17 Differences Between the Samsung KS16112/4 and Rockwell R96DFX/R144EFX
The KS16112/4 are pin - to- pin and software compatible modem devices that can be used to replace
the Rockwell R96DFX /R144EFX modem. Functionally, the Samsung and Rockwell modems are nearly
identical. However, there are a few differences between the two that the user should be aware of.
The KS16112/4 feature an improved equalizer with 48 taps thus allowing better performance without a
compromise equalizer. The KS16112/4 work over 7 Japanese links as well as over all EIA lines.
The equalizer is always T/2 fractionally spaced and there is no provision for a T-spaced equalizer.
Also when reading the equalizer taps from the DSP it should be noted that the direction of the time axis
is different from Rockwell
s
( i.e the smallest address corresponds to the oldest data ). The tap coefficients
between the Samsung KS16112/4 and Rockwell R96DFX / R144EFX are not interchangeable ( i.e taps
stored from the R96DFX / R144EFX cannot be loaded into the KS16112/4 ).
Instantaneous energy detector ( IED ) does not include state 2.
During DTMF detection the DEDT bit is the same as the DTDT bit.
The following DTMF parameters are not available:
Minimum cycle time
Minimum dropout time ( is always set to 5 ms )
Frequency deviation, low group
Frequency deviation, high group
Maximum energy hit time
Programmable Interrupt does not include dual port interface memory locations 0 and 10.
