Let's analyze the time required to send a file of $1,280,000$ bits from Host X to Host Y over a circuit$-$switched network. Suppose all network links use TDM with $32$ slots and have a bit rate of $3\mathrm{.}072$ Mbps$.$ Also, it takes $300$ milliseconds to establish an end$-$to$-$end circuit before Host X can transmit the file.

How long does it take to send the file?
