You can make the following types of data calls through an analog-to-digital

inside calls to digital data stations including
calls to a local host computer
calls to a workstation on a local area network (LAN)
outside calls to digital data stations using a Primary Rate Interface (PRI)
digital line/trunk or pool (Hybrid/PBX only)
Calls through a modem pool are placed using two-stage dialing. In the first
stage you dial the extension for the data hunt group for the analog-to-digital
modem pool, and in the second stage you dial the extension or telephone
number of the digital data station you are calling. The second stage of the call
is automatically private.
