Multiplexer
The PCM highway running is illustrated in Figure 2-40. There are sixteen 2 Mbps PCM highways (HW0 -
HW15) in the PIM. Each PCM highway runs from a card slot to the MUX circuit card. For instance,
highway number zero (HW0) appears in Slot 04 and also Slot 05, thus the HW0 carries the PCM of the
Group number 0, 1, 2 and 3.
Likewise, the HW6, 7, 14, 15 cover the group numbers 24 through 31. However, the time slots of Group
number 24 and 25 are exclusively used for the Speech Path Memory (SPM).
All highways in the PIM lead to a MUX card, so 512 time slots (32 time slots per highway × 16 highways
= 512 time slots) of PCM are multiplexed/de-multiplexed at a MUX and sent/received to/from the TSW
circuit card across the 32.786 Mbps of the Low Voltage Differential Signaling (LVDS).
Also the MUX card provides the PM bus interface. The CPR controls and administrates the PM of the line/
trunk circuit card via the TSW and the MUX.
In addition, this circuit card supports 3-Party Conference (CFT) function and is equipped with eight circuits
of 3-Party Conference. The CFT appear in Time Slots 8 through 31 of the HW13 (Group 21 - 23).
