Section 1. Introduction
•
Built-in power supply unit for mains or battery
E1 port data are transmitted independently, the clock frequency of each port does not
depend on that of the other ports.
The device may be managed over the RS-232 interface using ASCII terminal (console),
or over SNMP protocol over auxiliary Ethernet 10BaseT port.
Loop and built-in BER tester management is performed from the console. BER tester
allows measuring error rate in the link path. The measurements are performed using
fixed or pseudo-random code in accordance with ITU-
T
О.151 standard (the pattern
length is 2
15
- 1 = 32,767 bits).
A remote login ability is provided for testing remote device ports from local console,
when there is no personnel at the other end of the link. Commands to remote device are
sent over monitoring channel, organized in the link path.
The FMUX/SAT is equipped with LED indicators, which show state of ports and link
equipment, loops enabled states, and testing modes.
The device is equipped with an emergency alarm relay, the "dry" contacts of which may
switch on external device to call the operations personnel (in accordance with ITU-
T
G.742 Standard, s. 10).
The multiplexer has capability of firmware upgrades.
1.3. Order Code
The FMUX/SAT multiplexer is manufactured
as a device in 1U high metal enclosure, for
mounting in a 19” rack
. The multiplexer is equipped with auxiliary Ethernet 10Base-T
port for management over SNMP protocol.
The power supply device for 176 - 264 VAC mains has the following order code:
FMUX/S
–
4E1
–
SAT
–
SNMP
–
AC
The device may be ordered with 36 – 72 VDC power supply. In this case "–
AC
" suffix
in the order code must be replaced with "–
DC
".
