This document specifies the requirements for a protocol derived from HCI/HCP (see ETSI TS 102 622) enabling communication for devices regardless of data link and physical layers. This document covers the following: a) outline of a system comprised of one or more hosts and one controller; b) extension of connection topology between hosts and host controller (i.e. star topology and additional other topologies); c) segregation between existing system using ETSI TS102 613 and new system compliant to this document (this document refers ETSI TS 102 613, but does not change its specification and does not use RFU). For ETSI TS 102 622, data link layer and physical layer like SWP specified in ETSI TS 102 613 is out of the scope. Albeit questioned in this document, the duplication of OSI transport layer by e.g. enforcing encapsulation of HCP into T=1 or the reverse, is out of the scope.

Introduction
This document is laid on the ground of ISO/IEC 7816 (all parts) specifying integrated circuit cards and
the use of such cards for interchange, and on ETSI TS 102 622 defining the HCI core that is an application
independent logical interface.
ETSI TS 102 622 is referenced in this document as a well-known HCI specification, however it should
be noted ETSI TS 102 622 describes another host network with the host controller implemented by
the CLF/NFC controller and with hosts residing on UICCs/SEs all connected to the host controller.
ETSI TS 102 622 allows for other interfaces than SWP for data link layer of HCI, and does not mandate
using the SWP but just describes the condition if the SWP is used.

1 Scope
This document specifies the requirements for a protocol derived from HCI/HCP (see ETSI TS 102 622)
enabling communication for devices regardless of data link and physical layers. This document covers
the following:
a) outline of a system comprised of one or more hosts and one controller;
b) extension of connection topology between hosts and host controller (i.e. star topology and
additional other topologies);
c) segregation between existing system using ETSI TS 102 613 and new system compliant to this
document (this document refers ETSI TS 102 613, but does not change its specification and does not
use RFU).
For ETSI TS 102 622, data link layer and physical layer like SWP specified in ETSI TS 102 613 is out of
the scope.
Albeit questioned in this document, the duplication of OSI transport layer by e.g. enforcing encapsulation
of HCP into T=1 or the reverse, is out of the scope.
