Module Function Description
Passive
lobe access
RR-TL-4/S Passive Access Module for 4 lobes over
STP (2 slot width)
The TL-4 is a plug-in module for interconnecting
workstations to the Token Ring network. Transmission
distances for passive modules are:
RR-TL-4/U Passive Access Module for 4 lobes over
UTP
RR-TL/SD Passive Access Module for 4 lobes over
STP (1 slot width)
RR-TL/SU Passive Access Module for 4 lobes over
Screened Twisted Pair
Active lobe
Access
RR-TL-2/EDU Active Access Module for Extended
Distance connection of 2 lobes over UTP
The TL-2 is a plug-in module for interconnecting
workstations to the Token Ring network. The two-
port station access module provides regeneration of
the signal at each lobe, enabling guaranteed lobe
distances. Transmission distances are:
RR-TL-2/EDS Active Access Module for Extended
Distance connection of 2 lobes over STP
RR-TL-2/EDSU Active Access Module for Extended
Distance connection of 2 lobes over
Screened Twisted Pair
RR-TL-2/F Active Access Module for Extended
distance connection of 2 lobes over fiber
optic cable
RR-TL-4/AS Active Access Module for Extended
Distance connection of 4 lobes over STP
The TL-4 is a plug-in module for interconnecting
workstations to the Token Ring network. The four-
port station access module provides regeneration of
the signal at each lobe, enabling guaranteed lobe
distances. Transmission distances for active modules
are:
RR-TL-4/AU Active Access Module for Extended
Distance connection of 4 lobes over UTP
RR-TL-4/ASU Active Access Module for Extended
Distance connection of 4 lobes over
Screened Twisted Pair
RR-TL-4/ASD High Density Active Access Module for
Extended Distance connection of 4 lobes
over Screened Twisted Pair
RR-TL-4/CX Active Access Module for 4 lobes over a
single CoaXial cable
RR-SAT Active Sattelite Access Module for
connection to two smart LAU, over UTP
or STP.
The RR-SAT is a plug-in module for interconnecting
up to 8 workstations to the Token Ring network. It
meets all applicable IBM Token Ring and IEEE 802.5
requirements, and supports both 4 and 16 Mbps
networks.
RR-FTB The FTB is an FDDI to Token Ring
translation bridge for connection of a
Token Ring departmental LAN to an
FDDI backbone
The FTB is a plug-in module for connecting servers
directly to the FDDI backbone. Up to 256
workstaitons can be connected on the Token Ring
port side.
Note
UTP distances refer to category IV or V UTP cables such as AT&T 1061 and
2061. Distances will vary when a lower level cable (such as IBM type 3) is used.
