OMS 3250

Product DescriptionOMS3250MSH2KHO-VCSWITCH15STM-n @VC-4/4-nc2adaptation43LO-VCSWITCHFigure 11: Processing inside the LO Stitching matrix• Cross-connection at LO-VC level (and eventually at HO-VC level) of the traffic received fromthe "tributary" STM-n interfaces, directly mounted on both the LO-VC Switch cards is up to acapacity of 10G (i.e. up to 5G collected by Unit A and 5G collected by Unit B). In this waythe LO SWITCH unit performs the classic features of a 4/1 ADM, integrated inside theOMS3250:- Ring closure, at LO-VC level, of the traffic received from two "tributary" STM-ninterfaces; please note that in order to assure the protection in case of failure of one ofthe LO SWITCH units, the two STM-n interfaces, involved in the Ring protection, mustbe placed: one on Unit A, the other on Unit B- Collection of LO-VC distributed on different tributary STM-n interfaces and crossconnection.The LO-VC can be then re-routed to another tributary STM-n interface orcan be groomed in TUG structured VC-4 and forwarded to the HO switching subsystem.Page 38 of 74 Copyright – Refer to Page 2 Issue 1
