 The MM04 product line is a 4 port E1 or T1 
multiplexer/demultiplexer that transmits over a fiber optic link. The products 
are standalone (1U), 19" rack mountable (half-size devices). The optical fiber 
interface is available in a number of standard fiber connections and has 
optional redundant optical connections. The chassis is available with universal 
AC power supply (100-240v) or DC power supply (36-60v) and and in option of 
redundant power supply.
 
 MM04 devices support four (4) link interfaces 
and are available for E1 or T1 configurations with connections for RJ-48 (E1/T1 
balanced). In long haul mode the interfaces possess usable receive sensitivity 
of 0 dB to -43 dB for E1 and 0 dB to -36 dB for T1 which allow the device to 
operate with 0.63 mm (22AWG) cables at distances up to 2.5 km (E1) and 6000 feet 
(T1).
 
 Each E1/T1 port is designed to meet regulatory compliant solutions 
such as for circuit protection against surges and AC lightning, which is 
essential for long haul E1/T1 lines.
 
 A robust frame-acquisition and frame 
holding algorithm minimizes frame slippage and resynchronization.
