iSeries Model 840
186 iSeries Handbook
• X.21 switched WAN dial-up or Shorthold Mode WAN
• Asynchronous communication speeds of less than 300 bps
• Data Rate Select signal on the EIA 232/V.24 interface. This function is used by some
older 2400 bps modems to reduce the speed to 1200 bps.
• LPDA-1 (Link Problem Determination Aids). This is a diagnostic function supported by
some (primarily older IBM) modems.
• V.54 local and remote loopback (diagnostics functions supported by some modems)
PCI adapters also do not support X.21 switched WAN dial-up or Shorthold Mode WAN.
The fundamental bus architecture of the iSeries is unchanged when using PCI adapters. The
AS/400e IOP continues to off load the main processor; isolate the host from adapter and
network errors; and manage, configure, and service the adapters. PCI architecture offers
advantages in flexibility over non-iSeries or non-AS/400e server structures.
