The TONE ROM located on this circuit card contains the audible tones, such as Dial Tone, Busy Tone, Ring
Back Tone, etc. The music on hold source, either the MUSIC ROM or the external source via FM lead, is
located on the PLO card. The tone and the music are inserted into their time slot at this circuit card.
Additionally, this circuit card provides the Voice Prompt function that inserts the designated time slot of
PCM (Speech Path...

1. General Function
The PU-SW00 circuit card provides the Time division Switch (TSW) and INT function for the IMX-U
system. Each circuit card provides switching for a Local Node (LN) and four PU-SW00 cards and two PU-
SW01 (HSW) cards achieve a maximum of 32,768 time slot (TS) switching for four (4) LNs. This circuit
card is located in ISWM of the ISW.
