Cisco ASR 9000 Adapter SPA-1XCHSTM1/OC3 1-port Channelized STM-1/OC-3c to DS0 Shared Port Adapter

Overview

The Cisco SPA-1XCHSTM1/OC3 is a Shared Port Adapter (SPA) developed for the ASR 9000 Series routers. This SPA delivers a customizable interface solution that enables a mix of channelized and un-channelized T1/E1 interfaces for clear channel applications and provides a single-port, channelized STM-1/OC-3c to DS0. The STM-1/OC-3c denotes Synchronous Transport Module level 1 or Optical Carrier level 3 in the SONET/SDH network hierarchy, implying its standard-compliant, high-speed data transmission capability. DS0 represents an introductory digital signaling rate, signifying its use in efficiently handling multiple digital signals within a single line. This modular SPA allows for network growth by simply adding more channelized interfaces, promoting scalability. It is also hot-swappable, so capacity expansion can be performed without causing system interruptions. It's an adapter that provides tremendous flexibility and scalability, making it integral to networks aiming for continuous growth.
