 shows Optimux-34 a fan out of E1 channels on a remote site 
extension. The Optimux-34 unit is connected to a fiber optic modem (FOM-E3) 
with an E3 interface, to a distance of up to 110 km.

Features 
A combination of 16 E1 ports and 10/100BaseT USER Ethernet and V.35 interface 
can be combined into a single E3 uplink. It integrates multiple E1 links and is 
suitable for E3 transmission over coax or various modes of fiber optic 
transmission. 
Optimux-34 features link redundancy (an optional backup link), which enables 
coupling of fiber optics and coax modules to the link and has an optional modular 
hot-swappable redundant power supply and a second E3 link for automatic 
backup. It also has an optional alarm port. It can accommodate up to two (one 
redundant power supply in case of power failure or disconnection) built-in 
universal power supplies for a wide range of power sources. 
The device offers user-selectable bandwidth allocation between E1 and USER 
Ethernet ports. User Ethernet is activated by means of a license. 
The V.35 interface is available on both the 1U and 2U devices. The V.35, when 
selected, is fixed on channel 16 and has a rate fixed at E1. 
The 2U box supports unbalanced E1 only on the tributaries.
