9.6 8260 Dual Fiber Repeater Module

This is a single slot module that supports 10 active lobe ports and two sets of fully repeated fiber RI/RO trunk ports. This is a per-port switching module, which means that any of the lobe ports or and trunk port sets can be assigned to any of the backplane segments. The main features of this module are:

∙10 lobe ports with shielded RJ-45 connectors.

∙Each lobe port has its own DPLL, which actively re-times and re-generates the signal on that port. This provides longer lobe distances on both UTP and STP. For information of the maximum lobe distances, please refer to

Table 26 on page 143.

∙Each lobe port can be connected to one of the 10 token-ring segments on the ShuntBus or one of the 11 isolated segments on the module.

∙2 sets of fully repeated fiber RI/RO trunk ports with ST connectors.

∙Each trunk port is fully repeated and supports multimode fiber connections for 62.5/125 fiber at distances up to 2 km.

∙Each set of trunk ports can be assigned to one of the 10 token-ring segments on the ShuntBus or one of the 11 isolated segments on the module.

Note: The lobe and trunk ports can be assigned to a maximum of 11 backplane or isolated segments. When you use a backplane (or isolated) segment the equivalent isolated (or backplane) segment is not available. For example if one or more ports are assigned to token_ring_1 segment, no port can be assigned to isolated_1 segment.

∙Simultaneous UTP and STP cabling is supported on the lobe ports attached to the same or different segments.

∙Support for beacon recovery on both lobe and trunk ports using the Recovery ASIC which is implemented on the module.

∙Support for address-to-port mapping using the recovery ASIC.

∙Support for fan-out devices and splitters for attaching up to 8 stations to each port. Note that the fan-out device or the splitter is required to provide a phantom signal; therefore, the 8228 cannot be used as a fan-out device with this module.

∙Support for connection of MAC-less stations (such as token-ring tracing tools) to all the lobe ports.

∙Automatic speed detection of the attached stations to the lobe ports, so that only the stations with the correct ring speed settings can attach to the network.

∙Simultaneous support of 4 and 16 Mbps token-ring networks on the lobe and trunk ports.

∙Compliant with the 802.5C (dual-ring recovery) on the trunk ports.

∙Support for installation of one T-MAC.

∙Support for installation of two Jitter Attenuator daughter cards.
