Description

Product Description The functional version of ISM6 boards is SL91. Application An ISM6 board provides two IF ports. The two IF ports can be used to implement XPIC, 1+1 HSB/FD/SD, or PLA/EPLA in one microwave direction, or provide microwave links in different directions. Scenario Where Two IF Ports Are Applied in the Same Microwave Direction ISM6 boards support XPIC/PLA/EPLA between intra-board ports as well as 1+1 HSB/FD/SD between intra- and inter-board ports. Figure 1 Scenario where two IF ports are applied in the same microwave direction Scenario Where Two IF Ports Are Applied in Different Microwave Directions An ISM6 board can transmit packets in two microwave directions through its two IF ports. Functions and Features ISM6 boards receive and transmit 2xIF signals, provide management channels to ODUs, and supply -48 V power to ODUs. ISM6 boards implement Ethernet and packet service functions by working with packet switching units on system control, switching, and timing boards. Table 1 Functions and features that ISM6 boards support Function and Feature Description Basic functions Receives and transmits 2xIF signals. Provides management channels to ODUs. Supplies -48 V power to ODUs. Radio types Integrated IP microwave SDH radio NOTE: Integrated IP microwave is compatible with Hybrid radio and Packet radio. Service types in Integrated IP microwave mode Native E1 + Ethernet Native STM-1 + Ethernet NOTE: Ethernet services can be native Ethernet services or packet services that are encapsulated into pseudo wire emulation edge-to-edge (PWE3) packets. One STM-1 service is equivalent to 63 E1 services. The total number of E1 and STM-1 services accessed on each board is less than or equal to 126 (the number of E1 services). Service types in SDH radio mode STM-1 2xSTM-1 NOTE: If one IF port provides 2 STM-1 microwave, the other IF port can only provide integrated IP microwave (the number of E1/STM-1 services is 0). Running modes In IS6-PLUS mode, the board newly supports large-capacity working modes. In IS6-PLUS mode, the ISM6 supports modulation schemes QPSK-4096QAM and two extended modulation schemes: QPSK Strong and 16QAM Strong. In addition, the ISM6 supports the 112 MHz channel bandwidth, under which the ISM6 supports modulation schemes QPSK-2048QAM and extended modulation schemes QPSK Strong and 16QAM Strong. IS6 mode, which is the default mode. In this mode, the modulation schemes QPSK-4096QAM and the two extended modulation schemes QPSK Strong and and 16QAM Strongare supported. The 112 MHz channel spacing is supported, and in this channel spacing, the modulation schemes QPSK-2048QAM and the two extended modulation schemes QPSK Strong and 16QAM Strong are supported. IS3 mode. In this mode, the modulation schemes QPSK-2048QAM and the four extended modulation schemes QPSK Strong, 16QAM Strong, and 512QAM Light, and 1024QAM Light are supported. ISM6 boards can interconnect only with ISV3 boards or the RTN 905. IS2 mode. In this mode, the modulation schemes QPSK-256QAM are supported. ISM6 boards can interconnect only with ISU2/ISX2 boards. NOTE: Compared with QPSK/16QAM, QPSK Strong/16QAM Strong has stronger FEC capability, and therefore has better receiver sensitivity. It has, however, less air interface bandwidth. Compared with 512QAM/1024QAM, 512QAM Light/1024QAM Light has weaker FEC capability, and therefore has worse receiver sensitivity. It has, however, higher air interface bandwidth. Once the running mode of either port on the ISM6 is changed, the other port automatically changes to the same running mode. Modulation schemes IS6-PLUS mode: QPSK Strong/QPSK/16QAM Strong/16QAM/32QAM/64QAM/128QAM/256QAM/512QAM/1024QAM/2048QAM/4096QAM IS6 mode: QPSK Strong/QPSK/16QAM Strong/16QAM/32QAM/64QAM/128QAM/256QAM/512QAM/1024QAM/2048QAM/4096QAM IS3 mode: QPSK Strong/QPSK/16QAM Strong/16QAM/32QAM/64QAM/128QAM/256QAM/512QAM/512QAM Light/1024QAM/1024QAM Light/2048QAM IS2 mode: QPSK/16QAM/32QAM/64QAM/128QAM/256QAM NOTE: In IS3 mode, 2048QAM is supported only when AM is enabled. In IS6 mode, 4096QAM is supported only when AM is enabled. In IS6-PLUS mode, 4096QAM can be supported only when AM is enabled. The highest-order modulation scheme that can be used by an IF port is determined based on factors such as the ODU frequency band, XPIC status, and channel spacing. For details, see ISM6 Board Microwave Working Modes. 112 MHz channel spacing Supported (only in IS6/IS6-PLUS mode) NOTE: If a channel spacing of 112 MHz is configured for one port of the two ports on an ISM6 board, the channel spacing of the other port automatically changes to 112 MHz. Similarly, when the channel spacing of one port of the two ports on an ISM6 board changes from 112 MHz to another value, the channel spacing of the other port changes to the new value accordingly.
