Introduction 1.1. Application The FMUX/S-4E1-E2 is a 4 channel multiplexer, allowing to transmit up to four E1 channels over a E2 link. Each of the E1 channels is transmitted independently. The synchronization frequency of each link is non dependent on the synchronization frequencies of the other links. -
