Product Description

AN-STM-4-GETH Ethernet/STM-4 Converter provides access, converging, transmission and management functions for TDM services and wideband IP services based on SDH technology. It is a comprehensive access and conversion system for the conventional telecommunication services and the wideband data services.

 

AN-STM-4-GETH is an interface conversion equipment supplied with two STM-4 optical interface, two electrical gigabyte ethernet interface and two optical gigabyte ethernet interface.

 

AN-STM-4-GETH carries the data services via the container in SDH.

AN-STM-4-GETH applies 19″ rack of 1U high, which can be placed on the desktop or installed in a cabinet of 2.2m or 2.6m high, and can directly drive the top-mounted aural-visual alarm unit.

 

There are three power supply choices for AN-STM-4-GETH: AC ~220V, DC -48V, and AC ~220V with DC-48V backup. The choise is to be made by the user according to the actual situation.

 

The design of AN-STM-4-GETH complies with ITU-T and the relevant SDH specifications set forth by Chinese Ministry of Information Industry.
