Note
The FE1 Daughtercard comes with this label which specifies that the E1
interface complies with the Australian requirements ACA TS 016 - 1997 for
connection to E1 SELV services. Also the E1 interface meets the IEC950
specifications for TNV1.
Channelized Data is not Supported for Ports 7, 10 or 13
Although the "Channelized" and "ISDN-PRI" data features are configurable under
the "Format Type" parameter for T1/E1 daughter cards on the Vanguard 6435/55
products, these features are not supported, and their use can result in unpredictable
behavior.
Do not configure "Format Type" to "Channelized” or “ISDN-PRI". Set the default
“Format Type” parameter to “Fractional”.
