Simulation
Because the Agilent Advisor is a multitasking instrument, the user can perform
any of the active stimulus/response tests while the analyzer simultaneously
monitors the tests effect on the network.
The Agilent Advisor WAN provides a series of pre-written and pre-configured
test routines; the user can easily write others. Test scripts can be customized and
saved as a new test to build a library of powerful test sequences tailored to the
user’s individual applications.
LMI Emulation
Emulation is understood in the Frame Relay Industry as the testing capability
of a test device to replace either side of the network and provide the functions
of the replaced side. This implies the implementation of appropriate state
machines, which allow the tester to interact according to protocol standards.
The Agilent Advisor provides the following emulation capabilities according to
the Frame Relay Forum Implementation Agreements FRF.1.1 and FRF.2.1 and
ITU-T Q.933 Annex A.
• UNI-User (CPE) Emulation
• UNI-Network (Switch) Emulation
• NNI Emulation (bi-directional polling)
The UNI-User (CPE) emulation implies unidirectional polling from the User or
Customer Premise Equipment (CPE) to the Network (Switch).
The UNI-Network (Switch) emulation implies unidirectional replies from the
Network (Switch) to polling from the User or Customer Premises Equipment
(CPE).
The NNI emulation implies bi-directional polling from Network to Network.
(NNI).
The simulation application allows transmitting ICMP PING Requests to the
network as well as the ability for sending a capture buffer to the network.
