FMUX1001 Modularized 16E1/T1 + 4x GbE Fibre Managed Multiplexer (E1/T1, Data, Voice, Ethernet)

FMUX1001 GbE Fibre Managed Multiplexer

The FMUX1001 is a 1U, 19" rack mountable, PDH fibre optic multiplexer that transmits up to 16 channels plus a 10/100/1000Base-T Fast Ethernet channel over a single fibre optic link. The FMUX1001 chassis suppats redundant power and hot swappable design. The AC supplies operate from 90~260VAC while DC supplies operate from 36~72VDC or 20~60VDC. From the rear of the chassis, one to four hot swappable quad E1 or T1 line cards, serial data communications (V.35, X.21, RS-530) or  FXO/FXS voice cards are supported. The standard FMUX1001 configuration may be viewed or set via the front panel LCD/menu keys, serial VT-100 terminal connection, Telnet, web HTTP or SNMP.
