Wideband Channel Resiliency; Edge Qam Redundancy; Where To Find Information On Solution Hardware Components - Cisco WCM300 - Channel Bonded Cable Modem Implementation Manual

Chapter 2 Cisco Cable Wideband Components
The show controllers modular-cable command shows the current state of the Wideband SPA's Gigabit
Ethernet ports. With the Cisco IOS CLI, the Wideband SPA's Gigabit Ethernet ports are not specified on
