Alarm Interface Controller Network Module
The Alarm Interface Controller (AIC) is a network module that greatly expands the network monitoring and control capabilities of the Cisco 2600 and 3600 Series routers. The AIC functions as an integrated entity residing within the Cisco 2600 Router to provide network alarm monitoring and remote control of network elements. The AIC reduces service provider and enterprise operating expenses by facilitating a single "box solution," doing away with the need for a dedicated external alarm monitoring device. This greatly simplifies network layout, monitoring, and control resulting in lower operations, administration, maintenance, and provisioning (OAM&P) costs. The AIC is supported in Cisco IOS® 12.2 (2) XG and 12.2(7)T. The AIC network module supports 64 discrete alarm inputs, of which 8 of the last 64 alarm points are software- configurable to accept either analog or discrete inputs. The AIC further supports 16 control relays to facilitate the remote control of network elements.
