Electrical Safety

To avoid an electric shock or damage to the Cisco Unified Videoconferencing 3500 Gateway unit, servicing should be performed by qualified service personnel only.

To reduce the risk of damaging power surges, Cisco recommends installing an AC surge arrestor in the AC outlet from which the Cisco Unified Videoconferencing 3500 Gateway unit is powered.

Warning Do not attempt to open the Cisco Unified Videoconferencing 3500 Gateway unit.

Warning Changes or modifications to the device that are not approved by the party responsible for compliance could void the user’s authority to operate the equipment.

Grounding

The power cable of the Cisco Unified Videoconferencing 3500 Gateway unit should only be connected to a power outlet that has a protective earth contact. Do not use an extension cord that does not have a protective conductor (ground). The Cisco Unified Videoconferencing 3500 Gateway unit can become dangerous if you interrupt any of the protective conductors (grounding) or disconnect any of the protective earth terminals.

Caution For North American installations, select a 3-conductor (18 AWG) power supply cord that is UL listed and CSA certified. The cord must be terminated in a molded-on plug cap rated 125V/5A, with a minimum length of 1.5m (6 feet) and no longer than 4.5m (approximately 14 feet).

3527 PRI, 3522 BRI specifications

Cisco Systems has long been a leader in networking and telecommunications equipment, and its BRI (Basic Rate Interface) and PRI (Primary Rate Interface) products are essential components in enabling businesses to manage voice and data communications efficiently. Notable models such as the Cisco 3522 BRI and 3527 PRI have earned recognition for their robust performance and versatile features.

The Cisco 3522 BRI is designed to deliver high-quality voice and data services over ISDN (Integrated Services Digital Network) connections. With two B channels for voice or data transmission, each supporting up to 64 Kbps, this device is ideal for small to medium-sized businesses that require reliable communication solutions while maintaining cost-effectiveness. The Cisco 3522 BRI supports multiple protocols, making it a flexible choice to adapt to various network environments.

On the other hand, the Cisco 3527 PRI supports up to 30 B channels, thereby significantly increasing the capacity for voice calls and data transfer. This scalability makes the 3527 PRI suitable for larger organizations that demand higher throughput and call handling capability. It operates over T1 and E1 lines, allowing businesses to leverage existing infrastructure while improving operational efficiencies. Additionally, the 3527's advanced features, such as call processing and load balancing, contribute to a seamless communication experience.

Both devices support a range of technologies that enhance functionality and performance. They are equipped with Call Admission Control (CAC) to optimize bandwidth use and reduce congestion during peak traffic. Cisco's VoIP technology, including features such as voice provisioning, fax over IP, and QoS (Quality of Service) mechanisms, ensures voice clarity and reliability.

Security is paramount, and both the 3522 and 3527 incorporate various protocols such as SRTP (Secure Real-Time Transport Protocol) to protect voice communications against unauthorized access. Furthermore, integration with Cisco's unified communications offerings allows for a more cohesive communication strategy, ensuring that users can take advantage of collaboration tools and data services.

In conclusion, the Cisco 3522 BRI and 3527 PRI models stand out with their impressive feature sets and technologies, making them an excellent investment for businesses needing reliable, scalable, and secure voice and data communication solutions. Choosing Cisco means embracing a future-proof solution that can grow with your organization's communication needs.
