Raisecom Technology Co., Ltd 1. Overview RCMS2201/2401/2601-60 Ethernet Multiplexers are fiber-optic transmission devices for dedicated communication networks, data communication networks, switching networks, and also for point-to-point networks, medium-sized and small capacity networks. It can multiplex one E1 channel and one Fast Ethernet on to one fiber-optic cable, and implement the line-speed transmission of the Ethernet data.
Raisecom Technology Co., Ltd Providing 1 10/100Mbps auto-sensing Ethernet interface Providing 1 optical interface, multiplexing E1 and Ethernet data together Alarm indications of local and remote equipment Supporting E1 link remote loop-back function, easy fault location Supporting speed limit on both transmitting and receiving directions of Ethernet interface, increment 32kbps Implementation of SNMP, capable of local and remote management 1.
Raisecom Technology Co., Ltd 2.2 Fast Ethernet Interface Specification IEEE 802.3 IEEE 802.3u IEEE 802.1d Spanning Tree IEEE 802.1q VLAN Support oversized Ethernet data frame up to 1916 bytes Working mode: 10/100M Auto-Negotiation, Auto-MDI/MDIX (manual configurable) Flow control: IEEE802.3x and back pressure 2.3 Optical Interface Specification Bit rate: Fiber connector: Transmission distance: 2.
Raisecom Technology Co., Ltd Optical Connector: SC type in the above figure, TX for transmitting direction, and RX for receiving direction The optical interface type of RCMS2201-60 is DSC/PC, The optical interface type of RCMS2401-60 and RCMS2601-60 is SC/PC. L/R ALM (Fiber Local or Remote Alarm) The red alarm indicator will be lightened when error occurs at local or remote optical receiving direction. It includes 4 alarm levels: lose of signal, lose of frame, BER exceeds 10-3, and BER exceeds 10-6.
Raisecom Technology Co.
Raisecom Technology Co., Ltd remote site. 3． The equipment will monitor the status of optical link, either transmitting alarm or receiving alarm will be taken as an optical link fault. At the mean time, the Ethernet interface status will change to link down and the E1 interface will be cut off. The Ethernet interface and E1 interface will not recover until the optical interface recovers. The fault-pass-through capability is designed for users who have particular requirements.
Raisecom Technology Co., Ltd B． The both modules are installed in 16-slot 3U-high chassis, but only the host-site chassis is equipped with network management module. The remote-site module shall be set to “forced remote network management mode”. That is to say, the 8th switch shall be turned to ON. 4. Installation and Test 4.1 Inspect after Opening Please first check if the models and part numbers are in consistence, and also check if the equipments are damaged. 4.
Raisecom Technology Co., Ltd Pin 1, 2 for output of first E1 channel, pin 5, 6 for input of first E1 channel Pin 3, 4 for output of second E1 channel, pin 7, 8 for input of second E1 channel Ethernet Interface Connect with Cat. 5 or hyper Cat. 5 twisted-pair cables. Either straight-through or crossover cable is OK. Optical Interface Plug the tail fiber into the fiber socket to the end. 4.3.
Raisecom Technology Co., Ltd 6. Appendix A Cable Making A.1 E1 Cable Making Pin Number Definition 1 2 3 4 5 6 7 8 OUT1+ OUT1- OUT2+ OUT2- IN1+ IN1- IN2+ IN2- When user needs balanced signal, modules can be connected to 120ohm balanced E1 interface of other equipment as per above table. Pin 1 Pin 8 When user needs 75ohm unbalanced E1 interface, twisted-pair can be connected to E1 impedance converter. RC909-1E1 is single E1 channel impedance converter of Raisecom.
Raisecom Technology Co., Ltd A.2 Ethernet Cable Making Use Cat.5 twisted-pair cable with RJ45 connector to connect this equipment. Note that the cable shall not be longer than 100 meters. The cable can be either straight-through or crossover. The sequence of the RJ45 connector is as follows.
