Chapter 2

Cisco Cable Wideband Components

Base CMTS Components

The Cisco uBR-MC5X20S/U/H and uBR10-MC5X20U-D line cards use space-saving dense connectors.

Each line card supports online insertion and removal (OIR) and can be added or removed without

powering off the chassis. For more information on these cable interface line cards, refer to the document

Cisco uBR10-MC5X20S/U/H Cable Interface Line Card

(hardware installation).

Cisco Half-Height Gigabit Ethernet Line Card

The Cisco half-height Gigabit Ethernet (HHGE) line card is a single-port Gigabit Ethernet (GE) line card

that provides a trunk uplink to devices such as backbone routers, as well as connections to content

servers and IP telephony gateways. The GE line card provides the Cisco uBR10012 router with an IEEE

802.3z compliant Ethernet interface that can run up to 1 Gbps in full duplex mode.

Figure 2-4

shows the

faceplate for the HHGE line card.

Figure 2-4

Half-Height Gigabit Ethernet Line Card Faceplate

The Cisco uBR10012 router supports up to four HHGE line cards to allow connectivity to multiple

destinations, and to provide network layer redundancy. The HHGE line card requires a slot splitter card

that should be installed in either slot 4/0 or slot 3/0 on the uBR10012 router. Each slot splitter can hold

two HHGE line cards. Therefore, the uBR10012 base system with two slot splitters supports up to four

HHGE lines cards.

The HHGE line card uses a small form-factor pluggable (SFP) gigabit interface converter (GBIC)

module that supports a variety of Gigabit Ethernet interface types (SX LX/LH, and ZX), which you can

change or upgrade at any time.
