The present document is a specification of the lower layers and the lower layer signalling system for the two-way 
satellite network variants defined by ETSI TS 101 545-3 [i.16]. The present document constitutes a complete 
specification of the lower layers for a transparent star satellite network, a transparent mesh overlay satellite network and 
a regenerative re-multiplexing satellite network. Also, components required for a satellite network with a TRANSEC 
system are included. 
The present document is normative for the consumer terminal profile in a transparent star satellite network as defined 
by ETSI TS 101 545-3 [i.16], and does also include normative components specific to the other terminal profiles and 
satellite network variants defined by ETSI TS 101 545-3 [i.16].
