Overview
The Cisco uBR10012 router manages all protect switching control plane events and system upgrades.
Cisco IOS Release 12.2(33)SCG and later releases for Cisco uBR10012 router are required for operation with
the Cisco UBR-RFSW-ADV. When the Cisco uBR10012 router determines that a cable interface line card
failure has occurred, it enters into protect mode and additionally commands the Cisco UBR-RFSW-ADV to
enter protect mode.
The Cisco UBR-RFSW-ADV supports the following line cards on the Cisco uBR10012 router:
• Cisco UBR-MC20X20V
• Cisco uBR-MC3GX60V
The Cisco UBR-RFSW-ADV enhances overall system usability by providing easy cabling using the same
quick-connect UCH system used on all Cisco uBR10012 router cable interface line cards.
The Cisco UBR-RFSW-ADV provides the following enhancements over the earlier Cisco uBR 3x10 RF
Switch units:
• One Cisco UBR-RFSW-ADV replaces two uBR 3x10 RF Switch units.
• UCH type connectors allow easy cabling and improved RF and electromagnetic interference (EMI)
performance.
• Image upgrade is improved.
• RF path performance is improved with significantly less insertion loss.
• 54 to 1002 MHz downstream frequency range.
• 5 to 85 MHz upstream frequency range.
• Fully-redundant control ports.
