Flexible Access Gain

An universal Access Platform

4XE
Cost-effective cross-connect solution for linear, tree and star network topologies

AccessGain is an Univarsal Access Plaform, targeted to meet both typical carrier applications and access network needs.

4XE – cost-effective cross-connect solution for linear, tree and star network topologies

4XE is a flexible and multipurpose device. In combination with the DSL modem family and the Plex multiplexer, 4XE allows building access and transport networks of nearly any topology. It is optimal as an add-drop node for GSM base stations connection, subscriber and data connections along railways, pipelines, highways. At the Central Office side 4XE can be effectively used for creating star (point-to-multipoint) topologies and time-slot management in leased line networks. When CAS signalling supported by the switch and remote concentrator/multiplexer are not compatible, 4XE can be implemented as a signalling converter.

4XE - mediation device for centralised management networks

Centralised management is another important application of 4XE. In many cases, remote network nodes have another connection to the central management station then TDM based transport network. In this scenario the only transport media available for the management information is time-slots within E1 streams. 4XE can be used both for encapsulation of the management information into 64K time-slots on the central network side and for conversion of this info into RS232 management interfaces on the remote side. 4XE can be used for configuration of the remote shelves as well as for remote control of any other network elements supporting VT100-type management interfaces.
