SPA-2XCHOC12/DS0 - Cisco ASR 9000 Series Shared Port Adapter Overview
SPA-2XCHOC12/DS0 - Cisco ASR 9000 Series Shared Port Adapter is a genuine edge and wide-area routing product from Cisco, a global name in networking whose platforms are used by enterprises, service providers and data-center operators alike. Belonging to the Cisco ASR 9000 Series family, the SPA-2XCHOC12/DS0 unit is built to the original factory specification, so it integrates with existing Cisco deployments predictably and behaves exactly as the platform documentation describes. In the network, it is deployed as a standalone unit or as part of a larger managed network, following the standard operating procedures of the platform.
From a specification standpoint, it offers 2 ports for client, server or uplink connectivity. These are the original factory figures for this model, giving administrators a clear picture of what the unit can deliver before it enters service. Standard mounting, cabling and management practices apply, so deployment follows the same procedures as other Cisco hardware already running in the environment.
Typical deployments include branch and campus WAN connectivity, service-provider edge and MPLS deployments, and secure remote-site interconnect. Organizations commonly source it for refresh programs, capacity expansion and spares management, keeping a tested unit on hand so outages stay short and replacements are predictable. The factory detail for this unit reads: “Cisco ASR 9000 Adapter SPA-2XCHOC12/DS02 Port Channelized OC12/DS0 Shared Port Adapter”. This makes it a practical choice when original-spec hardware is required at a predictable cost.

SPA-2XCHOC12/DS0 - Cisco Series Notes
This listing is part of the Cisco enterprise networking product family, sourced and tested by LinkNewNet for enterprise deployment. Cisco router is positioned at the WAN edge, branch, or service-provider aggregation point. It provides routing, VPN, QoS and security services, and integrates with Cisco IOS-XE / IOS-XR management.
Deployment guidance: When planning this SPA-2XCHOC12/DS0 unit into a network, confirm the software image (IOS/IOS-XE/NX-OS) required, the power and cooling profile, and the upstream/downstream interface types that match your existing infrastructure. For a like-for-like refresh, match the feature set of the units already in service so management and automation behave consistently.
Our Cisco reconditioning process: Every pre-owned Cisco unit at LinkNewNet passes a documented reconditioning flow before dispatch - visual inspection, internal cleaning, firmware verification, port-by-port testing, and configuration reset to factory defaults. This ensures the unit you receive operates reliably and integrates cleanly with your existing Cisco management tools.
Related models in this family: ASR-9001, ASR-9904, A9K-24X10GE-SE, ASR-9903, ASR-9901. Compare specifications to confirm the right port density, feature set and uplink options for your deployment.
