Introduction to SIPs and SPAs Chapter 1 SIP and SPA Product Overview Shared Port Adapters The following list describes some of the general characteristics of a SPA: • A SPA is a modular type of port adapter that inserts into a subslot of a compatible SIP carrier card to provide network connectivity and increased interface port density. A SIP can hold one or more SPAs, depending on the SIP type. • Some SPAs provide services rather than network connectivity, and can be inserted into subslots of a compatible SIP. For example, the Cisco WebEx Node for ASR 1000 Series, which provides provides WebEx meeting services, and the DSP SPA which provides voice transcoding and transrating capabilities. • SPAs are available in the following sizes, as shown in Figure 1-1 and Figure 1-2: - Single-height SPA-Inserts into one SIP subslot. - Double-height SPA-Inserts into two single, vertically aligned SIP subslots.

SIP and SPA Product Overview
Introduction to SIPs and SPAs
Shared Port Adapters
The following list describes some of the general characteristics of a SPA:
A SPA is a modular type of port adapter that inserts into a subslot of a compatible SIP carrier card
to provide network connectivity and increased interface port density. A SIP can hold one or more
SPAs, depending on the SIP type.
Some SPAs provide services rather than network connectivity, and can be inserted into subslots of
a compatible SIP. For example, the Cisco WebEx Node for ASR 1000 Series, which provides
provides WebEx meeting services, and the DSP SPA which provides voice transcoding and
transrating capabilities.
SPAs are available in the following sizes, as shown in
Figure 1-1
and
Figure 1-2
:
Single-height SPA—Inserts into one SIP subslot.
Double-height SPA—Inserts into two single, vertically aligned SIP subslots.

Horizontal and Vertical Chassis Slot Orientation for SPAs
Caution
SIP subslot 0 is not available on the Cisco ASR 1002 Router as that is the slot occupied by the integrated
Route Processor with native Gigabit Ethernet ports.
Each SPA provides a certain number of connectors, or ports, that are the interfaces to one or more
networks. These interfaces can be individually configured using the Cisco IOS command-line
interface (CLI).
