Testing Switched Virtual Circuits (SVCs)

VI: ATM Test Control and ATM Test Results
2.1 General features of the signaling (Software version 6.5)
The signaling functions of a terminal on the user-network interface (UNI) are emulated. The
implementation used has the following features:
• Support for "Calling", "Called" and "Self Call" modes.
• The signaling channel is freely selectable. The default setting is VPI=0, VCI=5.
• "Associated" and "Non-associated" signaling can be selected (for Q.2931 only).
• The following standards are supported:
– IITU-T Q.2931
– ITU-T Q.2961
– ATM Forum UNI 3.0
– ATM Forum UNI 3.1
• The following signaling AAL standards are supported:
– ITU-T Q.2110
– ITU-T Q.2130
– ITU-T Q.SAAL.1
– ITU-T Q.SAAL.2
• The following address formats are supported:
– Native E.164
– NSAP ICD
– NSAP DCC
– NSAP E.164
– NSAP E.191
• Sub-addresses are supported
2.2

Interoperability with other instruments

The ANT-20 completely fulfills the quoted standards. If you make a connection to any other
instrument, please note the following:
• The setup message that is generated contains the following information elements (IE):
– Protocol discriminator
– Call reference
– Message type
– AAL parameter: User defined AAL (only if the "User defined AAL type" option is selected;
– ATM user cell rate
– Broadband bearer capability: BCOB-X
– Called party number
– Called party subaddress (only if subaddresses are used)
– Calling party number
– Calling party subaddress (only if subaddresses are used)
– QoS parameters
Technical Background
otherwise this IE is omitted.)
