\ \(em\ 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 \(sc\ 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).

\ \(em\ The object of this test is to check the interface L2\(hyL3 by
invoking a changeover by the different means listed in Q.704 (\(sc 3.2.2). These reasons are: high error rate, expiration of timer T1, T2, T6 and T7 of L2,
equipement failure, erroneous BSN or FIB, reception of SIOS, SIN, SIE, SIO and SIPO of L2, and management request. The goal of this test is not to check the changeover procedure itself, but only that the COO is generated for each
of these reasons.
