2296A Modem Option Settings (Stand-Alone Modem Pool)
All 2296A modems now are shipped with a memory module. In earlier versions, a 140C1 Memory Module
V1.1 or V1.2 had to be installed in the right-hand slot at the bottom. New modems have a 140F2 module
which will work. The 2296A modem does not need the optional ACU board. If the data speed is slower
than 19.2 Kbps, the MNP board is also not needed.
Two groups of switches are located at the top of the 2296A modem faceplate. Set the switches according to
the following table:

For instructions on how to set the 2296A option settings from the front panel, see 2296A Option Settings
(D-Lead Modem Pool) earlier in this chapter. Below is a summary:
• Set Option 99 to 1 (allows options to be changed).
• Set all options to their default.
• Set Option 50 (async/sync) to y.
• Set Option 56 (Early DSR) to y.
• Set the speed to 9600 (same as the MTDM).
• Set Option 99 back to 2 (two).
To set the options from a terminal, use the follow initialization string:
at&f x1 v0 m0 e0 &c1 &d2 &s1 s0=2 &w RETURN
If successful, the response will be 0. A response of anything other than 0 indicates a fail.
