Typical Application of RTN 980s - TDM

Application 1: TDM services from BSs are converged and then transmitted to an

optical transmission network.

This application pertains to the backhaul of TDM services from BSs. The services from BSs are

converged on an RTN 980 on a chain, tree, or ring network. If an NE needs to transmit 16xE1

services, 1+1 HSB protection must be configured for the NE. In addition, this NE provides

STM-1/STM-4 optical interfaces in the upstream direction, which is configured into a 1+1 MSP group. RTN

980s connect to a backbone network, and is configured into a ring MSP group with OptiX OSN

equipment.

Typical Application of RTN 980s - Hybrid

Page 11 MSTP/PTN RTN980 STM-N/GE Ring RTN RTN RTN TDM MW Convergence of multiple types of IF boards

On the access side, TDM and Ethernet services are transmitted to one site and are converged on Hybrid IF

boards on the RTN 980. Then, the services are transmitted to optical transmission networks. Specifically,

TDM services are transmitted on an SDH network; Ethernet services are transmitted on a GE network.

Application 2: Hybrid services from 2G/3G BSs are converged and then transmitted to an optical transmission network.

Hybrid MW

(12)

Typical Application of RTN 980s - Packet

The RTN 910 receives Packet services from the BS, and the RTN 950 or RTN 980 converges services. The services from the RTN 950 are transmitted to the PTN 3900 through a GE access ring. The RTN 980 converges services from eight microwave directions or more. The RTN 980 provides two GE ports in the upstream direction to connect to the PTN 3900. In this way, microwave equipment and other optical network equipment can be integrated as one. In addition, Nodal microwave equipment instead of stacked devices can be used to receive services from multiple microwave directions.

Application Scenario of the CSHN Board

Configuration Principles

CSHN boards are a must for an OptiX RTN 980. If an OptiX RTN 980 needs one CSHN board,

install the board in slot 15; if an OptiX RTN 980 needs two CSHN boards, install the boards in

slots 15 and 20.

Typical Application of STM-1/STM-4

Compatible Optical Interfaces

1. RTN 980s can be networked with fiber-optic equipment. That is, RTN 980s

can be networked with MSTP equipment to form an STM-4 ring, or can be

networked with MSTP equipment to form an STM-1 ring.

2. If there are two system control, switching, and timing boards, the boards

cannot be configured into STM-1 linear MSP with extended boards.
