The two IF ports can be used together or independently. Supports the EPLA /EPLA+ function on OptiX RTN 950A.Supports AES256-based encryption at air interfaces.Supports air-interface bandwidth acceleration (Ethernet frame header compression) and enhanced Ethernet frame compression (payload compression).When working in IS2 mode, ISV3 boards can interconnect with ISU2/ISX2 boards. IS2: The highest-order modulation mode is 256QAM.When working at a channel spacing 3.5 MHz, ISV3 boards can interconnect only with ISV3 boards. When working in IS3 mode, ISV3 boards can interconnect with each other or with RTN 905s. IS3: The highest-order modulation mode is 2048QAM.Supports the EPLA function on OptiX RTN 950A.Supports air-interface bandwidth acceleration (Ethernet frame header compression).Supports integrated IP microwave and SDH microwave using the Native E1+Ethernet, Native STM-1+Ethernet, or SDH service mode.Supports modulation schemes from QPSK to 256QAM.Provides a USB port that allows data to be backed up using a USB flash drive.Ī CSHO board can house a WLAN module only when using the SLF2 functional version.Provides one Huawei outdoor cabinet monitoring port, which uses the same physical connector as the second external time port.Provides one Ethernet NM port, one NM serial port, and one NM cascading port.The GE electrical ports are compatible with the FE electrical ports. Provides six GE ports, of which four can only be RJ45 GE electrical ports and the other two can be GE/FE optical ports or GE electrical ports equipped with SFP modules.Only SLF2CSHO boards support T1 ports. When CSHO boards work with MN1 boards, these TDM E1 ports can be configured as Smart E1 ports, which support CES E1s, ML-PPP E1s, and fractional E1s. The mode of a TDM E1/T1 port can be configured through software. Supports E1 ports support 75-ohm/120-ohm adaptive impedance. When CSHO boards work with MN1 boards, these ports can be configured as channelized STM-1 ports, which support CES E1s and ML-PPP E1s. Uses SFP modules to provide two STM-1 optical /electrical ports.The first external time port uses the same physical connector as the external clock port. Supports the clock processing function, providing one external clock input/output port and two external time input/output ports.Provides two -48 V DC power input ports.Performs system communication and control. The new SLF2CSHO board supports 元VPN functions (SLF2 is the functional version).Provides a 10 Gbit/s packet switching capability.Provides full time-division cross-connections of VC-12/VC-3/VC-4 services equivalent up to 32x32 VC-4s. Hybrid system control, switching, and timing board
