UPCOM 8E1 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-8E1-4ETH, 8E1 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-8E1-4ETH is an IP over TDM converter, which supports the conversion from MAC frames to 1–8 E1 lines. The maximum bit rate is 16 Mbps (8E1 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. E1 interface ports ● Supports automatic removal and recovery of E1 channels that used for carrying payload. ● Supports the embedded E1 BER Tester function, to detect any E1 channel of 8 channels. ● Jitter tolerance and jitter transfer characteristic compliant to ITU-T G.823. ● The differential delay between any two of the 8E1 can be up to 220ms Ethernet Interface Ports ● Provides up to 4 shared Ethernet interfaces. ● 1024 MAC address table and 5-minute aging time. ● Accepts frames with length between 64 and 1916 bytes (otherwise filtering). ● VLAN setting function based on tags compliant to IEE 802.1Q. ● Throughout statistic of the Ethernet packets based on port, such as error packets. ● Configurable pause flow control. ● Optional optical Ethernet interface compliant to IEEE 802.3u 100BASE-FX standard and electrical Ethernet interface compliant to IEEE 802.3u 100 BASE-TX standard. ● 4 Ethernet ports are 10/100 BaseT Based, but fiber optical FX type ports are also possible with ranges up to 120 km. GUI Management Interfaces ● GUI via serial RS232 port and telnet. ● 8E1-4ETH network management platform based on SNMP. Support GFP-F encapsulation recommendation G.7041; Support Virtual concatenation(VCAT) and Link Capacity Adjustment Scheme (LCAS) recommendation G.7042; Support Ethernet to n*E1 mapping recommendation G.7043; Support Ethernet to single E1 mapping recommendation G.8040; Bandwidth is increased without damaging the Ethernet data; E1s in the local and remote sides can be arranged arbitrarily, such as: the remote E1 port 1 can communicate with local E1 port; Supports bandwidth unbalanced usage – when some E1s cannot work properly (i.e. the bandwidth of the sending and receiving can be 2E1 and 3E1 respectively); Provides the E1 connection-ship between local and remote system (accessed via GUI); E1 tributary signal loopback automatic detect and cut off; when some E1 signal is detected as looped back, it will be not employed for carrying payload temporarily, and when the loopback is broken, this E1 will resume to be used; Remote/local E1 loopback function will be convenient for E1 line (transmission system included) testing; Complete alarm which is selectable to be shown between local and remote. Historical & Current alarm databases; Single-board design with small dimension, 1U high and low power consumption; Support DC48V and AC 220V power supply; Support 0-50°C wide operating temperature range; Warranty:3years web:https://www.upcomnet.co , m/category/interface-converter-90.html
