The Cisco Clear Channel T3/E3 Shared Port Adapter, identified by part number SPA-4XT3/E3=, is an expansion module designed to offer high-performance connectivity solutions for service providers and enterprises. It has four ports which allow flexible and scalable access to T3 and E3 line rates. This adapter is well-suited for WAN (Wide Area Network) environments where network resilience and predictability are critical. The T3 (44.736 Mbps) and E3 (34.368 Mbps) capacities enable service providers and businesses to manage bandwidth-intensive data transmissions efficiently.
This module is part of Cisco Systems’ portfolio of expansion modules and leverages its sophisticated architecture to offer a clear channel feature, which means that it can handle the entire bandwidth of T3/E3 lines without additional configuration steps. By enabling the clear channel ability, the adapter ensures that no data framing is applied by default, making it possible for the link to carry data symmetrically and bidirectionally without protocol overhead. This ensures low latency and high throughput, suitable for voice, video, and large file transfers across a WAN.
The SPA-4XT3/E3= is designed to be compatible with Cisco modular routers and network gear. Its compact form makes it suitable for equipment that requires additional capacity without significant space or power requirements. Additionally, support for the Cisco IOS Software allows administrators to configure and manage this device effectively through a robust and familiar command-line interface (CLI).
With its ability to scale bandwidth on demand, the Cisco T3/E3 Shared Port Adapter is ideal for organisations requiring modularity, reliability, and performance in their wide-area networking infrastructure.
