Initial Conditions
System Simulator:
The SS is configured to use default RLP parameters.
Mobile Station:
The MS is configured to use RLP default parameters except the window size from MS to IWF (SS), called Kmi.
A non transparent data call will be established, so that the MS is in call state U10 ("Call Active").
Since some RLP parameters are different from the default parameters, a negotiation procedure will be initiated by the MS after the CONNECKT ACKNOWLEDGE message. The MS may negotiate the RLP default parameters within allowed ranges, defined in 3GPP TS 04.22, except the window size from MS to IWF (SS), called Kmi, which has to be a non default value.
The SS shall accept and use the new RLP parameters till the end of the test.
After the negotiation procedure the ABM will be entered. This test is repeated twice with 2 different values of Kmi, randomly chosen.
Procedure
The MS is made to send continuously I+S frames with a delay inferior to T1 between each frame.
The SS does not acknowledge the received I+S frames in RR frames.
The MS stops sending I+S frames after having sent Kmi frames without acknowledgement, due to the window size.
At the expiry of T1 after the last sending I+S frame, the MS shall send a supervisory command RR frame with P bit set to 1.
The SS answer in a RR response frame with F bit set to 1 and acknowledging j<Kmi frames (j is randomly chosen).
The MS shall retransmit the Kmi-j lost I+S frames and then shall continue to send I+S frames.
The SS acknowledges the received I+S frames in RR frames.
The MS is returned to the idle state by clearing of the call.

29.3.2.6.7.1 Definition
|
The last frame of a sequence of numbered information frames is guarded by timer T1. Failure to receive an acknowledgement, or a reject, within a time T1, shall result in the RLP entity starting a checkpoint recovery procedure. If the RLP peer entity fails to respond to a checkpoint command, which is also guarded by timer T1, the checkpoint recovery procedure shall be repeated, up to N2 times.

|
Initial Conditions
System Simulator:
The SS is configured to use default RLP parameters.
Mobile Station:
If possible, the MS is configured to use RLP default parameters except the number of retransmission N2. If a MS cannot be configured to use a non default N2 value, the SS shall use XID negotiation to modify the value of N2 to be used during the test.
A non transparent data call will be established, so that the MS is in call state U10 ("Call Active").
Since some RLP parameters are different from the default parameters, a negotiation procedure will be initiated by the MS after the CONNECKT ACKNOWLEDGE message. The MS may negotiate the RLP default parameters within allowed ranges, defined in 3GPP TS 04.22, except the number of retransmission N2, which has to be a non default value.
The SS shall accept and use the new RLP parameters till the end of the test.
After the negotiation procedure the ABM will be entered.
Once in ABM, the SS shall initiate the transmission of an I+S frame, which will transfer L2RCOP status information between peer L2RCOP entities (SS to MS). The MS may respond with an I+S frame containing L2RCOP status information. The SS shall be capable of initiating this sequence, or responding to an I+S L2RCOP status frame from the MS.
This test is repeated twice with 2 different values of N2, randomly chosen.
Test Procedure
The MS is made to send only one I+S frames.
The SS does not acknowledge the received I+S frame.
At the expiry of T1 after the sending of the I+S frame, the MS shall send a supervisory command RR frame with P bit set to 1.
The SS answer in a RR response frame with F bit set to 0 and N(R) acknowledging the I+S frame sent by the MS.
At the expiry of T1 after the sending of the frame with P=1, the MS shall send a new supervisory command RR frame with P bit set to 1.
The SS answer in a RR response frame with F bit set to 0 and N(R) corresponding to the I+S frame sent by the MS.
These 2 last steps are repeated N2 times.
At the expiry of T1 after the sending of the frame with P=1, the MS shall reset (SABM) or disconnect (DISC) the link.
The SS answer with an UA frame.
The MS is returned to the idle state by clearing of the call.

Initial Conditions
System Simulator:
The SS is configured to use default RLP parameters.
Mobile Station:
The MS is configured to use RLP default parameters. The window size from IWF (SS) to MS is called KIM.
The MS is made to establish a MO non transparent data call. In initial conditions MS is in call state U10 ("Call Active") after having sent a CONN_ACK message.
Case a: No negotiation will be initiated by the MS.
Case b: The MS initiates negotiation of RLP default parameters.
NOTE: The MS is allowed to initiate the negotiation of the RLP default parameters, within allowed ranges, defined in 3GPP TS 04.22. The MS shall do this in the ADM, after having sent a CONNECT ACKNOWLEDGE message (MO-case) or after having received a CONNECT ACKNOWLEDGE message from the SS (MT-case.)
Specific PICS statements:
-
PIXIT statements:
• Bearer services supported
• Characteristics of non-transparent services.
Foreseen final state of the MS
Idle.
Test procedure
Case 1: Testing of the correct handling of the MS to a received XID frame in ADM
Immediately after having received the "CONN_ACK", the SS sends a correct XID frame containing randomly chosen parameters different from the default parameters and supported by the MS.
If the MS initiates a negotiation procedure, before the SS is able to transmit the XID frame (timing conflict), the SS should accept this - XID frame from the MS and start his own negotiation afterwards.
The MS shall respond with a XID frame. If parameters sent in this frame are different from those chosen by the SS, the correct sense of negotiation is checked. The final parameters are noted (T1, T2, N2, KIM (window IWF (SS) -> MS), KMI (window MS -> IWF (SS))).
The MS sends a SABM and the SS answers with an UA. Note: the SABM frame may be sent by the MS before the XID response frame. In such a case, the SS waits for the XID response before sending the UA.
Case 2: Testing of the correct handling of the MS to a received XID frame in ABM
The MS sends a SABM and the SS answer with an UA.
The SS sends a correct XID frame containing parameters different from the default parameters and supported by the MS.
The MS shall respond with a XID frame. If parameters sent in this frame are different from those chosen by the SS, the correct sense of negotiation is checked. The final parameters are noted (T1, T2, N2, KIM (window IWF (SS) -> MS), KMI (window MS -> IWF (SS))).
The SS checks that the MS uses the new parameters determined during the negotiation procedure.
Verification of T2
After optional status bits exchange between the MS and the SS, the SS is configured to send I+S frames with a delay inferior to T1 between each frame. The MS is made to send no user data, it sends only supervisory frame.
The SS sends an I+S frame numbered N(S)=NSS mod(62), the MS shall acknowledge this frame within T2.
Verification of KIM
The SS sends an I+S frame numbered NSS+KIM+1 mod(62). The MS shall ignore this frame (out of the window), it shall not acknowledge or reject it. This is checked during at least T2.
The SS sends an I+S frame numbered N(S)=NSS+1 mod(62), the MS shall acknowledge this frame.
The SS sends an I+S frame numbered NSS+KIM+1 mod(62). The MS shall reject all the lost frames numbered NSS+2 mod(62) to NSS+KIM mod(62). It shall send a REJ or SREJ frame with N(R)=NSS+2 mod(62).
If REJ frame is used by the MS, the SS restarts the transmission of I+S frames from frame numbered NSS+2 mod(62). The MS shall acknowledge these frames. After having sent at least the frame numbered NSS+KIM+2 mod(62), the SS stops sending I+S frames.
If SREJ frame is used by the MS, the SS restarts the transmission of I+S frames from frame numbered NSS+2 mod(62). It does send the frame numbered NSS+KIM+1 mod(62) a second time. The MS shall acknowledge these frames. After having sent at least the frame numbered NSS+KIM+2 mod(62), the SS stops sending I+S frames.
Verification of KMI
The MS is now configured to send continuously I+S frames with a delay inferior to T1 between each frame.
The MS sends I+S frames, the SS does not acknowledge these frames.
After having sent KMI I+S frames, the MS shall stop sending I+S frames (end of the window).
Verification of T1
At the expiry of T1 after the last I+S frame, the MS shall enter in "checkpoint recovery" mode, it shall send a supervisory RR frame with C=1 and P=1.
The SS does not answer to checkpointing.
Verification of N2
At the expiry of T1 after the last RR (C=1, P=1) frame, the MS shall resend a supervisory RR frame with C=1 and P=1. The SS does not answer to checkpointing. This is repeated N2 times.
After N2 retransmissions of the same RR frame (C=1, P=1), The MS shall reset or disconnect the RLP link by sending a SABM (C=1,P=1) or a DISC (C=1) frame. The SS answers with an UA (R=0) frame with F bit set to P bit received in SABM or DISC frame.
The MS is returned to the idle state by clearing of the call.
The test is performed for case 1 and 2.
Maximum duration of test

Initial Conditions
System Simulator:
The SS is configured to use default RLP parameters.
Mobile Station:
The MS is configured to use RLP arbitrary chosen parameters different from the default parameters.
1. The MS is made to establish a MO non transparent data call. In initial conditions MS is in call state U10 ("Call Active") after having sent a CONN_ACK message.
2. The MS is made to establish a MT non transparent data call. In initial conditions MS is in call state U10 ("Call Active") after having received a CONN_ACK message.
This test is performed for initial conditions 1 and 2.
Once in ABM, the SS shall initiate the transmission of an I+S frame, which will transfer L2RCOP status information between peer L2RCOP entities (SS to MS). The MS may respond with an I+S frame containing L2RCOP status information. The SS shall be capable of initiating this sequence, or responding to an I+S L2RCOP status frame from the MS.
Specific PICS statements:
•
PIXIT statements:
• Bearer services supported
• Characteristics of non-transparent services.
Foreseen final state of the MS
Idle.
Test procedure
The MS shall send an XID (C=1, P=1) frame containing a set of RLP parameters different from the default set. The SS answers with XID (R=0, F=1) containing new parameters randomly chosen, the sense of negotiation is correct. Optionally, a renegotiation initiated by the MS should be possible, if the parameters, randomly chosen by the SS are not supported by the MS. In this case, the SS should accept the parameters renegotiated by the MS, if they are within the allowed range defined in 3GPP TS 04.22. The final parameters are noted (T1, T2, N2, KIM (window IWF (SS) -> MS), KMI (window MS -> IWF (SS))).
The MS established the ABM mode by sending a SABM (C=1, P=1) frame. The SS answers with a UA (R=0, F=1) frame. The SABM frame may be sent by the MS before the XID. In such a case, the SS answers to the XID after having established the ABM mode (i.e. after having sent the UA).
The SS checks that the MS uses the new parameters determined during the negotiation procedure.
Verification of T2:
The SS is configured to send I+S frames with a delay inferior to T1 between each frame. The MS is made to send no user data, it sends only supervisory frame.
The SS sends an I+S frame numbered N(S)=NSS mod(62), the MS shall acknowledge this frame within T2.
Verification of KIM:
The SS sends an I+S frame numbered NSS+KIM+1 mod(62). The MS shall ignore this frame (out of the window), it shall not acknowledge or reject it. This is checked during at least T2.
The SS sends an I+S frame numbered N(S)=NSS+1 mod(62), the MS shall acknowledge this frame.
The SS sends an I+S frame numbered NSS+KIM+1 mod(62). The MS shall reject all the lost frames numbered NSS+2 mod(62) to NSS+KIM mod(62). It shall send a REJ or SREJ frame with N(R)=NSS+2 mod(62)
If REJ frame is used by the MS, the SS restarts the transmission of I+S frames from frame numbered NSS+2 mod(62). The MS shall acknowledge these frames. After having sent at least the frame numbered NSS+KIM+2 mod(62), the SS stops sending I+S frames.
If SREJ frame is used by the MS, the SS restarts the transmission of I+S frames from frame numbered NSS+2 mod(62). It does send the frame numbered NSS+KIM+1 mod(62) a second time. The MS shall acknowledge these frames. After having sent at least the frame numbered NSS+KIM+2 mod(62), the SS stops sending I+S frames.
Verification of KMI:
The MS is now configured to send continuously I+S frames with a delay inferior to T1 between each frame.
The MS sends I+S frames, the SS does not acknowledge these frames.
After having sent KMI I+S frames, the MS shall stop sending I+S frames (end of the window).
Verification of T1:
At the expiry of T1 after the last I+S frame, the MS shall enter in "checkpoint recovery" mode, it shall send a supervisory RR frame with C=1 and P=1.
The SS does not answer to checkpointing.
Verification of N2:
At the expiry of T1 after the last RR (C=1, P=1) frame, the MS shall resend a supervisory RR frame with C=1 and P=1. The SS does not answer to checkpointing. This is repeated N2 times.
After N2 retransmissions of the same RR frame (C=1, P=1), The MS shall reset or disconnect the RLP link by sending a SABM (C=1,P=1) or a DISC (C=1) frame. The SS answers with an UA (R=0) frame with F bit set to P bit received in SABM or DISC frame.
The MS is returned to the idle state by clearing of the call.

Test procedure
The MS shall send an XID (C=1, P=1) frame containing a set of RLP parameters different from the default set. The SS sends a XID (C=1, P=1) command frame containing new parameters. After a delay the MS shall resend the same XID that it has previously sent. The SS answers with XID (R=0, F=1) accepting the parameters chosen by the MS. These parameters are noted (T1, T2, N2, KIM (window IWF (SS) -> MS), KMI (window MS -> IWF (SS))).
The MS established the ABM mode by sending a SABM (C=1, P=1) frame. The SS answers with a UA (R=0, F=1) frame. The SABM frame may be sent by the MS at any instant (i.e. just after having received an XID, before having sent the response). In such a case, the SS answers to the XID after having established the ABM mode (i.e. after having sent the UA).
The SS checks that the MS uses the new parameters determined during the negotiation procedure.
Verification of T2:
The SS is configured to send I+S frames with a delay inferior to T1 between each frame. The MS is made to send no user data, it sends only supervisory frame.
The SS sends an I+S frame numbered N(S)=NSS mod(62), the MS shall acknowledge this frame within T2.
Verification of KIM:
The SS sends an I+S frame numbered NSS+KIM+1 mod(62). The MS shall ignore this frame (out of the window), it shall not acknowledge or reject it. This is checked during at least T2.
The SS sends an I+S frame numbered N(S)=NSS+1 mod(62), the MS shall acknowledge this frame.
The SS sends an I+S frame numbered NSS+KIM+1 mod(62). The MS shall reject all the lost frames numbered NSS+2 mod(62) to NSS+KIM mod(62). It shall send a REJ or SREJ frame with N(R)=NSS+2 mod(62).
If REJ frame is used by the MS, the SS restarts the transmission of I+S frames from frame numbered NSS+2 mod(62). The MS shall acknowledge these frames. After having sent at least the frame numbered NSS+KIM+2 mod(62), the SS stops sending I+S frames.
If SREJ frame is used by the MS, the SS restarts the transmission of I+S frames from frame numbered NSS+2 mod(62). It does send the frame numbered NSS+KIM+1 mod(62) a second time. The MS shall acknowledge these frames. After having sent at least the frame numbered NSS+KIM+2 mod(62), the SS stops sending I+S frames.
Verification of KMI:
The MS is now configured to send continuously I+S frames with a delay inferior to T1 between each frame.
The MS sends I+S frames, the SS does not acknowledge these frames.
After having sent KMI I+S frames, the MS shall stop sending I+S frames (end of the window).
Verification of T1:
At the expiry of T1 after the last I+S frame, the MS shall enter in "checkpoint recovery" mode, it shall send a supervisory RR frame with C=1 and P=1.
The SS does not answer to checkpointing.
Verification of N2:
At the expiry of T1 after the last RR (C=1, P=1) frame, the MS shall resend a supervisory RR frame with C=1 and P=1. The SS does not answer to checkpointing. This is repeated N2 times.
After N2 retransmissions of the same RR frame (C=1, P=1), The MS shall reset or disconnect the RLP link by sending a SABM (C=1,P=1) or a DISC (C=1) frame. The SS answers with an UA (R=0) frame with F bit set to P bit received in SABM or DISC frame.

Initial Conditions
System Simulator:
The SS is configured to use default RLP parameters.
Mobile Station:
The MS is configured to use RLP parameters different from the default parameters (T1 different from T1(def)).
The MS is made to establish a MO non transparent data call. In initial conditions MS is in call state U10 ("Call Active") after having sent a CONN_ACK message.
Specific PICS statements:
-
PIXIT statements:
• Bearer services supported
• Characteristics of non-transparent services.
Foreseen final state of the MS
Idle.
Test procedure
The MS shall send an XID (C=1, P=1) frame containing a set of RLP parameters different from the default set. The SS sends a XID (R=0, F=0) command frame. The MS shall ignores this frame.
After a delay the MS shall resend the same XID that it has previously sent. The SS does not answer.
After a delay the MS shall resend the same XID that it has previously sent. The SS answers with XID (R=0, F=1) accepting the parameters chosen by the MS.
The MS established the ABM mode by sending a SABM (C=1, P=1) frame. The answer with a UA (R=0, F=1) frame. The SABM frame may be sent by the MS at any instant (i.e. just after having received an XID). In such a case, the SS answers to the XID after having established the ABM mode (i.e. after having sent the UA).
The MS is returned to the idle state by clearing of the call.
Maximum duration of test
1 minute.

29.4.1 General
|
According to ITU-T Recommendation T.30 a facsimile call can be divided into the following phases:
- Phase A - call establishment procedure;
- Phase B - pre-message procedure (identification and selection of required facilities);
- Phase C - message transmission according to ITU-T Recommendation T.4;
- Phase D - post-message procedure;
- Phase E - call release procedure.
For each phase a single test sequence was drafted, i.e. the verification of the basic procedures of a fax call will at least consist of 5 tests, in order to verify the above described phases.
In the IDLE state the fax adapter, originating or terminating, will send continuously SYNC frames containing the pattern specified in 3GPP TS 03.45 (CT105 (see note 2) and 109 (see note 2) are in OFF condition).
For the test of the facsimile data transmission, i.e. the phase C, test chart #2 according to ITU-T Recommendation T.21 should be used.
The T.4/30 messages marked with the '*' sign indicate that for the transmission across the radio interface in case of the BCS phase STATUS frames are used, and in case of the message phase the usage of DATA frames is implied.
Manufacturer-declared fax equipment should be connected to the MS, i.e. where possible a fax adapter and a fax machine Group 3. Measuring devices to monitor the T.4/T.30 protocol, the circuits and the SYNC, STATUS and DATA frames should be provided. Configurations, where no access to the interfaces to monitor the protocol and circuits is possible, might exist.

Initial conditions
A TS 61 s/f call is set up. The speech phase is active.
Test procedure
The transition from speech to fax is initiated by manual intervention at both ends of the connection. The data call direction DCD is mobile originated. Upon connection to line the FA turns on CT108.2 (see note 2) as a basic requirement for the transition from speech to fax. Now, within the next 3 seconds the FA has to detect the DCD, which is in this case is mobile originated, i.e. CT105 is set to ON (see note 2) condition. The following ICM procedure via the MODIFY message is carried out by the MT 3 seconds after circuit CT108.2 was set to ON (see note 2) condition. On completion of the ICM procedure the synchronization of the TCH begins and after its completion the MT has to set CT107 to ON (see note 2) condition and the FA has to send the CED tone (see note 2) towards the connected fax. When CT106/109 are set to ON (see note 2) phase A is completed. Then the call is cleared by manual intervention at the MT or the activity progress of the call proceeds to the next phase.

Initial conditions
The MS, configured for the TS 62 fax call, is updated. Then the call establishment phase A begins.
Test procedure
The FA sets CT108.2 to ON (see note 2) condition and passes the dialling information to the MT. A SETUP message is then sent by the MT towards the SS. When the TCH is available (indicated by the CONNECT message) the synchronization phase begins, i.e. both entities start sending the synchronization pattern 1/OFF. CT106, 107, 109 have to be in OFF condition (see note 2). Upon completion of the synchronization phase the MT sets CT107 to ON condition (see note 2) causing the FA to connect the fax to line. The SS sets CT106 and CT109 to ON at the MT by means of the V.110 X and SB bits. The FA then generates the CED tone (see note 2), which completes phase A. Then the call is cleared by manual intervention at the MT or the activity progress of the call proceeds to the next phase.

Initial conditions
The activity progress of the fax call is brought to the beginning of Phase B.
Test procedure
After phase A the FA is in BCS-TRA state and sends SYNC frames. The SS being in BCS-REC state sends the T.30 DIS embedded in STATUS frames indicating its capabilities. The received DIS is checked, if necessary edited by the FA and sent to the fax. Then the FA returns to the idle state. The fax checks whether the indicated capabilities are in line with its own or not, and chooses the capabilities which are supported end-to-end by the connected fax machines by answering with the DCS frame preceded by the preamble. The FA enters the BCS-REC state and the BCS information is transmitted using the STATUS frames. Afterwards the FA returns to the idle state. Upon reception of the training sequence the FA enters the MSG-REC state without waiting for an acknowledge from the SS, i.e. the TCF is conveyed by means of the DATA frames. The FA enters the idle state and sends at least 5 SYNC frames to indicate that the message phase is over. Then the CFR frame is received, i.e. the FA enters the BCS-TRA state and receives the CFR in STATUS frames. Now, phase B is completed and the data transfer phase C begins. Then the call is cleared by manual intervention at the MT or the activity progress of the call proceeds to the next phase.

Initial conditions
The activity progress of the fax call is brought to the beginning of Phase C. The ECM shall not be used.
Test procedure
The FA is in IDLE state. The connected fax starts transmitting the fax message. Upon reception of the training sequence the FA enters the MSG-REC state and sends STATUS frames, which contain the ident octet set to MSG-REC, interleaved with SYNC frames to the SS. When the SS has entered the MSG-TRA state, which is indicated to the FA by means of the ident octet set to MSG-TRA, the FA starts sending the fax coded data (received from the connected fax) embedded in DATA frames. When the transmission is finished the FA is again in the idle state for at least 5 SYNC frames to indicate that the message phase is over and Phase D begins. Then the call is cleared by manual intervention at the MT or the activity progress of the call proceeds to the next phase.

Initial conditions
The activity progress of the fax call is brought to the beginning of Phase D. The ECM shall not be used.
Test procedure
The fax sends the preamble followed by the EOP frame. The FA then enters the BCS-REC state after having transmitted at least 5 SYNC frames since the last transition to the idle state and sends the EOP frame embedded in STATUS frames to the SS. The FA enters the idle state again. Upon detection of the BCS-REC identifier octet the BCS-TRA state is entered in order to receive the MCF frame issued by the SS. Then the preamble and the MCF frame are conveyed to the connected fax by the FA. The FA enters the idle state. Phase D of the fax transmission is completed. Then the call is cleared by manual intervention at the MT or the activity progress of the call proceeds to the next phase.

1. To be verified that the FA enters the BCS-REC state and inserts the correct ident octet in the STATUS frames. The up-conversion to the message speed has to be checked.. The condition of CT109 has to be verified (see note 2). The contents of the SYNC frames shall be checked.
2. To be verified that the FA enters the BCS-TRA state upon detection of the BCS-REC identifier and that the correct T.30 message is conveyed to the connected fax machine (down-conversion to the BCS speed). The condition of CT105 should be checked (see note 2).

|
Initial conditions
The activity progress of the fax call is brought to the beginning of Phase E.
Test procedure
The fax sends the preamble followed by the DCN frame. The FA then enters the BCS-REC state and sends the DCN frame embedded in STATUS frames to the SS. The FA enters the IDLE state again. CT108.2 will go OFF condition (see note 2) and after 200ms CT109 will go to OFF condition (see note 2) too. The MT then sends the DISC message and the call is cleared.
