Preface

The OptiX RTN 900 is a new generation split

microwave transmission system developed by Huawei.

It can provide a solution that is integrated with the TDMmicrowave, Hybrid microwave, and Packet microwave

based on the network requirements. RTN 900 V1R1

support pure packet microwave, and RTN 900 V1R2

support TDM microwave and Hybrid microwave.

Network Position

The OptiX RTN 900 is a new generation split microwave transmission system developed by Huawei. It

can provide a seamless microwave transmission solution for a mobile communication network or privatenetwork.

The OptiX RTN 900 products are available in two types: OptiX RTN 910 and OptiX RTN 950. The IDU of

the OptiX RTN 910 is 1U high and supports one or two IF boards. The IDU of the OptiX RTN 950 is 2U

high and supports one to six IF boards. The users can choose an appropriate type based on the actual

requirements.

The OptiX RTN 900 provides several types of service interfaces and facilitates installation and flexible

configuration. It can provide a solution that is integrated with the TDM microwave, Hybrid microwave,

and Packet microwave based on the network requirements. It supports the smooth upgrade from the

TDM microwave to the Hybrid microwave, and from the Hybrid microwave to the Packet microwave. The

solution can evolve based on the service changes that occur due to radio mobile network evolution.

Thus, this solution can meet the transmission requirements of not only 2G and 3G networks, but also

future LTE and 4G networks.

RTN 900 V1R1 support pure packet microwave, and RTN 900 V1R2 support TDM microwave and

Hybrid microwave.

EM6T/EM6FFront Panel

GE electrical interfaces on the front panel of the EM6T are compatible with the FE interfaces. The GE

interfaces on the front panel of the EM6F use pluggable SFP optical modules.

The FE electrical interfaces and GE electrical interfaces support the MDI and MDI-X adaptation modes.

The FE interfaces support 10M full duplex, 10M half duplex, 100M full duplex, 100M half duplex, and

auto-negotiation.

The GE electrical interfaces support 10M full duplex, 10M half duplex, 100M full duplex, 100M half

duplex, 1000M full duplex, and auto-negotiation.

The GE optical interfaces support 1000M full-duplex and auto-negotiation.

SP3S/SP3D Functions and Features

The SP3S is a 16xE1 75-ohm/120-ohm tributary board. The SP3D is a 32xE1 75-

ohm/120-ohm tributary board.

The E1 interface impedance of the SP3S/SP3D can be identified by the board feature

code of the bar code. In the bar code, the board feature code is the number next to the

board name.

AUX Functions and Features

The AUX is the auxiliary and management interface board of the OptiX RTN 950 V1R2.

One NE can house only one AUX.

The AUX provides multiple auxiliary interfaces and management interfaces, including the

one orderwire interface, one synchronous data interface, one asynchronous data interface,

and one four-input/two-output external alarm interface.

Provides one orderwire interface.

Provides one 64 kbit/s synchronous transparent data interface.

Supports one 19.2 kbit/s asynchronous transparent data interface.

Supports the input of four channels of external alarms.

Supports the output of two channels of external alarms.

Supports hot swapping.

Supports the detection of the board power supply.

The OptiX RTN equipment also supports the orderwire group call function. For example, when an OptiX RTN

equipment calls the number of 888, the orderwire group call number, all the OptiX RTN equipment orderwire phones

in the orderwire subnet ring until a phone is answered. Then, a point-to-point orderwire phone call is established.
