Since the basic PSTN (plain old telephone network) network link supports 64 Kbps bandwidth, I would say that is your answer.
In a Public Switched Telephone Network (PSTN), the primary types of media used for voice communication include copper twisted pair cables, which are the most common for residential phone lines, and fiber optic cables, which provide higher bandwidth and quality for long-distance communication. Additionally, coaxial cables are sometimes used in hybrid networks that combine telephony and internet services. Satellite links can also be part of PSTN infrastructure, particularly for remote areas. Each medium has its own characteristics in terms of bandwidth, distance, and signal quality.
By the way, call from VOIP can be received by pstn modem. But pstn cannot make a call to VoIP number.
PSTN stands for a public switched telephone network. A PSTN gateway is hardware components that third parties use to translate signaling.
ISDN is dial up lines and PSTN is a broadband line.

I think PSTN mainly serves to wired land-line(telephone) and MSC serves to cellular(mobile) network.
A PSTN may use a POTS line (dial-up connection), however, the PSTN may use other technologies as well. So, POTS refers to a way of connecting to an ISP or other service using a dial-up connection, whereas the PSTN refers to the phone company providing several kinds of data service connections.

PSTN will convert the digital signal from VoIP into voice signal. Their networks interacts using satellite frequency.
