0TS-622 is multifunctional transmission equipment, has STM-1 and STM-4 optical interface with standard transmission rate, slot-structure, multiple light directions, high integrated E1 board and multi-channel shared Ethernet card. OTS-622 is an ideal network gateway equipment for small volume optical transmissions.

OTS-622 equipment supports 1008×1008VC12 / 48×48VC3 / 16×16VC4 non-block crossing and ADM. It also has the uni-directional and bi-directional broadcasting function.

Its network management can support assignment, warning, maintenance, supervision and management functions.

 

OTS-622 contains 2 optical interface on the main board, besides 4 expansion slots. E1 card, Ethernet card, Optical port card extensible.
