TEST DESCRIPTION
1. Check that the signalling link becomes available.
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.

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.
