Chapter 2 Cisco Cable Wideband Components Wideband CMTS Components Table 2-3 Cisco uBR10012 Wideband Components: Minimum and Recommended Hardware Component Wideband SIP (SPA Interface Processor) Part Number: UBR10-2XDS-SIP Wideband SPA (Shared Port Adapter) Part Number: SPA-24XDS-SFP Minimum 1 Recommended 1 1 Varies* * The number of Wideband SPAs required will vary depending on the set of services and number of subscribers being supported. Cisco Wideband SIP A SPA interface processor (SIP) is a carrier card that inserts into a router slot like a line card. The Wideband SIP provides no network connectivity on its own. The Wideband SIP occupies two full height slots on the uBR10012 router. Each Wideband SIP supports two Wideband SPAs. Figure 2-6 shows the Wideband SIP with two Wideband SPAs installed.

Slots 3/0 and 4/0 are reserved for half-height Gigabit Ethernet line cards. Online insertion and removal (OIR) is supported for both the Wideband SIP and the individual Wideband SPAs. For more information on the Wideband SIP, see the Cisco uBR10012 Universal Broadband Router SIP and SPA Hardware Installation Guide and the Cisco uBR10012 Universal Broadband Router SIP and SPA Software Configuration Guide. Cisco Wideband SPA The Wideband SPA (Figure 2-7) is a single-wide, half-height shared port adapter (SPA) that provides Wideband Protocol for a DOCSIS Network formatting to the downstream data packets. The Wideband SPA is used for downstream data traffic only. It has one active and one redundant Gigabit Ethernet port that are used to send traffic to the external edge QAM device.
