Other Call Establishment Methods
In addition to the configuration and operation methods in this chapter, the modem
supports other methods to establish and manage telephone connections:
• V.25bis ACU (for synchronous or asynchronous applications)
• NetView LPDA-2 ACU (for synchronous applications)
• IBM AS 400 (for synchronous dialing)
• External Auto-Call Units such as the Bell 801C
These methods are described in the sections that follow.
V.25bis ACU for Sync or Async Applications
The modem supports an ITU-TS V.25bis ACU for initiating calls from an intelligent
terminal, in synchronous or asynchronous formats, which supports:
• Addressed mode, to perform call-related tasks, such as storing phone numbers
in memory, dialing calls from memory, connecting/disregarding incoming calls
• Manual and direct call establishment methods. Direct mode lets you use DTR
transitions from the DTE to establish calls. Manual mode lets you manually
initiate and answer calls with a telephone and then transfer the call to the
modem.
Where Do I Go from Here?
For more information on the V.25bis ACU, refer to Chapter 3, Automatic Calling
Interfaces, in the 326X Series Modem Reference Guide. Programmers and System
Developers should also refer to Chapter 3 for a programming guide describing
asynchronous and synchronous data formats using the ASCII/EBCDIC character
sets.
NetView LPDA-2 ACU for Sync Applications
The modem supports Link Problem Determination Aid (LPDA-2). LPDA-2 is the
communications protocol between IBM host software and transmission devices for
exchanging diagnostic and control information. LPDA-2 commands provide a means
for an attached terminal to command the modem to dial a telephone number and
report back if the call is successful or not successful.
Where Do I Go from Here?
For more information on using the LPDA-2 ACU, refer to Chapter 3, Automatic
Calling Interfaces, in the 326X Series Modem Reference Guide for configuration
information and for information on NetView’s LPDA-2 dialing commands.
