OGM-30E

OGM-30E

Multifunctional multiplexer OGM-30E is designed to form E1streams  by multiplexing analog voice signals and digital data signals with the ability to specify work modes programmatically.
The equipment can be used in rural, urban, departmental, area and main communications networks, as well as in organization operational communications networks as:

  • terminal multiplexer;
  • add / drop multiplexer;
  • add / drop multiplexer with group channels;
  • cross-connect multiplexer;
  • converter of interoffice signaling;
  • subscriber access unit to PSTN and ISDN networks.

Features
