Amherst College maintains a Siemens PBX telephone system that provides unrestricted access from most academic and administrative offices, and restricted access from most building entrance phones, dormitory hallway phones and outdoor emergency phones.
Telephone types in use include Siemens digital models, various wired analog models, and 900MHz and 5.8GHz cordless models. 2.4GHz cordless telephones are not permitted, because they interfere with collegiate use of wireless data networks on campus.
