• Smooth and cost-effective in-field network upgrades: from 2.5G to 10G, leveraging huge operators' 1660 SM existing assets at minimal CAPEX and OPEX
• Guaranteed customer service reliability: protection methods
• Unrestricted deployment of hardware items across systems, synergy in spares and spare management, easy repairs and reduced training requirements: through the common building block concept of the Optical Multi-Service Nodes and Gateways (OMSN and OMSG) product family
• Reduced OPEX: simplified network operations and operators' staff training thanks to the Alcatel-Lucent unified network management system, which offers integrated end-to-end service management functions with the same look and feel for all Alcatel-Lucent's transmission products

The Alcatel DVB-ASI enables broadcasting companies to transport digital video broadcasting (DVB)-compliant signals over the same unique reliable optical infrastructure. In the recent past, video transmission across wide metropolitan areas required a costly overlay network separate from voice and data networks due to a lack of digital video interface standards, designed for WAN transport. The deployment of the Asynchronous Serial Interface (ASI) together with the packet-adaptation capability offered by the Generic Frame Protocol (GFP), have recently allowed packet-based transmission of compressed video signals over next-generation SDH equipment. Such capability streamlines bandwidth optimization compared to the traditional ASI/ATM/E3/FE broadcast transmission.

The Alcatel DVB-ASI card (coexisting with the ISA-ESx series) plugs into optical multiservice nodes and acts as a network adapter (NA), allowing optimized encapsulation of digital video signal within SDH frames. This way, broadcasters can deliver digital broadband video, broadband data, video on demand (VoD), telephony, and other business services over the same converged networks. One single multiservice infrastructure allows digitally compressed video signals to be deployed both for primary distribution (point-to-multipoint) and for contribution (point-to-point). In both cases, the node and network architecture must assure reliability and flexibility — reliability to protect NAs from failure adopting EPS schemes, and flexibility to enable the operator to efficiently configure SDH paths. Figure 1 depicts the reference model for a compressed video environment according to the European Broadcasting Union (EBU). Video transport applications are typically unidirectional.

The Alcatel DVB-ASI NA has a port card and an access card, along with a special access card that is used to implement 1+1 EPS. Physical card dimensions are the same as those of the Alcatel OMSN family; each card occupies one slot. Figure 2 depicts the slot definition of the Alcatel 1660 SM. DVB-ASI NA port cards can be housed in slots 24 to 31 and from 32 to 39 in the basic area. For each port card, the corresponding DVB-NA access card must be housed in access area slots with a fixed relation to those in the basic area (respectively from 2 to 9 and from 13 to 20). The access card contains four BNCs (J1 to J4), which correspond to input (TX) channels from 1 to 4,while the four BNCs (J5 to J8) correspond to output (RX) channels from 5 to 8. Up to 16 ISA ASIs can be plugged into the Alcatel Optical Multi-Service Node (i.e., 1660 SM). RX and TX can be independently set up.

> Electrical interfaces

> DVB-ASI interfaces According to CENELEC EN 50083-9

> Line driver and equalization to guarantee up to 150m of Belden 1694A coaxial cable

The following alarm radixes are provided:

> DVB-ASI LOS (loss of signal), LOA (loss of code word alignment: no /K28.5/), LOF (loss of transport packet (TP) frame: no valid TP) are mapped to generic client LOS. In the case of client signal fail (CSF), the egress DVB-ASI stream is an invalid 10B code word sequence

> Exceeding input bit rate is the only specific alarm

> No server signal fail (SSF) special consequent actions: egress DVB-ASI stream is an invalid 10B code word sequence

No specific performance monitoring: only SDH-related performance monitoring is provided.

Board management is completely integrated into the Alcatel 1660 SM equipment. Both local management through a craft terminal (CT) and remote management through communication to the 1350 Network Management (NM) are possible.

TECHNICAL SPECIFICATIONS

The main characteristics of the Alcatel DVB-ASI NA card include:

> Unidirectional transparent transport of constant bit rate (CBR) MPEG-x transport stream (TS) either single program (SPTS) or multiple program (MPTS) with TS rate ranging from 1.5 Mb/s up to 100 Mb/s (with C-12 or C-3 granularity)

> MPEG-x TS NA functionalities integrated into Alcatel 1660 SM ADM equipment comprising SDH functionalities according to relevant ETSI and ITU-T standards currently deployed in OMSN equipment

> (1+1) non-revertive EPS board protection (SDH matrix and common parts equipment protections as usually implemented in OMSN equipment)

> Network protection through SNCP of VCGs (LCAS not applicable for unidirectional transport)

> Point to multipoint capability through broadcasting SDH VCs

> DVB-ASI interfaces, widely adopted by video equipment, according to CENELEC EN 50083-9 specifications (DVB Blue Book A010 Rev.1)

> Four independent TX (ingress) channels supporting both 188 and 204 byte transport packet (TP) lengths (automatic adaptation), adopting for TP alignment the method proposed in subclause 5.2.1 of Technical Report ETSI TR 101 290 (five consecutive correct synch bytes for synch acquisition; two or more consecutive corrupted synch bytes should indicate synch loss, LOF) so accepting the presence of the inverted MPEG-x synch byte (i.e. 0xB8) according to DVB framing structure for cable systems (inverted synch byte is transparently transmitted)

> Four independent TX (ingress) channels supporting both “contiguous data packet” and “distributed data packet” transmission formats and having an ASI receiving buffer size of at least one 204 byte TP buffer each, according to ETSI TR 101 891 (DVB Blue Book A055)

> Four independent RX (egress) channels requiring an ASI receiving buffer size of at least one 204 byte TP buffer to receiving equipment, according to ETSI TR 101 891 (DVB Blue Book A055)

> Contiguous data packet (default) or distributed data packet output transmission formats, individually selectable by means of on-board switches

> Maximum differential delay compensation among VCs belonging to the same VCG of up to 48 ms

> Node latency lower than 20ms (not considering latencies due to distances, intermediate nodes, radio links, etc.)
