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.

	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.
