RC959-4FE16E1 is an inverse multiplexer that transmits Fast Ethernet service over bonded E1 circuits. The device is typically deployed in pair, and can deliver 2~32Mbps Ethernet service according to customers' requirements. Designed following the standard GFP EoPDH encapsulation, the device supports LCAS, with which the service channel established by the pair of device will not be down even if unstable or broken-down E1 links exists in the TDM network.

RC959-4FE16E1 provides 16 VCG, which allows carriers and service providers to access multiple users and provision service channel bandwidth conveniently.

The device has three working mode: VLAN unaware mode, VLAN aware mode and Q-in-Q mode. When working in VLAN unaware mode, the device will forward any packets received. When working in VLAN aware mode or Q-in-Q mode, the device will forward received packets according the pre-set forwarding rules based on VLAN tags.

RC959-4FE16E1 supports various diagnostic tools such as local and remote E1 loopback, E1 BER testing, loopback detection, and etc. The pair of RC959-4FE16E1 can also be fully monitored and managed on the GUI of Raisecom NView NNM system. All this tools provide ways of quick fault isolation, which will help save time and cost of carriers and service providers.
