Where did that bell that people ring at a bellhop's desk originate?

I have a few bits and pieces of the story:

A bellboy was originally a ship's bell-ringer, later a hotel page. The job's name is derived from the fact that the hotel's front desk would ring a bell to summon an available employee, who would "hop" (jump) to attention at the desk in order to receive instructions.

Bellhop is a 1910 shortening of bellhopper (1900), from the notion of hopping to action at the ring of the bell. Bell-boy was originally (1851) a ship's bell-ringer, later (1861) a hotel page.

Here are some really cool historical photos of bellboys and antiquated bells from hotel lobbies:
