Modem and resource requirements

The Electronic Service Agent™ (ESA) and Electronic Customer Support service configurations created during activation may be PTP (Point-to-Point) TCP/IP Universal Connection-based. The modem and resource requirements for a PTP configuration are listed below.

Modem requirements

The point-to-point functions that can be set up depend on your modem and resource. Refer to the table later in this topic to determine the functions. If you want to use this modem for problem-reporting and service information transmission functions, Electronic Customer Support must also be configured to use TCP/IP, not Synchronous Data Link Control (SDLC) or Systems Network Architecture (SNA) communications.

Modem in asynchronous mode

If the modem is configured to operate in asynchronous mode, you can configure both problem-reporting and service information collection and transmission (such as 2793 and 576C internal modems, dual mode IBM 7852–400, and MultiTech MT5600BA-V.92 external modems).

Note: If you use a non-IBM modem, any asynchronous modem that supports the RS-232 (EIA 232) serial interface and the V.34/V.42 protocol (V.90/V.92 is optional) can be used for this function.

Typically, the default modem setting data set ready (DSR) must be overridden. For a System i® platform that is to detect a hang-up disconnection (modem has hung up), DSR must be set to follow Carrier Detect (CD). Refer to the modem manual for more information.

Communications I/O adapter requirements

Determine if you have one of the following compatible I/O adapters.

Table 1. Adapters and descriptions
Adapter	Description
2699	Two-line WAN IOA. This IOA requires either a 2629 LAN/WAN/Workstation IOP or MFIOP.
2720	PCI WAN/Twinaxial IOA.
2721	PCI Two-line WAN IOA.
2742	Two-line communications IOA.
2745	PCI Two-line WAN IOA (replaces IOA 2721).
2771	Two-port WAN IOA, with a V.90/V.92 integrated modem on port 1 and a standard communications interface on port 2. To use port 2 of the 2793 adapter, an external modem with the appropriate cable is required.
2772	Two-port V.90 integrated modem WAN IOA.
2793	Two-port WAN IOA, with a V.92 integrated modem on port 1 and a standard communications interface on port 2. To use port 2 of the 2793 adapter, an external modem with the appropriate cable is required.
2805	Four-port V.92 integrated modem WAN IOA.
576C	Two-port WAN IOA, with a V.92 integrated modem on port 1 and a standard communications interface on port 2. To use port 2 of the 576C adapter, an external modem with the appropriate cable is required.

Note: IOA - input/output adapter; PCI - Peripheral Component Interconnect; WAN - wide area network.
