6.1.3 ATM Ports and Cabling
With its expansion, the IBM 8285 offers several physical kind of port connections
to handle twisted pair, fibers and coaxial lines. The physical specification of
each type of port are as follows:
• UTP/FTP/STP Ports
−
Physical Interface: RJ-45
−
25 Mbps Cabling Supported and Maximum Distances:
UTP Category 3 100 meters (unshielded twisted pair)
UTP Category 4 150 meters
UTP Cat.5 (100 Ohms) 160 meters
FTP (100/120 Ohms) 150 meters (foiled twisted pair)
SFTP (150 Ohms) 150 meters (shielded and foiled twisted pair)
STP (150 Ohms) 300 meters (shielded twisted pair)
−
155 Mbps Cabling supported and Maximum Distances:
UTP Cat.5 (100 Ohms) 100 meters
FTP (100/120 Ohms) 100 meters (foiled twisted pair)
SFTP (100/120 Ohms) 100 meters (shielded and foiled twisted pair)
STP (150 Ohms) 100 meters (shielded twisted pair)
The ports comply with the latest ATM Forum specifications concerning
pinouts. Although, the ATM25 cable uses the same number of pins as both
