4.2.4 Leased-Line Modem Communications Card
The Leased-Line Modem Communications Card is a 202T modem that is FCC part 68 tested for use
with leased-line or private-line telephone lines. Refer to Figure 4-4. Two or four-wire, half or full-
duplex asynchronous operation is supported at a software selectable 300, 600, and 1200 baud to Bell
and CCITT standards.
LED indicators on the card show the status of the RXD, TXD, DTR, DCD, CTS, and RTS
control lines. LED indicators are detailed in Table 4-1.
The leased-line card has three jumpers that permit either two-wire or four-wire operation. Refer to
Section 4.4.4 for information on setting these jumpers.
