_____________________________________________Presentation This presentation to summarize the project as shown during the INFN engineers visit in Alcatel premises on 14-15th of June 2001. _____________________________________________ With this system will be possible to set up 1024 STM-1 bi-directional SNCP protected paths. With the NMS will be possible to monitor alarms, to perform remote commands and to set up the necessary paths and protection. Service Provisioning: interface functions to allow SML to perform Service Delivery. Service Charging&Billing, Service Assurance Note: depending on “pitch” of presentation, a deeper analysis of this may be presented using confidential slide on management architecture of multi-technology service network Single interface: all functions described are provided using the same interface (hereafter called Isn) Single point: SML connects to NML at one point only; (within NML, Isn request is translated and distributed as appropriate to the relevant NML/EML/NEs) Multi-technology interface: to manage new technologies as well as existing ones in an integrated way, and so cater for - SDH/PDH transport network - ATM network - IP network - Access network Presentation, June 15th 01, page n° 2 » All rights reserved © 2001, Alcatel

All common cards are protected EPS 1+1.1660SM Each 1660SM will be equipped with 16 Optical STM-1 tributary to the tower that will be protected with EPS N+1 and 2 Optical STM-16 (Colored) interfaces to the DWDM systems for the SNCP protection. All common cards are protected EPS 1+1. Subrack Size = 482W x 250D x 650H mm Consume = 211W (if equipped with 16xSTM-1 + 2xSTM-16) Presentation, June 15th 01, page n° 4 » All rights reserved © 2001, Alcatel
1660SM - Optical STM-1 moduleThis Optical Module (S-1.1) will be used as Electrical/Optical converter within the customer equipment in both sides, under sea and in the landing station. Consume = 1,5 W One module for each floor of the tower. receiver in the landing station. Presentation, June 15th 01, page n° 5 » All rights reserved © 2001, Alcatel
1686WM These equipment are used to concentrate 16xSTM-16 channel to one lambda. 4x1686WM are necessary to carry the main traffic and other four to carry the protection. A booster +14/+17dB will be necessary depending on the real length of the submarine cable. Subrack Size = 482W x 250D x 400H mm Consume = 90W (if equipped with 16 and a +14dB booster) Presentation, June 15th 01, page n° 6 » All rights reserved © 2001, Alcatel
