ATM/WAN Testing Made Easy
Key ATM Features
and Functionality
To install or troubleshoot an ATM or WAN link, it is necessary to test for many
things: physical errors, equipment interoperability, ATM cell congestion, and
even LAN traffic problems. The Agilent Advisor offers integrated ATM, WAN,
and LAN protocol analysis capabilities, along with bit error ratio testing
(BERT), stimulus/response measurements, and statistical analysis capability -
everything required to get a good look at the physical layer, ATM/MAC layer,
and all of the upper protocol layers.
In addition, the Agilent Advisor can test ATM quality of service (QoS) with
contract conformant traffic and can check live traffic for conformance to a
traffic contract (policing). For Frame Relay, the Agilent Advisor can verify that
Service Level Agreements are met.
No matter what the traffic level, the Agilent Advisor will capture every cell or
frame on full-duplex network connections. It monitors non-intrusively and
decodes ATM or WAN data at full line rate. Further, it can simulate traffic from
either direction within a connection. In addition, it can process previously
captured data from its capture buffers or from a file for retransmission. The
analyzer not only captures traffic when the network is working - it provides
information when the network is broken - when it is needed the most.
The Agilent Advisor provides the following powerful ATM features and
functions:
Handles ATM testing rates from 1.5 Mb/s to 622 Mb/s; ATM Interfaces including
T1/E1, J2, E3/T3, STM-1/OC-3, STM-1e/EC-3, STM-4/OC-12, ATM25
(25.6 Mb/s UTP-3/5) and UTP155 are available as plug-in modules or undercradles
Auto-discovers up to 1024 Virtual Channels on all ATM interfaces except J2
(up to 4096 on the STM-4/OC-12 interface) and gathers statistics on each
Analyses protocols including full rate capture with capture and display filtering
and searching (e.g. set the capture filter to capture only ATM streams carrying
IP traffic with specific IP addresses)
Monitors, captures data, and decodes upper and lower layer protocols in real
time
Decodes and logs statistics for LAN encapsulated protocols over ATM,
including Voice over IP decodes: H.323 series, IETF series (SIP, MGCP, SGCP,
MEGACO), ITU-T T.38
Finds Errors in capture file or buffer
Decodes AAL-1, AAL-2, AAL-3/4, AAL-5
AAL-1 5 CRC statistics

Decodes IMA Control Protocol (ICP) cells
Real-time and post-processing User Assisted LAN over ATM
Emulates ATM UNI signaling check call set-up procedures
Emulates ELAN Join (LANE)
Generates user-defined cell traffic from a cell table
Retransmits captured traffic which has been copied and pasted to the cell table,
modified (e.g. VPI-VCI and/or embedded IP addresses changed); the HEC and
AAL-5 CRC-32 are automatically recalculated
Generates ATM ICMP Echo (PING)
Generates and analyses OAM cells
Tests ATM QoS performance to the ITU-T O.191 standard measures cell loss,
cell delay, cell delay variation, cell misinsertion and cell errors
Generates ATM traffic shaped to traffic contracts
Polices ATM traffic to traffic contracts
Tests simultaneously on two different or similar ATM interfaces
Tests simultaneously with other technologies (e.g. Frame Relay, Ethernet)
Tests physical frame layer and cell layer bit error ratios (BER)
Measures optical power
Pulse amplitude measurement on T1, E1, E3, T3 and STM-1e/EC-3 ATM interfaces
