The Spok MAXPage is a stand-alone desktop paging transmitter with the capacity to store up to 1000 pagers in its database. The paging system uses the POCSAG protocol (2-Tone Voice is optional), operates in the UHF frequency band and can send alphanumeric, numeric, and tone only messages. The unit has a durable injection molded housing for extended product life, and incorporates a powerful 4 Watt internal transmitter, meaning it can provide coverage for small to medium sized paging sites. The MAXPage capabilities can be enhanced with a wide range of optional features that include an external computer keyboard, a telephone paging interface, and an RS232 serial interface for TAP, Scope, and COMP paging control protocols.
