PT-50X 000X Ethernet Over E1 Converter supports the transparent transmission of Ethernet data on 1~8 E1 channels. It adopts international standard protocol (G.7041,G.7042,G.7043,G.8040) at the process for all layers and able to intercommunicate with third party device followed same standard. The device does not only provide perfect alarm/status indication for E1 and Ethernet, but with advanced management function such as Ethernet data traffic statistics etc. The device is with high integration, low power consumption, stable performance and easy to use.
PT-50X Ethernet Over E1 Interface Converter adopts international standard protocol at all levels, which can also communicate with the similar product of other manufacturers.


Features
* Transmission over E1 interfaces;
* Auto adaptation of Ethernet data over 1~8E1;
* Auto-restore of E1 link after eliminating the failure;
* For 8E1 channels, the maximum tolerable time delay between links can be up to220ms. It will have an alarm for exceed the limit when the time delays over 220ms. E1 link comply with jitter tolerance and jitter transfer characteristics of ITU-T G.823;
* 10/100BT Ethernet interface, provide4 maximum shared Ethernet interfaces;
* Support VLAN based on interface, fully comply with IEEE 802.1Q standard;
* Support frame length: minimum: 64 bytes, maximum: 1916 bytes;
* Provide statistics for each Ethernet interface, such as the fault package number andtotal package number etc;
* Support hyper terminal or SNMP/WEB management;
* GFP-Fen capsulation complies to G.7041;
* VCAT and LCAS complies to G.7042;
* Ethernet to nxE1 mapping complies to G.7043;
* Ethernet to E1 mapping complies to G.8040;
* The Ethernet data will not be damaged if enlarge or reduce the transmission bandwidth by means of network management;
* Asymmetric transmission supported, when a one direction of the E1 is failed, the other direction can still work;
* E1 channel will be cut off when in loop back and restore when loop back is removed;
* Provides alarm indication, display local or remote optional;
* Support local E1 circuit loop back function, facilitate to test E1 circuits;
