Telesyn Service Guide (Special Network Configurations)
7. Special Network Configurations
7.1 Overview
When configuring the overall network that is going to support the voice, video, and data services, certain topolo-
gies (such as RSTP and EPSR) are used to provide a level of protection so that services are not affected in case of
an outage of a network component, or that there is a minimum of service interruption. These topologies as they
relate to the Telesyn features are explained in the Telesyn User Guide. Moreover, in the feature table in each Sec-
tion of this document, a table lists for each service the kinds of topologies that can be used.
There are, however, some special configurations that allow the customer to provide a more efficient (or cost-
effective) way to offer the services using special or existing facilities. This leverages the customer’s ability to
make these services available using the Telesyn components.
7.2 FE10 Upstream Interface
7.2.1 Overview
The Telesyn User Guide explains the configuration that was available in release 5.0, and that in release 6.0 many
restrctions were removed so that voice, data, and video services are all supported with an FE/FX interface with an
upstream network interface. Moreover, IGMP snooping is available on an FE/FX port that is configured as a net-
work interface.
7.2.2 Feature Interaction
Table 7-1 lists the features that are availalble for the FE/FX10 upstream interface.

can be designated as having upstream forwarding mode. The user can
therefore add FE ports to UFO VLANs.
