TD Switch Block
The TD switch block consists of the time-division switch. It allows the replacement of
data of each channel on the PCM highway. By using the TD switch, the switch control of
B channel data can be facilitated on terminals with multi-functionality such as
extensions, three-way calls, and holding tone.
YTD439 supports 512 kHz to 2,048 kHz PCM highway and can perform switching on 8
channels. You can specify which output channels to connect the 8 channels of input
through the I/O register. One-to-one connection and one-to-multi-point connections are
supported.
The B channel data control block and the layer 1 control block (B channel data) are
connected to the PCM highway internally in the YTD439, and two channels are used by
each. The remaining four channels are connected to the PCM highway pins and allows
connection to arbitrary channels such as an external CODEC.
