, multiplexed in a 2 Mbits frame, the process of Multiplexing and coding is based on standards G703, 704, etc. Tks.3.2KViews0likes0Comments
