Notes : 1. SPVALis active in V.33receiver only at the same time as the rising transition of the SCR1s signal. When SPVALis set, it
indicates that the SPEEDbits contain the Data speed information.
2. SPEED is valid in V.32bis,V.32,V.22bis, V.22, Bell 212Aand V.33receiver only with the following meaning :

3. The STAOP2 Bit reflects the progression of the Synchronisation.
4. Only valid in V.21Channel 2 Receive mode.
5. SPVALis active in V.32bis/V.32/V.22bis/V.22at the end of the training sequence and at least 8 baud before entering Data mode.
SPVALand SPEED are also updated with each retrain and rate negotiation.
6. The SPAOP1 bitsreflect the progressionof the synchronization in Data modes.
