iSeries IBM 9406, #4750 PCI ISDN BRI U IOA
(#4750 / #4751) PCI ISDN BRI IOAs
(Only available as REFURBISHED as of November 20, 2001)
#4750/#4751 are 4-port (8-channel) ISDN BRI (basic rate interface) PCI features. Using DSP technology, each BRI channel contains a fully integrated modem that supports both V.90 server and client functions. There are two options for connecting with #4750 or #4751: A remote analog modem may make a connection through the telephone network to a #4750/#4751 B-channel. Or, a remote ISDN device may make a digital ISDN connection to a #4750/#4751 B-channel. Each port consists of a 2B+D configuration. #4750, PCI ISDN BRI U IOA, is the U-bus (2-wire) version IOA used primarily within North America. #4751, PCI ISDN BRI S/T IOA, is the S/T-bus (4-wire) version IOA used primarily outside of North America. A wrap cable/plug and four 30-ft RJ-45 to RJ-45 network cables are shipped with the adapter.
The following protocols may run simultaneously on all eight B-channels and in any combination per port:
PPP -- may connect to remote ISDN devices or to remote synchronous or asynchronous analog modems.
IDLC -- may connect to remote ISDN devices over a digital connection.
G3 Fax Protocol -- may connect to remote analog fax devices or ISDN devices that support G3 FAX. G3 FAX works with Facsimile Support/400 and AS/400 Fax for Domino. The ISDN BRI IOAs support:
2-dimensional G3 images for minimum connect time
ECM Mode for guaranteed image integrity
AFP data streams with bar codes, overlays, signatures,
Fax Banner with date and time stamps on a page basis
DTMF tone detection for inbound Fax routing
(#4761) PCI Integrated Analog Modem
(Only available as REFURBISHED as of July 2, 2002)
Based on the latest DSP technology, #4761 allows the modem function to be integrated into the IOA and supports multiple analog modem ports (8-phone lines). Each port supports V.90 client functions as well as other modem standards such as V.34. #4761 will run the following protocols without an external modem:
PPP
SDLC
Fax
A wrap cable/plug and eight 30-ft phone cables are shipped with each #4761. An ASYNC line description is required for Fax, and can only be used for Fax.
Supported on the following systems: 270, 820, 830, 840, SB2, SB3
