The present document should be read in conjunction with the normative document [i.2] in order to assist network operators, systems integrators, and equipment manufacturers in the realization of satellite based interactive services. The present document should be interpreted as recommendations or good practices but not as mandatory requirements. It is anticipated however that future procurement documents may reference elements of the present document as part of their system specification.The present document is applicable to satellite systems as defined in [i.2]. In such a system the RCSTs receive a Forward Link signal based on the DVB-S [i.1] or DVB-S2 [i.38] specifications. In a non-regenerative system, the Return Link signal transmitted from the RCST is received by one or more Gateways, which also interact with the NCC. In regenerative systems as well as in transparent mesh systems, it can be possible to also have direct RCST-to-RCST communications.The system as defined in [i.2] may be used in all frequency bands allocated to FSS or BSS services, and the first expected implementations are in the bands listed in annex E.Information concerning the most relevant international regulations and recommendations (ITU, ETSI, DVB, etc.) which could be applicable to the DVB-RCS terminals is included in clause 2.The present document, as well as the normative document [i.2], cover two RCST profiles:Type A, which is able to support IP services only. This type of terminal supports two types of data encapsulation, based on ATM or MPEG2.Type B, which is able to operate as RCST Type A and also to support native ATM protocols by encapsulating ATM cells within an MPEG2 Transport Stream on the forward link.The present document should not be used to justify the fulfilment of the essential requirements under article 3.2 of the R&TTE Directive [i.33]. Requirements for ElectroMagnetic Compatibility (EMC) under article 3.1b of the R&TTE Directive [i.33] are given in EN 300 673 [i.30] or EN 301 489-12 [i.31]. Harmful interference is limited by requiring a minimum set of Control and Monitoring Functions (CMF) as well as specifying limits for on-axis radiation, off-axis spurious radiation, carrier suppression, off-axis EIRP emission density and pointing accuracy. These specifications are in general depending on the transmit frequency. For system transmitting at Ku band frequencies EN 301 428 [i.9] applies. Limits for Ka band systems are given in EN 301 459 [i.8].Within the constraints of the above clause, there are a number of parameters that need to be declared by manufacturers and network operators for interoperability, including:All parameters defined in the CSC burst.Frequency plan, including frequency bands, of forward and return links.Range of symbol rate on forward and return link.Transmit and receive RF characteristics of the RCST, including at least: EIRP capability, frequency hopping capability, uplink power control capability, isolation between Tx and Rx and G/T.
