InterGlobe provides advance DXX which terminates asynchronous and SONET signals. It interconnects and monitors these signals, selectable either as DS3, EC-1/STS1, or VT1.5/DS1 level with performance monitoring on every embedded signal. The I/O interfaces include DS1s, DS3s, STS-1s, OC-3s, OC-3cs and OC-12cs. Its capacity ranges from 1 port to 3,360 DS3 equivalent ports to support the growth and ensure the reliable operation of the most complex networks.
