PH-SW10
Time Division Switch
The PLO can output the clock signals (CLK) and the frame head signals (FH) as follows:
32.768 MHz CLK
8 KHz FH
5 m s ec × n FH (for wireless module ).
The MUX performs multiplexing/de-multiplexing of the 2 Mbps PC M highways running in PIM 0, and it
sends/receiv es the PCM to/from the TSW, and operates like the MUX card of PIM 1/2/3.
This circuit card includes the Digital Tone Generator (DTG) and hold tone (MUSIC) inserti on circuit. The
TONE ROM located on this circuit card contains the audible tone, and the hold tone is supplied from the
EMA card . In add i t ion , the desig n at ed time slot o f PC M (S p eech Path Memo ry : SPM ) can be i ns er ted as a
tone/music voice prompt. (For example, you can join the SPM and a DAT port by the nailed down
connection, and the DAT's voice prompt is given to the system instead of ordinary tone/music.)
Additionally, this circuit card supports the CFT (3-Party Conference) function and is equipped with eight
circuits of 3-Party Conference Trunk.
