 Introduction
HPOM-8E1-4ETH Optical multiplexer is 8*E1 G.703 + 4 Ethernet 10/100BaseT fiber multiplexer with logical
bandwidth control, QoS, and dot1Q VLAN's which allows effective transmission of those protocols over fiber
optical cable over distances more than 120 km.

UPCOM HPOM-8E1-4ETH can provide up to 8E1 interfaces and 4 Fast Ethernet interface. The Ethernet
interface can be operated in 10M/100M, half duplex or full duplex mode by either auto-negotiation or manual
setting.

HPOM-8E1-4ETH is a fiber media transport for 8E1 + 4*10/100BaseT transmission. The BNC model provides
unbalanced 75 Ohm coaxial connections while the RJ-48C model provides balanced 120 Ohm connections
over twisted pair wiring, it provides an order-wire for which a standard telephone can be used.

HPOM-8E1-4ETH provides a user RS232 transparent data link with a RJ45 connector which possesses
complete operation monitoring function. Those indicators include Loss of optical signal, LOF, 10-3, 10-6 bit
error rate, Loss of each E1 tributary signal and Ethernet status. Since some overhead bytes are taken as
monitoring channel, all alarm and status of Remote can be display locally.

 HPOM-8E1-4ETH provides RS232 interface for Network Management. Supported by GUI NMS utility, users
can observe the status of Local and Remote, as well as other alarm information unable to be displayed by
LEDs in the front panel. Also, with NMS software, user can make certain E1 loop back for testing purpose, 4 *
10/100 Ethernet ports support intelligent Layer 2 switch features, such as QoS, dot1Q and port based VLAN's,
flow control per port with steps n*32 Kbit/s and more.
