The Cisco® cBR-8 Converged Cable Access Router Supervisor 250G performs the data forwarding and routing processing functions of the carrier-class cBR-8 Converged Cable Access Router.
The complete supervisor consists of two Field-Replaceable Units (FRUs): supervisor and supervisor Physical Interface Card (PIC). The supervisor PIC has all the physical interface ports and related PHY components onboard.
The Supervisor 250G offers:
● Flexible data path interconnection between active and standby supervisors to support active-active backhaul connectivity across all 4x100G ports from two supervisors in a cBR-8 system
● 1+1 redundant supervisor support
● Two integrated 100G Network-Side Interface (NSI) backhaul interfaces and one RJ45 GE management port support for IEEE-1588 PTP
● Field-replaceable and hot-swappable capabilities for minimal service disruption
● Industry-leading Cisco IOS® Software features and services
