Broadband Analyzer/Generator ANT-20/ANT-20E
S-12 Specifications “ATM Layer”
3 Signaling
The instrument simulates the signaling functions of a terminal on the user-network interface
(UNI). Up to 4 connections can be switched simultaneously.
“Channel associated signaling” can be selected as an option. Subaddresses can also be
optionally used.
3.1 Traffic Contracts
3.2 Signaling Analysis
Detection and display of the connection status of up to 4 connections simultaneously.
Measurement of the connection setup time (“Channel Setup Time”).
