Common dial-up services were Telex (Baudot, typically with Teletype

I suppose an operator had to type directly at the machine. Or, was there a method to type at some kind of offline machine, then take over something, like perforated tape?

Well if your machine had a punch you could prepare a tape off-line , and then send full speed when you had it ready and checked. In the UK Creed did produce "perforators", so a keyboard with a punch so I am sure Teletype did in the USA
