 IF Channel Bandwidth: Set this parameter according to
the network planning documents. It can be set to 28M or
56M. If this parameter is set to 56M, the high-power
ODU must be used.
 Polarization direction-V/H: This parameter indicates
the polarization direction of a radio link. It is
recommended that you install the two IFX2 boards that
form an XPIC workgroup in the slots that are at the
same layer or in the same column. Set the IF port on the
IFX2 board that has a smaller slot number to
Polarization direction-V and that on the other IFX2
board to Polarization direction-H.
 Link ID-V/H: Set these two parameters according to the
network planning information. These two parameters
must be set to different values, but Link ID-V and Link
ID-H must be respectively set to the same values at both
ends of a link.
 Maximum Transmit Power: This parameter indicates
the max. transmit power of the ODU. The value of this
parameter must not exceed the rated power range
supported by the ODU. This parameter specifies the
upper threshold of the transmit power range of an ODU.
After an ATPC adjustment, the transmit power cannot
exceed the value of this parameter.
 Transmit Power/Transmission Frequency: Set these
two parameters according to the network planning
documents.

 If an ODU supports only one T/R spacing, set this parameter to the default value 0. The default transmission status of an
ODU is Unmute.
 Set ATPC parameters according to the network planning documents. Note that before the antenna alignment, ATPC
Enabled must be set to Disabled.

Time s lots for TDM S e rvice s on IF Boa rds
 When TDM services need to be transmitted on a radio link, you need to configure cross-connections between the
service timeslots on the corresponding service boards and the service timeslots on the corresponding IF boards. The
timeslots for the TDM services on IF boards are closely related to the type of the radio services transmitted by the IF
board and the radio capacity.
 TDM Radio

When the IF board works in PDH radio mode, if the microwave capacity is nxE1, the first to nth VC-12 timeslots
on the IF board are available and correspond to the first to nth E1s that are transmitted over radio. If a cross-
connection is configured between an E1 port on a service board and the second VC-12 timeslot in VC4-1 on the
IF board, the E1 services that are accessed through the E1 port are sent to the second E1 timeslot that is
transmitted over radio. If the radio capacity is E3, only the first VC-3 timeslot in VC4-1 on the IF board is
available and corresponds to the E3 channel that is transmitted over radio.

When the IF board works in STM-1 mode, all the timeslots in VC4-1 on the IF board are available and
correspond to the timeslots in the VC-4 that is transmitted on radio.
 Hybrid Radio
 When the IF board works in STM-1 mode, all the timeslots in VC4-1 on the IF board are available and
correspond to the timeslots in the VC-4 that is transmitted on radio. If an IF board works in Hybrid radio mode
and the E1 Capacity is set to n in Hybrid/AM Configuration, the first to nth VC-12 timeslots on the IF board
are available and correspond to the first to nth E1 timeslots that are transmitted over radio. For example, if the
E1 capacity is 75xE1, only the first to sixty-third VC-12 timeslots in VC4-1 and the first to twelfth VC-12 timeslots
in VC4-2 on the IF board are available. If a cross-connection is configured between an E1 port on a service
board and the second VC-12 timeslot in VC4-1 on the IF board, the E1 services that are accessed through the
E1 port are sent to the second E1 timeslot that is transmitted over radio.


Configuring Linear MSP (Optional)
①

②

③


Configuring Linear MSP (Optional)
Protection Type: can be set to 1+1
Protection or 1:N Protection. If extra
services need to be transmitted or
several working channels are
required, select 1:N Protection.
Switching Mode: can be set to
Select West Working Unit or West Single-Ended Switching or Dual-
Protection Unit from Select Mapping Ended Switching. If Protection Type
Direction. is set to 1:N Protection, Switching
This parameter specifies the mapping Mode can only be set to Dual-Ended
board and port in the mapping direction. Switching.
Revertive Mode: specifies the
revertive mode of the linear MSP. It is
recommended that you set this
parameter to Revertive.
WTR Time: specifies the wait-to-
restore time. It is recommended that
you use the default value 600 in
second.
Protocol type: ensure that the
interconnected NEs run the protocols
of the same type.


Configuring the Cross-Connections of
TDM Services
 In the case of 1+1 protection configuration or 1+1 linear MSP, you need to configure TDM services on
the working channel only. In the case of N+1 protection configuration or 1:N linear MSP, you also need
to configure the extra services on the protection channel if required.
①

③

④


Configuring the Cross-Connections of
TDM Services  This parameter indicates the level of a
service. If the service is an E1 service or a data
service that is bound with VC-12 paths, set this
parameter to VC12. If the service is a data
service that is bound with VC-3 channels, set
this parameter to VC3. If all the services in a
VC-4 pass through the NE, set this parameter to
VC4.

 Set the source slot, source port, source VC4,
and source timeslot of the service source. When
Source is set to the slot of the tributary board,
Source Port and Source VC4 are unavailable.
Set these parameters according to the network
planning information.

 Set the sink slot, sink port, sink VC4, and
sink timeslot of the service sink. When Sink is
set to the slot of the tributary board, Sink Port
and Sink VC4 are unavailable. Set these
parameters according to the network planning
information.


Creating Cross-Connections for
SNCP Services
 When configuring the SNCP services, you need to configure the cross-connections
of the SNCP services.
①

②

③

④


Creating Cross-Connections for
SNCP Services
 The cross-connection of SNCP services is a cross-connection that a working source and a
protection source correspond to a service sink.  This parameter indicates the level of a service. If the service is
an E1 service or a data service that is bound with VC-12 paths,
set this parameter to VC12. If the service is a data service that is
bound with VC-3 channels, set this parameter to VC3. If all the
services in a VC-4 pass through the NE, set this parameter to
VC4.

 Direction is generally set to Bidirectional.
 Hand-off Time specifies the duration of the hold-off time.
When a line fault occurs, an NE can perform SNCP switching
after a delay of time to prevent the situation where the NE
performs SNCP switching and other protection switching at the
same time. Set the hold-off time for the SNCP when the SNCP
works with the link-level protection schemes, including the 1+1
protection and N+1 protection. The hold-off time must be more
than the switching time of the protection scheme that works with
the SNCP. It is recommended that you set the hold-off time to 0
when only the SNCP is configured.

 Set the source slot, source port, source VC4, and source
timeslot of the working source and protection source. The
working service source and protection service source can be the
IF board or the line board. However, the IF 1+! protection board
cannot be used as the source of SNCP services.
 Set the sink slot, sink port, sink VC4, and sink timeslot of the
SNCP service sink. If Sink is set to the slot of the tributary board,
Sink Port and Sink VC4 are unavailable.

After the traffic control is enabled, if the link is congested, the Ethernet port sends the PAUSE frame to
notify the peer end of stopping the transmission of Ethernet packets for a period, thus eliminating the
link congestion.
 Required when the flow control function is enabled on the external equipment to which the Ethernet
port is connected. Set the parameters as follows:
 When the external equipment uses the non-auto-negotiation flow control function, set Non-
Autonegotiation Flow Control Mode to Enable Symmetric Flow Control.

 When the IF_ETH port transmits an Ethernet service that permits bit errors, such as a voice service
or a video service, you can set Error Frame Discard to Disabled.


Configuring the LAG
 Link aggregation allows multiple links that are attached to the same equipment to be aggregated to
form a link aggregation group (LAG) so that the bandwidths and availability of the links increase.
The aggregated links can be considered as a single logical link. Required if the LAG is configured to
protect the FE/GE ports or if the Hybrid radio uses the N+0/XPIC configuration mode.

 Set LAG Type to the same value as the opposite equipment.
Generally, set LAG Type to Static for the equipment at both ends.
 In the case of FE/GE ports, set Load Sharing to the same value
as the opposite equipment. If the LAG is configured only to realize
protection, it is commended that you set Load Sharing to Non-
Sharing for the equipment at both ends. If the LAG is configured to
increase the bandwidth, it is recommended that you set Load
Sharing to Sharing for the equipment at both ends. When the
Hybrid microwave uses the N+0/XPIC configuration mode, set Load
Sharing to Sharing for the equipment at both ends.
 Set Revertive Mode to the same value as the opposite
equipment. Generally, set Revertive Mode to Revertive for the
equipment at both ends. This parameter is valid to only LAGs
whose
 Set Load Sharing to Non-Sharing. Set System Priority to the
default value. This parameter is valid to only static LAGs.

 Set Main Board, Main Port, and Selected Slave Ports according
to the planning information. It is recommended that you set this
parameter to the same value for the main and slave ports of the
LAGs at both ends. The Hybrid/AM attributes of the IF ports in the
LAGs must be the same.


Configuring the LAG

 Port Priority indicates the priorities of the ports in a LAG as defined in the LACP
protocol. The smaller the value, the higher the priority. When ports are added into a
LAG, the port of the highest priority is preferred for service transmission.

 Set System Load Sharing Hash Algorithm to the same value as that of the opposite
equipment. Unless otherwise specified, this parameter takes the default value. This
parameter is valid to only LAGs whose “Load Sharing” is set to Sharing. The load sharing
computation methods include:MAC address specific allocation (based on the source MAC
address, destination MAC address, and XOR between source MAC address and source
MAC address), IP address specific allocation (based on the source IP address, destination
IP address, and XOR between source IP address and destination IP address).

Configuring the QoS
 By creating a DiffServ (DS) domain, you can create the mapping relation of a new DS domain and configure the ports that
use this mapping relation.
 P2P transparently transmitted services support mapping the PHB service classes based on the DSCP type only. The
default DS, however, maps the PHB service classes according to the CLAN priorities. Hence, you need to configure a new
DS.
①

 The OptiX RTN 900 has a default DS domain, for which Mapping Relation ID is set to 1 and
Mapping Relation Name is set to Default Map. Before another DS domain is created, all the ports
belong to this default DS domain. The default DS domain cannot be modified or deleted.

 Mapping Relation ID: indicates the ID of the mapping
relation between DS domains. The value ranges from 2 to

 Mapping Relation Name: indicates the name of the
mapping relation between DS domains. Set this parameter
according to the design.

 Package Type: indicates the type of the packet. The
packets trusted by the OptiX RTN 900 are the C_VLAN,
S_VLAN, and IP DSCP packets that carry the C_VLAN
priority, S_VLAN priority, or DSCP value. The untrusted
packets are mapped to the BE service level by default and
forwarded in best effort mode. The P2P transparently
transmitted E-Line service supports only the mapping from
DSCP packets to the PHB service class.

Ingress Mapping Relation: indicates mapping relations
between the priorities of ingress packets and PHB service
levels.

Egress Mapping Relation: indicates mapping relations
between the priorities of egress packets and PHB service
levels.

That is, except for the default value, Grooming Police After Reloading can be changed from
SP to WRR according to the queue priorities in a descending order (CS7-BE).
 Policy Weight: specifies the weight of the policy in the WRR queue. The weight indicates
the percentage of the bandwidth resources obtained by the WRR queue.

the PHB service class queues in the egress direction. CIR, PIR, CBS, PBS can be set only
when Bandwidth Limit is set to Enabled.

Creating Testing
remote MEPs

 Set the name of a maintenance domain. The
maintenance domain (MD) refers to the network for the
Ethernet OAM.
 Set the level of the MD. Values 0 to 2 indicate the
carrier level, values 3 to 4 indicate the supplier level,
and values 5 to 7 indicate the user level. When
Maintenance Domain Level is set to 0, the MD is at
the lowest level. Values 1 to 7 indicate that the level
increases in ascending order.

 This task is required in the case that the NEs where the two Ethernet interfaces involved in the
service test are located. Set the main parameters as follows:
 The MD names and levels of different NEs must be the same.
 In the test of Ethernet services between two edge nodes on the transport network, it is
recommended that you set Maintenance Domain Level to 4. In the test of Ethernet services
between two NEs within the transport network, set Maintenance Domain Level to a value
less than 4. In the test of Ethernet services between two Ethernet ports on the same NE, set
Maintenance Domain Level to a value less than that set in the test of Ethernet services
between two NEs within the transport network.


Creating Testing

An MD can be divided into several independent maintenance associations (MAs). By creating MAs,
you can associate specific Ethernet services with MAs. This facilitates Ethernet OAM operations.
