transport layer define above. The options for this setting are:
Protocol Type
Within each Circuit Type there are certain specific protocols. The Protocol Type drop
down list includes the most common protocols used in the USA/Canada and Europe.
One of these pre-defined options for Protocol Type should work in approximately
97% of installations on the public telephone network. The protocols listed will
depend on the setting of the Circuit Type and the type of Telco Trunk Interface
installed in your 2101 Hub.
If RBS is selected as your Circuit Type then the following options are available
(applies to all Telco Trunk Interface versions):
The Protocol Types for RBS are listed below.
If PRI is selected for your Circuit Type then the options available will vary
depending on the 2101 Telco Trunk Interface installed.
T1 PRI Protocol Types (USA & CANADA)
For the PRI/T1 Interfaces (USA/Canada version, Telos Part #2091-00013 and
