415-CEX2 - Serial Interface Converter
Or call us on

The CEX2 serial interface converters offer conversion between E1 (G.703/G.704) and standard data communication interfaces. The units convert X.21, V.24, ISDN BRI (I.430) and Ethernet Bridge to E1 (2.048 Mbps) interface (ITU-T G.703) where interface data rate can be set in steps of n x 64 kbps up to 2048 kbps (unframed mode) via SNMP, Web-GUI, Telnet and VT100 management. When equipped with a 10/100BaseTx user interface, CEX2 is able to connect remote LANs transparently. It supports auto- negotiation, full- and half-duplex mode, Flow control and transmission of VLAN frames up to 1522 bytes. The CEX2 offers in-band management of the remote device, whereby the management data is transmitted together with the user data. The in-band management capability in combination with System Controller SCX2 allows Carriers and ISPs to maintain and supervise all devices inside management system via single NMS access point (IP forwarding). Additional features like performance monitoring (E1 ports) and several test loops at line and user interface ports give operators wide bunch of easy service diagnostics in case of any problems in the network.
