Aion Online’s Stigma System Explained

Principle

The Digital Space Switch consists of several input highways, X1, X2,…Xn and several output highways, Y1, Y2,………….Ym, inter connected by a crosspoint matrix of n rows and m columns. The individual crosspoint consists of electronic AND gates. The operation of an appropriate crosspoint connects any channel, a, of I/C PCM highway to the same channel, a, of O/G PCM highway, during each appropriate time-slot which occurs once per frame as shown in Fig 2. During other time-slots, the same crosspoint may be used to connect other channels. This crosspoint matrix works as a normal space divided matrix with full availability between incoming and outgoing highways during each time-slot.

Each crosspoint column, associated with one O/G highway, is assigned a column of control memory. The control memory has as many words as there are time-slot per frame situs slot terpercaya in the PCM signal. In practice, this number could range from 32 to 1024. Each crosspoint in the column is assigned a binary address, so that only one crosspoint per column is closed during each time-slot. The binary addresses are stored in the control memory, in the order of time-slots. The word size of the control memory is x bits, so that 2x = n, where n is the number of crosspoints in each column.

A new word is read from the control memory during each time-slot, in a

Cyclic order. Each word is read during its corresponding time-slot, i.e.,

Word 0 (corresponding to TSO), followed by word 1 (corresponding to TS1) and so on. The word contents are contained on the vertical address lines for the duration of the time-slot. Thus, the crosspoint corresponding to the address, is operated during a particular time-slot. This crosspoint operates every time the particular time-slot appears at the inlet. in successive frames. normally, a call may last for around a million frames.

As the next time-slot follows, the control memory is also advanced by one step, so that during each new time-slot new corresponding words are read from the various control memory columns. This results in operation of a completely different set of crosspoints being activated in different columns. Depending upon the number of time-slots in one frame, this time division action increases the utilisation of crosspoint 32 to 1024 times compared with that of conventional space-divided switch matrix.
