Configuration Considerations

Setting AGC and CTS Delay

The ASM-10/8 receiver consists of the following components:

The receiver filter, which removes all the out-of-band frequencies.

The automatic equalizer, which comprises several equalizers activated according to baud rate.

The digital AGC, which automatically compensates for the attenuation of the line.

The following are general recommendations for the setup position of the AGC and CTS delay:

For point-to-point applications, set AGC to ON and CTS delay to 8 msec.

In multipoint or star applications, the AGC and CTS delay settings depend on the distances between the modems (see Table 2-2and Table 2-3).
