• Configuration should be according to network management plan.• ZXMW NR8250 V1.00 supplies static route configuration function for connecting with third-part

equipments, and still the equipment works as L2 switch.

4.3 Shelf Configuration(2/2)

• According to the actual situation of the boards inserted in IDU’s slots, set the following information for each SLOT NO.: Board Type, Transmit Unit, Function, and select Master Slot or Slave Slot.– If Function of RTUB board is set to STM-1 ADM/TM, E1 and STM-1

service are supported.– If Function of RTUB board is set to STM-4 /STM-1 Transparent, E1,

STM-1 and STM-4 service are supported..– Function is set to default for other types of boards.

• Note:– Slot 1 can only be set to RCUA board.– Slot 2 can be set to RCUA or RTU board.– Slot 3-8 can be set to RTU or RMU board.

4.4.2 Working Mode Configuration

• Select the bandwidth assigned to TDM service in the Work Mode drop-down list box, and the rest bandwidth will be assigned to Ethernet service.

• Bandwidth and modulation mode decide the capacity of transmission. Boarder bandwidth and higher modulation mode will offer more capacity at the cost of transceiving performance degradation.

• Configure the Protection Type according to the MW design.– No Protection indicates the system has no protection.– HSB indicates the system adopts the protection of 1+1 hardware hot backup. – SD indicates the system adopts the protection of antenna diversity reception.– FD indicates the system adopts the protection of different transmitting and receiving

frequencies.

• If one type of protection is adopted, the Protection Mode can be configured.– Revertive indicates when service signal on active path become normal, the service will

switch back to it, and the Revertive Time should be set, which range from 300s -800s.– Automatic indicates the system will switchover automatically according to the status of

active and standby path.– If Manual is selected, and the protection type is HSB or SD, the IF&RF Tx Path should be

specified. If protection type is FD, only IF TX Path need to be specified.

4.4.3 Protection Parameter Configuration

>Internal only


• If ATPC Enable is set to ON, ATPC High Threshold and ATPC Low Threshold should also be configured. Usually, the two parameters are recommended to use the default value.

• Max Tx Power and Min Tx Power need to be set within the range of ODU transmitting power.

• When adjusting the antenna, ATPC Enable must be set to OFF.

4.4.4 ATPC Parameter Configuration

>Internal only


• The unit of Current Rx/Tx Frequency is kHz. • The Tx Frequency should be set within the Tx Frequency Range.• The RSL High Threshold and RSL Low Threshold can be set to

default value if there’s no special requirement.

• Clock Protection Switching Strategy ：– No Protection Policy ： Only adopt the primary clock, if the primary clock degrades, it will keep

current frequency for a bit of time, then switch to enforced clock PLL free running.– Auto-switching Policy （ Non-real-time priority switching ）： Switch to subordinate clock if exists

when primary clock is degrading or lost and wouldn’t switch back to primary clock even if primary clock turns normal.

– Optimal Switching Policy （ Real-time priority switching ）： Switch to subordinate clock if exists when primary clock is degrading or lost and switch back to primary clock if primary clock turns normal.

• GPS M/S Stations ：– Mater Station ： Select GPS Master Station when the clock in RCUA board works as clock

source.– Slave Station ： Other conditions.

• BITS Clock Output ：– Open ： Clock signal is output from CLK IN/OUT port.– Close ： No clock signal is output from CLK IN/OUT port.

• BITS Clock Mode can configure the clock mode ， normally chose 2.048Mbps.• Enforce Clock PLL Free Running can chose Yes or No ， chose Yes when transmitting

synchronous Ethernet service.• NE in Ring Network, configure according to real situation.
