Global competition forces operators to reduce OPEX and CAPEX. To address the issues, the market mega-trend is moving toward the ubiquitous transport networks by use of Ethernet to transport TDM, SONET and Packet. By supporting PBT/PBB-TE, MPLS-TP(*) and OAM(802.1ag, Y.1731), MTS-M180 is well positioned to the Packet Transport Network and are capable of dealing with costeffective transport aggregation traffic for many high-speed access networks. E-LINE, E-LAN and E-Tree services in MTS-180 can provide differentiated QoS and SLA assurance for Ethernet private line services. In addition, MTS-M180 significantly reduce OPEX by providing easy migration from legacy TDM to Ethernet networks with seamless support of SONET/SDH grooming, cross-connect and transport service. Cost-effective mixture of Ethernet and TDM traffic allows MTS-M180 to provide an agile platform for the deployment of point-to-point private line service for both TDM and Ethernet. MTS-M180 especially provides an ideal and costeffective service for transporting SONET/SDH over Packet Transport Network.

Wireless backhaul solutions

Today’s traffic in the wireless backhaul is steadily increasing by video and data traffic over the voice service network. Unfortunately current TDM based wireless backhaul capacity is hardly able to keep pace with the relevant bandwidth growth. On other hand, the ARPU (Average Revenue Per User) is not growing as much as bandwidth growth is. We believe that Carrier Ethernet is a unique solution to reduce OPEX and CAPEX for the wireless operators. Dowslake‘s MTS-M series provides seamless migration path from current legacy based radio access networks to full Carrier Ethernet Networks. MTS-M180 are the most compact but highly integrated Ethernet based radio access networks equipment in the world.

Importantly, with the beauty of 1RU size form factor, MTS-M180 provides 28G switching capacity with 4 ports GbE and 2 ports 10G networks aggregation capacity. In addition, MTS-M180 has two optional modules for highly integrated TDM based interface modules. Specially, STM-4 capacity line card provides full featured PWE3 functionalities including SAToP, CESoP, ATM/IMA, clear channel and CEP for VC12/VC11/VC3/VC4 level.
Finally, MTS-M series is ideally suited to the following
applications:
-Wireless backhaul network for cell site, hub and
aggregation node
- Transport SONET/SDH over packet transport network
- T1/E1 private line service
-Ethernet virtual private line service

MTS-M180 is a flexible multi-service access switch with two available optional slots which fit for various types of TDM and Ethernet multi-service line cards. The User Service modules are available for STM-1/OC-3, E1/T1 and Ethernet services. The MTS-M180 can locate as a small scale aggregation site for the wireless backhaul network. The compact design of MTS-M180 1U height supports very low power consumption and saves space. The MTS-M180 offer a full scale of carrier class high availability with G.8032 ERP (Ethernet Ring Protection). The ERP function provides SONET level of protection within 50m seconds. In addition, the MTSM180 offers carrier grade OAM features, such as 802.3ah, 802.1ag and Y.1731.generation either collectable via user-management interfaces CLI or SNMPv1/v2/v3.
