— For an AT&T Paradyne model 3820 modem connected to the RS-232 ports (not in a modem pool),
enter the following for 9600 bps asynchronous operation. The same string should be used for the
modem at the called system:
at&f0 &d2 m0 \n1 \q3 s0=1 s2=128 s76=1 s78=1 s41=3 &w0
— A Telebit T1000 stand-alone modem may be connected to the RS-232 ports (not in a modem pool).
When the modem is first installed, power it up, open the front panel, and push the RESET button.
This puts the modem in conventional mode. You can then enter the following dial string for 9600
bps asynchronous operation. The same string should be used for the modem at the called system:
at &fm0 &d2 &c1 &k3 s0=1 s2=128 &w0 &y0
For T1000 modems only, the System 75, Generic 1, or Generic 3 analog stations form must have the
distinctive audible alert field set to n.
NOTE
Telebit modems can only make or receive calls from another Telebit modem (such as
another T1000). This modem is only certified to work on RS-232 ports 5 and 6.
• modem initialization status
This display-only field should be blank. If it is not blank, it is displaying the status of a previous
initialization and it will be updated when you save your data.
• DCP ports — data rate for incoming mode 2 calls or 0 if channel not
used
This field does not apply for systems with the TN366 or TN366B. For systems with the TN539 or
TN539B, this field indicates the data rate that the TN539 or TN539B will specify in response to a "data
options query" from the switch for an incoming DCP Mode 2 call (a call that uses modem pooling to
access this remote system). Permissible values are 0, 1200, 2400, 4800, 9600, and 19200. If the DCP
channels are not to be used, enter 0 in each field. For System 75, Generic 1, or Generic 3, enter 0 for
channel 2 and channel 4.
If the AUDIX system is using a 7400A or 7400B to talk with another AUDIX system that also uses a
7400A/B, the incoming DCP mode 2 data speed should match the speed set on the 7400A/B.
If the AUDIX system is receiving mode 2 calls from other AUDIX systems as well, and these systems
use speeds different from the 7400A/B, multiple speeds can be entered on the form. Contact the
BCSDC for information on using multiple speeds.
Saving Data
After you have completed this form, press CHANGE or RUN to save any changes or additions.
If initialization strings were entered, the AUDIX system will now send these strings to the modems to
initialize them. The modem initialization status fields show ‘‘pending’’. After a few seconds, press
ENTER to display the status of this new initialization attempt. If ‘‘pending’’ is still displayed, repeat the
wait-and-press ENTER procedure until some result is displayed. When a result is displayed, press SHIFT
and TAB at the same time to get to the modem initialization status fields. Then press f5 (field help) for
an explanation of the result.
