Note:
When MUX card mode (SW03-4 ON), only MUX and CFT functions are valid. MUX 1 is used for a con-
nection to TSW (Don’t use MUX 2, 3). The LED of MUXACT, M0SY, CFT, and PMCA are valid, other LED
is not lit. In the case of this mode, only SW03 is valid.

6. External Interface
When this circuit card is used in “clock subordinate office”, clock signals from DTI, CCT, PRT must be
extracted. See Figure 2-52 for more information. When this circuit card is used in “clock source office”
cable connections are not necessary.

1. General Function
This circuit card provides the Time Division Switch (TSW) and INT function for the system. Each TSW
card is capable of 8192 × 2048 Time Slot (TS) switching for an Interface Module Group (IMG). Four cards
allow 8192 × 8192 TS switching for the 4 IMG configuration.
The INT is an intermediate circuit of the CPR which controls and administrates the Port Microprocessor
(PM) for line/trunk...
