AS/400e server 830
166 AS/400e System Handbook
• 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 dialup or Shorthold Mode WAN.
The fundamental bus architecture of the AS/400 system is unchanged when using PCI
adapters. The AS/400 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-AS/400 system structures.

Interactive Features
The Model 830 supports various levels of interactive performance through the installation of
interactive features.
Interactive CPW is an approximate value reflecting the portion of Processor CPW that can be
used for workloads performing interactive-based tasks (5250).
• Any system administration job submitted to batch is not considered interactive work.
• Any use of Operations Navigator (GUI administration functions) is not considered
interactive work.
For a discussion of how these features influence system performance, see “IBM Workload
Estimator for AS/400” on page 28.
