5.11.1. General 
The ECMA1 QSIG protocol is based on the European ETSI standard (see
Figure 20).
A variation of supplementary services supporting the ETSI standard was
implemented and tested (see Table 7).
In the meantime, the European Standardization Committee ETSI has released
edition 2 (following the ISO standard). The coding of the ETSI edition
1 supplementary services implemented is not compatible with ETSI edition
2 (see Table 6).
A new protocol variant ECMAV2 was incorporated with the same feature
range as the predecessor (see Figure 20).
The worldwide accepted standardization committee ISO/IEC (International
Standardization Organization/International Electrotechnical Commission)
included the QSIG standard in the standards catalogue. The coding of
the ETSI edition 1supplementary services is not compatible with ISO/IEC
edition 1. Consequently, a new protocol (PSS1V2) was incorporated with
the same features as the predecessor (see Figure 20).
The QSIG protocol "CorNet NQ V2.1/V2.2/V2.3" describes private signaling
based on the ISO standard on one hand, and signaling based on the ETSI
standard's Basic Call (edition 3) and Supplementary Services (edition
2) on the other.
IMPORTANT:
The private CorNet N elements are no longer transferred
in the protocol. This means that the CorNet-N-specific features no longer
work.
Use the ECMA1 protocol variant to network Hicom 300 E V2.0 with an
OpenScape 4000.
CORNV33 is available for coupling an OpenScape 4000 to CorNet N networks
with Hicom 300 V3.3.
A comparison of the various releases is required for the correct use
of the protocol variants (ECMA1, PSS1V2 and ECMAV2) for networking an
OpenScape 4000 with a third-party PINX (see Table 6).
The continuity of the individual features on the reference points
S/T and Q over the various protocols is shown in Table 7.
