Aggregator MS-1S-21E

Transmits up to 21 E1 client interface in STM-1 channel

  • Transfer client signals E1
  • STM-1 Line Interface
  • Internal or external synchronization

The E1 channel aggregator STM1-21E1 is designed for receiving / transmitting twenty-one streams in E1 format (2048 Kbit / s) from / to the SDH transport network of the STM-1 level. Each port of the device works in full-duplex mode. The client E1 channels are connected to the device via RJ-45 connectors. The signals can be synchronized with two inputs (2048 kHz) and two outputs (2048 kHz), in accordance with G.703 / 13.
