Fast Ethernet and 4E1 multiplexer (RP102)

Overview       

RP102 is the compact and high-performance optical transmission equipment based on Application Specific Integrated Circuit (ASIC). It can realize the 4 E1s and a 100Mbps Ethernet data channel transmission over optical line.

With low power consumption, high integration and well stability, RP102 can be used point-to-point, or as the remote of RS7000/RS3000 (MSAP), it is a cost-competitive solution for the application such as the telecommunication, the electric power and the finance fields.

Feature 

• Compact design with 1U height, and can be installed on standard rack
• Realizes 4 E1s and a 100M wire-speed Ethernet mixed multiplexing to optical fiber
• Optical interface
• One optical interface, with the line bit rate of 155Mbps.
• Provides optical loopback function, a great convenience for trouble shooting.
• Supports remote power down information sending function.
• E1 interface
• Provides 4 E1 interfaces, 75Ω unbalanced, and BNC connector.
• Jitter tolerance and jitter generation fully comply with ITU-T G.823 recommendations.
• Supports device loop and E1 line loop for easy testing.
• Ethernet interface
• One copper fast Ethernet interface compliant with IEEE802.3 serial standard (RJ45).
• Supports auto-negotiation, which can work in 100M full/half-duplex, 10M full/half-duplex mode.
• Accepts frames with length between 64 and 2036 bytes (otherwise filtering).
• Flow control ability in full duplex mode.
• Auto MDI/MDX function.
• Patent technique adopted for Ethernet loop detection.
• Management
•  Necessary alarm detection for fault location.
•  Supports management by RS7000/RS3000.
•  

Application

RP102 supports point-to-point application, as Figure 3-1 shows.

Figure 1 Point-to-point Application

RP102 can be the remote of RS7000/RS3000 (MSAP equipment), as Figure 3-2 shows. The NMS can monitor and control all RP102 via RS7000.

Note：This application is only for the E1 traffic aggregation; Ethernet traffic aggregation is not supported.
