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.

When the uBR1012 router is used as a wideband CMTS, slots 1/0 and 2/0 are used for the Wideband
SIPs. 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
