INSTALLATION
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.
1.Following the instructions for connecting off-premises stations, connect the OPS line from the RJ21X network interface through the TAE connecting block to the SIP.
2.Using a modular telephone mounting cord, connect a modem to the other side of the appropriate adapter.
3.Using an M7U-87 Cord, connect the RS-232C port on the modem to the RS-232C receptacle on a 355AF Adapter.
4.Locate the Z210A2 Adapter jack connected to the desired Call Processor port. Using a D8W-87 modular cord, connect the jack to the 355AF Adapter.
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.
