RLH iMux System
MODULAR 16x1 VOICE AND DATA
MULTIPLEXED OVER FIBER OPTICS
The iMux is a powerful fiber optic modular multiplexer capable of
providing up to 16 channels of E1, T1, V.35 (RS530), X.21, RS232,
2/4 wire analog data/SCADA/E&M and analog phone FXO/FXS
services, plus four built-in 10/100M Ethernet ports, over a single fiber.
These services are supplied by iMux 4x1 modules that plug into the
back of the unit. Each module has 4 ports, and up to 4 modules may
be installed in any combination. Spares or add-on modules may be
ordered separately and installed by the end user, and may be used
with leased lines to build up private networks, private telephone
networks (by interconnecting PBX's) or access the internet or a
partner network (extranet). A typical complete system comprises of
one FXO and one FXS module, or use an FXS unit at each end for
ringdown operation where direct connection to phones on both ends
of the system is desired.
The optical modules are installed into the front of the unit. Both dual
fiber and single bi-directional fiber (WDM) optical modules are
available, and up to 2 optical modules may be installed, providing 1+1
hot-swappable optical protection and making the best use of fiber
availability.
The iMux may be managed through SNMP, web Interface, VT100 craft
port or LCD/menu keys on the front panel. It also has an external
alarm port for alarm input monitor purposes, and an alarm port with
four alarm contacts. The system provides local/remote loopback
functions for optical and E1 interfaces, and is ideal for network testing
and maintenance.
The iMux takes up 1RU and comes complete with EIA19” and 23”
rack ears, or it may be used on a desktop or shelf.
