The Cisco SPA-8XCHT1/E1 is an 8-port channelized T1/E1 Serial Shared Port Adapter (SPA). Let’s dive into the details:

Purpose and Features:

The SPA-8XCHT1/E1 is designed to provide a full 8-port channelized solution for various Cisco routers, including the Cisco 6500 Series, 7600 Series, ASR1000 Series, ASR9000 Series, and 12000 Series Routers.

• • It combines the benefits of shared port adapters (SPAs) and SPA interface processors (SIPs) using the Cisco I-Flex approach.
  • The extensible design prioritizes data, voice, and video services.
  • It offers improved slot economies by allowing modular port adapters that are interchangeable across Cisco routing platforms.
  • The I-Flex design enhances connectivity options and provides programmable interface processors for line-rate performance.
  • It supports various encapsulations, including MLPPP (Multilink Point-to-Point Protocol) and multilink Frame Relay (MLFR).

Technical Specifications:

• • Ports: Eight software-configurable T1 or E1 ports.
  • Channelization: The interfaces can be channelized, fractional, or unframed (E1) with up to 256 independent High-Level Data Link Control (HDLC) channels definable for T1 and E1 applications.
  • Integrated CSUs and DSUs: Eliminates the need for separate interface types for different connection requirements.
  • MLPPP Support: Hardware support for link aggregation greater than T1 capacity.
  • Hot-Swappable: The SPA is hot-swappable and supports service-transparent online insertion and removal (OIR).

Cost-Effectiveness:

• • The cost per T1 or E1 port is less than that of a standard serial port with external channel service unit (CSU) or data service unit (DSU).
  • This makes the Cisco SPA-8XCHT1/E1 a cost-effective solution for all WAN connectivity needs.
