FMUX/SAT Multiplexer
© 2006 Cronyx
Section 1. Introduction
1.1. Purpose
FMUX/SAT is a multiplexer with variable frame structure, which allows transmitting up
to four E1 channels over synchronous link equipment with codirectional interface, such
as satellite modem with V.35 DCE interface (see Section "1.3. Connection Diagram").
Note
Hereinafter term "E1" is used to denote data transmission channel with interface
complying with ITU-T G.703 standard for transmitting data with bit rate of 2,048
kbit/s in both framed mode in accordance with ITU-T G.704 standard, and unframed
(transparent) mode.
1.2. Features
•
Data transmission from one to four E1 ports over synchronous link equipment
with codirectional interface.
Link bit rate depends on the number of Е1 ports used:
