It is allowed both in the Base System Unit and the System Expansion Unit. There is a
maximum of one #2750 per IOP. This feature requires country certification or homologation.
#2751 PCI ISDN BRI S/T IOA
The #2751 is a 4-port (8-channel) ISDN BRI (basic rate interface) full-size PCI card. Based
on the latest DSP technology, the #2751 allows connections to fax or data modems
connected to the telephone network with analog phone lines, as well as to other ISDN
devices. Each port consists of 2B+D configuration. The #2751 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.
A wrap cable and plug and four 30-foot RJ-45 to RJ-45 network cables are shipped with each
card.
The #2751 IOA supports full duplex mode. It supports the PPP, IDLC, and Fax protocols. It is
allowed both in the Base System Unit and the System Expansion Unit. A maximum of one
#2751 is allowed per IOP. This feature requires country certification or homologation.
#2761 Integrated Analog Modem
Based on the latest DSP technology, #2761 allows the modem function to be integrated into
the IOA and supports multiple analog modem ports (8-phone lines). Each line supports V.90
and lesser modulations. The #2761 IOA supports full duplex mode.
A wrap cable/plug and eight 30-foot UTP phone cables are shipped with each card.
This feature supports the SLIP, PPP, SDLC, and Fax protocols. An asynchronous line
description is required that can only be used for fax. The #2761 is configured as a single IOA
with eight individual resources available.
There is a maximum of one #2761 per IOP. The #2761 requires country certification or
homologation.
#9720 Base PCI WAN/Twinaxial IOA
The #9720 feature can be included as the base MFIOP to support ECS on the
communications adapter. The cable required for ECS is the #0348 V.24/EIA232 20ft/6m PCI
cable. The #9720 also supports Twinaxial Workstation Controllers (see “Workstation
Controllers” on page 96). The #9720 is supported for migration only.
Note: The #2720 PCI WAN/Twinaxial IOA can be ordered manually to change the console
from Operations Console. The administrative sales records should be RPOed to show a
#9720 Base PCI WAN/Twinaxial IOA installed.
