Introduction

UPOM 16E1 to 4-port Ethernet converter is an Ethernet extension device that use PDH, SDH or other microwaves to carry Ethernet data, allowing users to transfer Ethernet data into E1 frame format through the existing TDM (E1) links and then re-convert E1 back to Ethernet data at the remote terminal.

HPC-16E1-4ETH, 16E1 to 4 Ethernet converter support GFP-F, VC (Virtual Concatenation), LCAS (Link Capacity Adjustment Scheme) and professional GUI (Graphical User Interface) NMS (Network Management System).

HPC-16E1-4ETH is an IP over TDM converter, which supports the conversion from MAC frames to 1–16 E1 lines. The maximum bit rate is 32 Mbps (16E1 lines). it can meet various requirements and can be customized to meet your network needs. It not only provides alarms and status of the E1 line and Ethernet interface together with advanced management functions, such as throughput statistic of the Ethernet, but also supports the Unification Network Management via SNMP and GUI. It conforms to international standards and can be used with third-party device that follow the same protocol.

4-port 100M Ethernet interfaces operate in full-duplex or half duplex with flow control, the mode can be set or monitored by management software. The device also has multi-port bridging capability to handle up to 5 bridge ports. The Bridge supports two modes of operation: VLAN-Enable and VLAN-Disable modes. In VLAN-Enable mode, it creates sub-groups of bridge ports within the bridge. Each sub-group is associated with a unique VLAN ID (VID). Frames containing a VID can only be forwarded between bridge ports which are members of the specific VLAN, enabling a total separation between different VLAN users within the same bridge; In VLAN-Disable mode, the bridge forward frames ignoring the VID.
