Brief introduction of device
CiTRANS 620A is a packet intelligent optical transport platform based on MPLS-TP technology and located at the edge layer. The switching capacity of the device supports 6G, and provides interfaces such as E1, GE, FE, clock and time synchronization, which are mainly used in edge access points.
CiTRANS 620A has the following features:
Support TDM, ETH mixed service access, and provide flexible service access and scheduling capabilities
Support PW 1:1 protection, PW redundancy protection, etc., and provide rich network-level protections
It is suitable for 19-inch and 21-inch cabinet installation, wall mounting and outdoor cabinet installation, and provides flexible installation methods
The CiTRANS 620A device includes two models, i.e. CiTRANS 620A-2A (AC model) and CiTRANS 620A-2D (DC model), the external view of device is shown in Figure 1-1 and Figure 1-2.
Network Application
CiTRANS 620A is a packet intelligent optical transport platform located at the edge layer, which realizes the service aggregation of the edge access layer.
Typical networking of the CiTRANS 620A is shown in Figure 1-3.
