Slot No. Circuit Card Symbol Functions, Mounting Conditions

00, 01 PH-PW14 PWRSW This circuit card supplies operating power to circuit cards accommodated

in the TSWM.

08, 09 PH-PC20 DLKC This circuit card provides the Attendant Consoles (ATTs) with

information such as ATT call termination/answer/release (abandoned

call) via the Data Link which is established in the TSW card. In addition,

station idle/busy information is sent to the ATTs via the same Data Link.

10, 11 PH-GT09 GT This circuit card permits the CPU to directly control the TSW, PLO,

DLKC, and MISC circuit cards via TSW I/O Bus and MISC I/O Bus.

12-19 PH-SW12 TSW This circuit card supplies the Time Division Switch (TSW) and INT

function for the system. The TSW capacity is 8192 × 2048 TS (time slots)

for an IMG, and 4 cards achieves 8192 × 8192 TS switching for Multiple

IMG configuration.

21, 23 PH-CK16 PLO This circuit card, used with a digital interface circuit card, sets up network

synchronization. With this circuit card, the IPX Multiple IMG system can

be a clock subordinate office of the digital network.

21, 23 PH-CK17 PLO This circuit card, used with a digital interface circuit card, sets up network

synchronization. Since this circuit card provides high precision base

clock oscillator, the IPX Multiple IMG system can be a clock source

office of the digital network.
