1. SYSTEM OVERVIEW
The IQ 710 is an all-encompassing performance monitoring device to address all seven layers of the net-
work. This intelligent solution for managed Frame Relay access allows you to enjoy the monetary savings
of Frame Relay and provides the visibility and control you need for both physical and logical connections
made in Frame Relay networks.
The IQ 710 provides two slots (one for Dial Backup and one for a Network Interface Module) and features
an Ethernet 10BaseT port for management applications. This product provides up to a full T1 worth of
access, and unlike other IQ models, the IQ 710 gathers information from all seven layers of the network.
The IQ 710 uses industry-leading technology to perform network monitoring and bundling network infor-
mation.
Layer 7 application monitoring in the IQ 710 includes the usage examination of FTP, Telnet, E-mail, data-
bases, corporate-wide ERP systems, Real-Audio, MPEG, general web traffic (including the specific URL
being visited), and many others. These Layer 7 metrics are used to evaluate overall network usage and effi-
ciency, as well as individual application response times or delays. In addition, these metrics are used to
analyze traffic patterns and for general maintenance and troubleshooting. The IQ 710’s Frame Relay met-
rics include statistics on throughput and utilization per port and per PVC, availability, utilization by proto-
col, top talkers, lost frames, PVC state, excess bursting above CIR, network congestion (FECN, BECN,
and DE), and end-to-end delay on up to 100 PVCs.
The IQ 710 is complemented by ADTRAN’s network management software suite, called N-Form. N-Form
is a modular, Java-enabled, Windows-based platform combining the features of a complete SNMP man-
agement platform with a network trend analysis tool. Using N-Form, the IQ 710 can be configured
remotely through a graphical interface. All alarm conditions and monitoring matrices may be viewed in
either graphical or tabular forms.
Traffic shaping is an optional software feature in the IQ 710 that lets the user allocate bandwidth by setting
the guaranteed bandwidth and maximum bandwidth. Traffic shaping can be applied on a PVC or applica-
tions level and is especially important in delay-sensitive applications such as packet voice.
