Overview
The Cisco SPA-8XCHT1/E1 is a Shared Port Adapter designed to provide high-density networking solutions. It features 8 ports, increasing the port density for businesses and network environments. Each port connects via an RJ-45 connector, with an option for an RJ-45 to BNC adapter cable, facilitating flexible installation and deployment across various physical interfaces.
This device supports multiple encapsulation protocols, enhancing its versatility in network function and design. It includes High-Level Data Link Control (HDLC) for reliable data transfer, Point-to-Point Protocol (PPP, RFC 1662) for direct connection between two nodes, and Frame Relay (RFC 1490) for efficient data transmission in packet-switched networks. These protocols ensure compatibility and efficient operation within diverse networking environments.
For T1 connections, the SPA-8XCHT1/E1 offers a data rate up to 1.536 Mbps per port, suitable for high-speed data and voice applications. It supports both D4 Super Frame (SF) and Extended Super Frame (ESF) framing, as well as AMI or B8ZS line encoding, providing flexibility in configuring data transmission methods. The device also adheres to ANSI T1.403 and AT&T TR 54016 standards for Facility Data Link (FDL), ensuring reliable communication and compatibility with existing network infrastructure. Users can select T1 cable length in increments from 0 to 655 feet and adjust CSU line build-out (LBO) and receiver gain for optimized signal quality.
E1 connections benefit from a data rate up to 2.048 Mbps (unframed mode) or 1.984 Mbps (framed mode) per port. The SPA-8XCHT1/E1 supports both 120-ohm impedance directly and offers a 75-ohm configuration option through the RJ-45 to BNC adapter cable, accommodating various E1 installations. It allows for unframed E1, CRC4, or non-CRC4 framing and utilizes HDB3 line encoding, ensuring efficient and flexible data transmission options for E1 networks.
- Reliability is enhanced with Online Insertion and Removal (OIR) and a single SPA software reset feature, facilitating maintenance without significant downtime.
- It is managed through Simple Network Management Protocol (SNMP), allowing for easy integration and management within existing network management frameworks.
- The device complies with RFC 1406 MIB standards, ensuring comprehensive monitoring and management capabilities.
