To successfully execute the full stack of SS7 protocol layers, a TX board must be properly licensed. Certain extended link capabilities (such as the use of High Speed Links) also require specific board-based licensing. The following example shows a set of txalarm messages that indicate licensing-related startup failure conditions:
sigtran 2 16384 Cannot run task sigtran: board not licensed for full stack operation
isup 2 16384 Cannot run task isup: board not licensed for full stack operation
sccp 2 16384 Cannot run task sccp: board not licensed for full stack operation
tup 2 16384 Cannot run task tup: board not licensed for full stack operation
tcap 2 16384 Cannot run task tcap: board not licensed for full stack operation
