Connecting to the Analog Dial-Up Line
The Excalibur Multirate DAP has an 8-pin modular jack labeled DL for connecting to the
analog dial-up telephone line. The correct cable to use depends on the mode of operation
selected and the telephone tariff used:
• For Programmable operation, use Cable Part No. 5956-149G-10. This cable has
8-pin modular plugs at both ends.
• For Permissive operation, use Cable Part No. 5956-149A-10. This cable has 6-
pin modular plugs at both ends.
To connect to the dial-up line, plug one end of the cable into the DL connector and plug
the other end into the telephone company's data jack. For programmable operation,
request Data Jack USOC RJ45S (CA45A in Canada) from the telephone company. For
Permissive operation, request Data Jack USOC RJ11C (CA11A in Canada)
Figure 3-5 shows the required dial line cable connections. Table 3-4 lists the pin/signal
assignments for the DL connector. (The leftmost pin is designated pin 1.)
