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.

Hereinafter the 'E1' term is used to denote a data transmission channel with an interface
complying with the ITU-T G.703 standard for transmitting data with a rated bit rate of
2,048 kbit/s in both framed mode in accordance with the ITU-T G.704 (or PCM-30)
standard, and unframed mode.
