SmartAX MA5680T is the global first OLT which integrates the functionality of aggregation switch and edge router.
The MA5680T provides the voice, data, and video services that feature large capacity, high rate, and high bandwidth. To be specific:
The MA5680T functions as an optical line terminal (OLT) in a GPON network to work with the optical network unit (ONU) and optical network terminal (ONT).
The MA5680T supports rich network applications, such as FTTH, FTTB, and FTTC.
The MA5680T meets the network requirements of base station transmission, IP private line interconnection, and multi-ISP wholesale
Working Principles The ETSI shelf consists of functional modules. These modules support the access and the upstream of the service. The ETSI shelf consists of the following functional modules: l Ethernet switching module l Control module l Service interface module l Network interface module Ethernet Switching Module The Ethernet switching module is the core of the entire system. It converts data and processes protocols between the service board and the control board.
Control Module The control module consists of the control board, subboard, and related software. This module performs the following functions: l Controls the system and service switching. l Provides the environment monitoring port for connecting to the environment monitoring module.Signal direction in the shelf
- The xDSL service board accesses the xDSL signals and converts them into the Ethernet service signals.
- The AIUG service board accesses the ATM signals and converts them into the Ethernet service signals.
- The BIUA board accesses and transmits the BITS signals as the input or output clock of the device.
- The OPFA service board accesses the FE optical signals and converts them into the Ethernet service signals.
- The GPBC service board accesses the GPON signals and converts them into the Ethernet service signals.
- The ASRB service board accesses the POTS signals and converts them into the Ethernet service signals.
- The Ethernet service signals are transmitted to the control board, uplink board, or TOPA board through the backplane bus. Then, the Ethernet signals are forwarded upstream through the control board, uplink board or TOPA board.
- The ETHA service board or the uplink board accesses the Ethernet subtending signals. The Ethernet subtending signals can be transmitted upstream after being transmitted to the control board or TOPA board through the backplane bus. Or the Ethernet subtending signals are transmitted upstream by the uplink board directly.
