<p>Path protection in a TST cross connect is implemented in such way that less than half of the capacity is selected as the number of signals to be connected at the front end in the transmission direction. The signal to be path-protected is duplicated in the first time switch through the software, after which each of the duplicated signals (W, P) is routed through the TST using an ordinary TST routing algorithm for discrete signals. At the receiving end, both signals (W, P) are routed separately through the TS portion up to the last time switch, in which a selection is made through the software.</p> |
