IBM 8265: Product Description
The 12-port 25Mbps module (Feature Code 5012) is a single-slot module that uses
RJ-45 connectors, enabling the building of large ATM workgroups or a smooth
evolution from Legacy LAN to ATM networks.
The module has the following characteristics:
•
Twelve ports operating at up to 25Mbps to connect to stations, servers, hubs, or
switches. Each port may connect to:
– A concentrator with up to twelve workstation connections
– An ATM bridge with either up to four Token-Ring (N station) connections or up
to four Ethernet connections
– An ATM or multimedia workstation that requires a high bit rate
– A UNI, PNNI, or IISP device using a supported interface.
•
Physical interface: twisted pair cables with RJ-45 connectors
•
Workstation and server connections of up:
– 100 meters (329 ft.) on 100 ohm UTP Category 3 cable
– 255 meters (837 ft.) on 150 ohm STP cable.
•
A 1-port 155Mbps daughter card can be added as a feature. This card allows the
attachment of the module to a server or ATM backbone via a multimode fiber
cable. This port supports all types of interface: UNI, PNNI, and IISP, and allows
port-to-port connections of up to 2.2 kilometers (1.36 miles), depending on the
quality of the cabling used.
•
Up to four modules can be used in the 8265 (slots 1, 3, 5, and 7).
