There is paging on the channel in a way. Saint Louis County does actually transmit a two-tone page, but I know of no pagers set to alert on it. Similar to the way they transmit two-tone on the Duluth Fire talkgroup, but still use DTMF over VHF for station alerting. The two-tones are just use to alert that a call is being broadcast.
Their main operations are on ARMER, with a permanent patch to VHF and an inter-system link to WISCOM. The VHF system is still fully operational and is used by some units when out of ARMER range or without access to an ARMER radio. Similarly some bordering services in Wisconsin use the channel to communicate with the ambulances or dispatch when needed.
