I/O Adapter
255
I/O Adapter
Four 30-ft RJ-45 to RJ-45 network cables are shipped with each card.
The #4750 IOA supports full duplex mode. It supports the PPP, IDLC, and Fax protocols.
This feature requires country certification or homologation.
#4751 PCI ISDN BRI S/T IOA
The #4751 is a 4-port (8-channel) ISDN BRI (basic rate interface) full-size PCI card. Based
on the latest DSP technology, the #4751 allows connections to fax or data modems
connected to the telephone network with analog phone lines, as well as to other IDSN
devices. Each port consists of 2B+D configuration. The #4751 is the “S/T”-bus (4 wire)
version IOA.
• For data mode support, the B-channel supports digital data at 64 Kbps.
• For modem mode support, the B-channel supports V.90 and lesser modulations.
Four 30-foot RJ-45 to RJ-45 network cables are shipped with each card.
The #4751 IOA supports full duplex mode. It supports the PPP, IDLC, and Fax protocols.
This feature requires country certification or homologation.
#4761 Integrated Analog Modem
Based on the latest DSP technology, #4761 allows the modem function to be integrated into
the IOA and supports multiple analog modem ports (eight phone lines). Each line supports
V.90 and lesser modulations. The #4761 IOA supports full duplex mode.
Eight 30-foot UTP phone cables are shipped with each card.
This feature supports the PPP, SDLC, and Fax protocols. An asynchronous line description is
required, which can only be used for fax. The #4761 is configured as a single IOA with eight
individual resources available.
The feature requires and country certification or homologation.
#4801 PCI Crypto Coprocessor
The #4801 is a hardware cryptography solution based on the IBM 4758 card. The #4801 is a
half-length PCI card that offers rich cryptography function, secure storage of cryptographic
keys, and triple DES capability. The level of the cryptographic function is determined by the
Cryptographic Access Provider Licensed Program, which is used to set the key length in the
adapter.
The #4801 is available worldwide.
