CS3400 Cell Site Switch is a Carrier Ethernet switching platform that delivers high efficiency IP based packet traffic. CS3400 is typically to be placed at eNB sites as a DU (Digital Unit) device. CS3400 can provide Pseudo Wire Emulation service for TDM traffic, offering legacy data services over IP based network for business service as well as 2G or 3G mobile backhaul infrastructure.

Multi-node ring structure

  • Up to 8 units of CS3400 comprise a highly manageable and reliable ring architecture which is protected based upon G.8032 Ethernet Ring Protection Service protocol. It supports less than 50 ms switch-over so as to achieve the high resilience requirement of industry.

Fault and Performance management

  • CS3400 supports IEEE 802.1ag CFM (Connectivity Fault Management) with the Maintenance Domain Level of Provider and Operator. Also the performance related features defined in ITU Y.1731 are implemented for better manageability.

Various types of Interface Module

  • According to the customers need CS3400 can furnish the best fit interface module card unto the unit, which can be Gigabit Ethernet either in SFP or UTP form, 10G Ethernet or E1. There are 4 available slots for these modules which can be equipped with any one type of interface module cards homogeneously or with mixed types of cards at the same time. The followings are the species of interface module card:
  • CS3400-4F card
    - 4 port 1GE SFP module (1000Base-X)
  • CS3400-4T card - 4 port 1GE Tx module (1000Base-T)
  • CS3400-1X card - 1 port 10GE module
  • CS3400-6E1 card - 6 Port E1 module

Adaptability to Operating network

  • According to the type of Metro Ethernet implementation which customers have implemented, CS3400 can adapt itself to provide the required transporting capability. For this purpose CS3400 adopted the prevalent technologies of PB (Providers Backbone, 802.1ad), PBB (Providers Backbone Bridge, 802.1ah) and MPLS.

Redundancy of Power module

    Two power modules are redundantly equipped at rear side of the unit which are hot swappable for the
