Chapter 2 Cisco Cable Wideband Components Base CMTS Components The Cisco Gigabit Ethernet network uplink line card (part number UBR10-1GE) is also supported as a base CMTS component. It is a full-height line card that, for use with a Wideband SIP and SPA, should be installed in slot 3/0 or 4/0 of the uBR10012 router. However, the (full-height) Cisco Gigabit Ethernet line card is not recommended as a uBR10012 base system component for Wideband Cable because only two full-height Gigabit Ethernet line cards can be installed in the chassis. The uBR10012 chassis will support four Half-Height Gigabit Ethernet (HHGE) line cards in slots 3/0 and 4/0. Cable Interface Line Cards and Network Uplink Line Cards The cable interface line cards and network uplink line cards used on the Cisco uBR10012 base system are described in the following sections: • Cisco uBR-MC5X20S/U/H and uBR10-MC5X20U-D Cable Interface Line Cards, page 2-5 • Cisco Half-Height Gigabit Ethernet Line Card, page 2-7 Cisco uBR-MC5X20S/U/H and uBR10-MC5X20U-D Cable Interface Line Cards The Cisco uBR10-MC5X20S/U/H and uBR10-MC5X20U-D cable interface line cards transmit and receive RF signals between the subscriber and the headend over hybrid fiber/coax (HFC) network. Figure 2-3 shows the faceplate for these line cards.

Cisco Cable Wideband Components

Base CMTS Components

The Cisco Gigabit Ethernet network uplink line card (part number UBR10-1GE) is also supported as a

base CMTS component. It is a full-height line card that, for use with a Wideband SIP and SPA, should

be installed in slot 3/0 or 4/0 of the uBR10012 router. However, the (full-height) Cisco Gigabit Ethernet

line card is not recommended as a uBR10012 base system component for Wideband Cable because only

two full-height Gigabit Ethernet line cards can be installed in the chassis. The uBR10012 chassis will

support four Half-Height Gigabit Ethernet (HHGE) line cards in slots 3/0 and 4/0.

Cable Interface Line Cards and Network Uplink Line Cards

The cable interface line cards and network uplink line cards used on the Cisco uBR10012 base system

are described in the following sections:

•

Cisco uBR-MC5X20S/U/H and uBR10-MC5X20U-D Cable Interface Line Cards, page 2-5

•

Cisco Half-Height Gigabit Ethernet Line Card, page 2-7

Cisco uBR-MC5X20S/U/H and uBR10-MC5X20U-D Cable Interface Line Cards

The Cisco uBR10-MC5X20S/U/H and uBR10-MC5X20U-D cable interface line cards transmit and

receive RF signals between the subscriber and the headend over hybrid fiber/coax (HFC) network.

Figure 2-3

shows the faceplate for these line cards.

Faceplate

The Cisco uBR-MC5X20S/U/H and uBR10-MC5X20U-D cable interface line cards can be used for a

standard DOCSIS 1.X/2.0 service or for a Cisco Cable Wideband service or for a combination of the two.

These cable interface line cards support upstream and downstream traffic over DOCSIS-based cable

modem networks.

For a DOCSIS 1.X/2.0 and for Cisco Cable Wideband Solution, Release 1.0, operation, upstream data

from the subscriber comes through the upstream ports (US0-US19) on the line cards. The line card

processes and configures the data and sends it across the backplane to the WAN/backhaul card and out

to the Internet.
