Overview
The CISCO C1861-UC-2BRI-K9 is a specialized networking device designed to meet the demands of small to medium-sized business communications. It integrates multiple services into a single unit, providing a streamlined solution for voice and data networking. This comprehensive overview focuses on its hardware specifications, delivering essential information for understanding its capabilities.
Central to its design are the two Basic Rate Interface (BRI) ports, which facilitate the device's connection to the Public Switched Telephone Network (PSTN), enabling efficient voice communication. Accompanying these ports, the device supports up to 8 users, making it suitable for small office environments. It also features Cisco Unified Communications Manager Express (CME) support, allowing for sophisticated voice services management.
For direct user connections, the device is equipped with 4 Foreign eXchange Station (FXS) ports. These ports are crucial for connecting analog devices such as telephones or fax machines, directly into the network. Internally, the device is powered by 256 MB of DRAM and a 128 MB flash memory, ensuring smooth operation and sufficient storage for firmware and configuration files.
The hardware's power requirements are versatile, with an AC input voltage range of 100 to 240 VAC and an AC input current of 4 to 2 A. Power dissipation varies significantly based on operational mode, consuming 80 W without IP phone support and up to 175 W when supporting IP phones.
Environmental conditions for operation are broad, with the device functioning optimally between 0 °C and 40 °C. It can operate in relative humidity ranging from 10% (non-condensing) to 85% (non-condensing) and at altitudes up to 6000 ft at 31 °C. Structurally, the device measures 2.625 inches in height, 10.5 inches in width, and 11.05 inches in depth, fitting into a 1.5 rack unit space. It weighs 8 lbs and operates with a noise level of 34 dBA at 25.6 °C, making it relatively quiet for office environments.
Safety and compliance are ensured through adherence to standards including CAN/CSA-C22.2 No. 60950-1, EN 60950-1, and UL 60950-1. For connectivity and configuration, the device includes one console port, facilitating direct device management, and six voicemail ports, expanding its voice messaging capabilities.
Key hardware features include:
- Two BRI ports for PSTN connectivity
- Four FXS ports for analog device connections
- 256 MB DRAM and 128 MB flash memory for efficient processing and storage
