TSW Card Replacement Procedure

TSW circuit card is located in the slot numbers, ranging from 06 to 13 within the TSWR. Equipped with

the Time Division Switch (TSW) and Speech Path Controlling Interface (INT), the card's main function

is to provide a maximum of 8192 2048 Time Slot (TS) switching for a designated single IMG. Because

a single TSW card only enables the TS switching associated with a single, individual IMG alone, note

that the fully expanded 4-IMG system requires a total of four TSW cards when it adopts a single

configuration, or as many as eight in the case of dual configuration. If your system adopts the latter's

dual configuration, the card's replacement procedures are as follows:

Figure 5-4 provides the system block diagram centering on the TSW cards. If the ACT/STBY of TSW

is changed over, that of DLKC and MUX in the same switching block are also totally changed over.
