Check the reception and sending of variable length messages on the activated linkset from/to the SP at the other end of this linkset (and, in case of VAT, from/to other SP crossing the SP at the other end of this linkset). 3. Check that, after the alignment, the level 2 does not send any message received before or during the deactivation. 4. Check that all messages are correctly received (no loss of messages, no duplication and no missequencing). 5. Stop traffic. Fascicle VI.9 - Rec. Q.782 PAGE251 6.

Q.782 PAGE251 :Stop traffic Note - This test describes the activation of a linkset. The signalling link activation order is given simultaneously to all signalling links of the signalling linkset (Q.704 S 12.2.4.1). However, depending on in which order the links are getting aligned, changeback procedures will be performed. This test does not describe the transitory states (changeback procedure is checked in other tests). TEST DESCRIPTION 1. Check that the signalling links become available and start traffic between A and B (and A and C in VAT). 2. Check the reception and sending of variable length messages on the activated linkset from/to the SP at the other end of this linkset (and, in case of VAT, from/to other SP crossing the SP at the other end of this linkset). 3. Check that, after the alignment, the level 2 does not send any message received before or during the deactivation. 4. Check that all messages are correctly received (no loss of messages, no duplication and no missequencing). 5. Stop traffic.
