NxIQ MODULE
Nx FRAME RELAY MONITORING FOR TSU MULTIPLEXERS
|
ADTRAN's industry-leading and award-winning DSU/CSU family continues to
provide more flexibility with the NxIQ Module. The NxIQ Module installed in a
TSU multiplexer provides the visibility and control you need for both the
physical and logical connections made in Frame Relay networks. This intelligent
solution for managed Frame Relay access allows you to enjoy the monetary savings
of Frame Relay without giving up management visibility and control.
Real-time measurements of Frame Relay metrics are stored in the NxIQ module.
These metrics include statistics on throughput and utilization per port and PVC,
availability, utilization by protocol, top talkers, lost frames and PVC state,
excess bursting above CIR, network congestion (FECN, BECN, and DE), and
end-to-end delay on any or all PVCs. This data is crucial for pinpointing
specific traffic demands and problem sources in the network, for analyzing
traffic patterns, and for general maintenance and troubleshooting of the Frame
Relay circuit.
The statistics are stored in the NxIQ Module in a standard ASN.1 format
making the statistics available to any SNMP management platform or trend
analysis package. ADTRAN offers IQ View, a powerful Windows-based network
management system. IQ View combines the features of a complete SNMP management
platform and network trend analysis tool in one easy-to-use, low-cost package.
The NxIQ module supports multiple ways to access the collected performance
data. This management flexibility accommodates both the service provider and the
end user in any type of network configuration. Options include simple VT 100
connection, front panel, management access through inband dedicated or shared
PVCs, SLIPP/PPP or Ethernet (when installed in an "e" series TSU
multiplexer), and combination management. Combination management allows for
simultaneous and independent management by the service provider and the end
user.
The IQ family provides automatic dial backup upon interruption of Frame Relay
services. The NxIQ monitors both the physical link and the Frame Relay signal to
determine if an interruption has occurred. Once detected, the unit automatically
initiates a dial-up call around the Frame Relay network. A host IQ unit
initiates and accepts calls to and from IQ units at remote sites. Once
connected, the host unit merges backup traffic with the primary traffic still
being received from unaffected remote sites. The router or Frame Relay device
connected to the NxIQ module still receives all data as Frame Relay traffic over
the primary connection, allowing a virtually transparent transition. Once the
failed condition has been cleared and the Frame Relay interruption is over, the
IQ unit automatically restores traffic to the primary link.
Additional features such as an easy-to-use front panel interface and dial
backup combined with the quality, service and support that ADTRAN is known for,
makes the IQ Probe the obvious choice for Frame Relay monitoring. The IQ series
also includes the IQ Probe, DSU IQ, TSU IQ, and the TSU IQ+.
