Modem and resource requirements

Learn about the modem and resource requirements needed for Point-to-Point TCP/IP Universal Connections.

The Electronic Service Agent™ and ECS service configurations created during activation are *PTP (Point-to-Point) TCP/IP Universal Connection based. If you do not have the modem or the resources to support these types of connections, the service configurations will not be usable or activation will fail due to lack of internal resources.

Modem requirements

Start of change Use Table 1 to determine the point-to-point functions that can be set up depending on your modem and resource. If you want to use this modem for problem-reporting and service-information transmission functions, ECS must also be configured to use TCP/IP, not SDLC or SNA communications. End of change

Modem in asynchronous mode

If the modem is configured to operate in asynchronous mode, both problem-reporting and service-information collection and transmission can be configured (Example modems are 2771 and 9771 internal modems, IBM^® 7855, IBM 7857, or IBM 7858 and dual model IBM 7852–400).

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 is optional) can be used for this function.

Typically, the default modem setting DSR (Data Set Ready) must be overridden. For an iSeries™ server to detect a hang-up, DSR must be set to follow CD (Carrier Detect). Refer to the modem manual for more information.

Communications I/O adapter requirements

AT&T dial-up and VPN connections are supported.

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 integrated modem on port 1 and a standard communications interface on port 2. To use port 2 of the 2771 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.90 integrated modem on port 1 and a standard communications interface on port 2. To use port 2 of the 2771 adapter, an external modem with the appropriate cable is required.
2805	Four port V.92 integrated modem WAN IOA
