Is Occult considered Arcane Caster (can they use Arcane Wand?)

Hello, could someone helps with Occult rules:

At page 31, section "Channeling the Arcane" [1 Age book] listed 2 variants for source of channeling: Wizardy and Sorcery, but later in the Occult Section [page 33] described channeling for Occult. The phrase "Arcane caster(s)" used in "Channeling the Arcane" section, but does not in Occult section.

Arcane Wand [page 155, 1 Age book] : "Wands allow Arcane Casters to manipulate Arcane channeling die results ..."

Does it means that "Arcane caster(s)" means "Wizards and Sorcerers", and Occult casters cannot use Arcane Wand even they have channeling too? Or list in Channeling section is just a example, and every model that have Arcane Wand and uses channeling while cast power can use wand and manipulate channeling die?
