ADTRAN 1200255L1 NXIQ NETWORK MONITORING DEVICE

ADTRAN's 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.
