Introduction GOAL: improve communications in Catalonia

designing a fibre optical network through SDH technology.

Three types of customers:

Residential

Enterprise

Administration Population of Catalonia Traffic oversize of 25% The majority of nodes are

placed in regional capital

≈ 19Gbps

Important points:

• 4 links to access the CATNix node. Distributed traffic.

• Barcelona City is divided in two rings.

• Two nodes are the gateways to the network’s Backbone (Sant Feliu & Sabadell).

• Our main goal is to distribute the traffic.

Synchronization Follow recommendations ITU-T G.803 Synchronization is carried across the network using the

STM-N signals Each network device will select the highest quality timing

reference clock, chosen by the synchronization status messages (SSM) SSM: SDH/SONET protocol that communicates information about

the quality of the timing source Hierarchical Master-Slave synchronization. Equipment Required
