Off-Premises Nonswitched Connection
Off-premises peripheral equipment must be equipped with an originating
modem (see Figure 2-48). The connection is made from the CO through the
TAE to a dedicated modem (optioned for autoanswer) connected to the
appropriate Call Processor port.

Off-Premises Switched Connection
To provide off-premises switched access, the peripheral equipment accesses
the system either as an off-premises (analog) station or simply as a dial-up
connection through the CO. In either case, the peripheral equipment must be
equipped with an originating modem.
The CPU/Memory port may be connected to a modem, as shown in Figure
2-48, and the telephone (2-wire) side of the modem connected like a station
to a ZTN78 Tip Ring Line CP port.
In this case, the peripheral equipment
user sets up a call (station-to-station in the OPS case, trunk-to-station in a
dial-up configuration) to the Call Processor port.
The CPU/Memory port may alternatively be connected and switched via a
TN726 Data Line CP port, as shown in Figure 2-47. In this case, the system
must be equipped with a TN758 Pooled Modem CP to support the analog to
digital connection.
