CHAPTER 2 Operations of SV8500 Server
[4-IMG]
To changeover the ACT/STBY of Speech Path System, the CMOD command is normally used.
However, if the command cannot be used, use the key operations listed below.
ACT/STBY of the Speech Path System can be changed over via the MBR key on the GT (PH-GT09)
card. Because each GT (GT 0 and GT 1) can control both the Speech Path System 0 and 1, perform the
key operation on the active GT card, not on the card in STBY mode.
By changing over the ACT/STBY of Speech Path System, all the related systems, such as TDSW,
DLKC, and MUX, are totally switched over.
Figure 2-14 System Block Diagram (Switching Network for Speech Path System)
Note 1:
When turning on and off the MBR key on the GT PKG, all the speech path (TSW/INT, DLKC, MUX)
will also be changed over.
