    2 Certification Profile Level 1-A

    Requirements

    Certification Profile Level 1a requirements are organized into the following categories:

    ? General Requirements related to the ITU-T H.323 v2 standard and requirements supporting interoperability

    in a single zone

    ? Component-specific requirements related to terminals, gateways, MCUs and gatekeepers

    ? General service requirements related to voice, video, modem, Fax, DTMF requirements

    # Requirement 1References

     Basic Protocol Requirements

     Components shall comply with all mandatory aspects of H323V2.

     Endpoints and Gatekeepers shall support all mandatory RAS messages.

     Endpoints and Gatekeepers shall use lightweight RRQs.

     Endpoints initiating faststart calls shall fallback to H.245 procedures (separate H.245

    logical channels), if faststart fails.

     Endpoints shall close Logical channel on receiving Empty(Null) Capability Set and

    reopen logical channels on receiving a subsequent non Null Capability Set.

     General Intra-Zone Requirements

     Endpoint Requirements

     Endpoints shall transparently forward tokens that are received in ACF to the Terminating endpoint in the H.225 setup message. Endpoints shall also transparently

    forward tokens received in the H.225 setup message in the answer call ARQ. Gatekeeper Requirements

     Gatekeepers shall transparently forward tokens received in the LCF message to the endpoint in the ACF message. Gatekeepers shall not reject any H.323 messages because of extraneous tokens.

     Endpoints (Terminals and Gateways)-Specific Requirements

     Endpoints shall be capable of encoding and decoding speech according to

    Recommendation G.711. (Reference ITU H.323 v2 section 6.2.5)

     Multipoint Control Unit-Specific Requirements

     Multipoint Control Units shall be capable of encoding and decoding speech according

    to Recommendation G.711. (Reference ITU H.323 v2 section 6.2.5)

     Gatekeeper-Specific Requirements

     Gatekeepers shall support LRQ for inter-zone communication.

     Gateway-specific requirements note that any entity which includes

    GW functionality should follow this requirements GWs shall transport all Q.931 Information Elements from call signaling messages on SCN to H.225 messages as defined by H.323 v2 (ex. Bearer capability, Called party

    number, calling party number, display, etc). GWs shall set and handle the Progress Indicator as defined in the Q.931 specification.

     GWs shall provide mapping of ReleaseCompleteReason to the Cause IE as specified

    in H.225v2 section 7.2.2.8. 63695042.doc H.323 Forum Certification Profile Level 1A Requirements 4 GWs shall forward all DTMF received from PSTN side onto H.323

    1 Noted as Standard Compliant (SC) or Beyond Existing Standards Scope (BESS).

side and vice-versa

     Video-Specific Requirements

     All video capable terminals shall be capable of encoding and decoding video according to H.261 QCIF T120-Specific requirements

     If data applications are supported Endpoints shall support the T.120 protocol.

     Modem-Specific Requirements

     If modem is supported Endpoints shall support modem pass-through by being able to

    detect modem tones and performing an upspeed to g711 codec.

     Fax-Specific Requirements

     If fax is supported Endpoints shall support the T.38 fax protocol using UDP (gateway requirement only) DTMF Requirements

     Endpoints shall support H.245 Alphanumeric out of band DTMF relay.
