Basic functions Processes 12xE3/T3 signals.
Service processing
  • Transmits/Receives and processes 12xE3/T3 electrical signals.
  • Supports the E13 function, which is used to converge E1 services into E3 services.
  • Supports the M13 function, which is used to converge T1 services into T3 services.
Overhead processing Supports the setting and query of all the path overhead bytes at the VC-3 level.
Alarms and performance events Reports various alarms and performance events, which facilitates the management and maintenance of the equipment.
Maintenance features
