  • Class-Based Weighted Fair Queuing (CBWFQ): CBWFQ is supported by the CISCO2851-V/K9 to ensure that voice traffic is allocated the necessary bandwidth. With CBWFQ, the router can assign a higher priority to voice traffic and ensure that it is delivered with minimal delay and jitter.
  • Low Latency Queuing (LLQ): LLQ is supported by the CISCO2851-V/K9 to ensure that voice traffic is delivered with minimal delay and jitter. With LLQ, the router can assign a higher priority to voice traffic, and ensure that it is delivered with minimal delay and jitter.
  • Call Admission Control (CAC): CAC is supported by the CISCO2851-V/K9 to ensure that the network does not become overloaded with voice traffic. With CAC, the router can limit the number of voice calls that can be made at any given time, ensuring that the network is not overwhelmed with voice traffic.
  • Compression: The CISCO2851-V/K9 supports voice compression, which helps to conserve bandwidth and improve voice quality.

These QoS features help to ensure that the CISCO2851-V/K9 can handle the demands of voice traffic and deliver it with the necessary quality and reliability. It will ensure the smooth working of the voice system and the voice traffic is delivered with minimal delay and jitter.

Voice Compression and Conferencing

The Cisco 2851 Voice Bundle 11 Slots 2 Ports Router (CISCO2851-V/K9) is designed for large enterprise and service provider networks, which handle voice traffic over a wired network. The CISCO2851-V/K9 has several features for voice compression and conferencing to ensure that the voice traffic is delivered with optimal quality and efficiency.

  • Voice Compression: The CISCO2851-V/K9 supports voice compression, which helps to conserve bandwidth and improve voice quality. Voice compression reduces the size of the voice packets, allowing more packets to be sent over the network at a time, improving the efficiency of the network.
  • G.711, G.726, G.729, and G.722 codecs: CISCO2851-V/K9 supports various codecs such as G.711, G.726, G.729, and G.722, which are used to compress and decompress voice traffic. These codecs provide different levels of compression and audio quality.

About Refurbished Products

Refurbished products are typically refurbished by an Original Manufacturer or an affiliate of the manufacturer or 3rd party facility. This product may have minor blemishes due to normal product usage and doesn't necessarily come with documentation and software unless indicated, but has been well tested and generally has never had any defects.

Routers lead the line as the first line of network security in homes and offices. It prevents intrusion into a network while creating a firewall to provide the highest level of security on several network types. They are the best ways of keeping computer systems, network systems, and information contained in them safe from intrusion.

A router is designed to be more capable than several other network devices such as hubs or switches that can only carry out basic network functions. For instance, a hub only transfers data between network devices without analyzing or doing anything with those data. On the other hand, routers are able to analyze data sent between network devices. They can change the packaging of such data and send it over to a different network.

Routers are the perfect devices to share an internet connection between multiple computers in home networks. A router typically connects to the modem using a network cable. Router networking occurs via a WAN port or the internet. There are also wireless routers that connect to devices using different wireless standards.

Important Features

Multi-core Processor

The hardware inside these routers allows them to cope with several network use at the same time. Many of these routers come with dual-core and quad-core processors. These processor options allow them to handle lots of data more effectively. Users can use their Wi-Fi routers for activities such as video streaming, online gaming, data backups, and more. Even while carrying out those operations, the routers perform at the highest levels.

Multi-band options

Users will get routers that broadcast wireless signals over two frequencies (for dual-band) or more (for tri-band and others). These routers run at frequencies that can cover a wide expanse of area. They are not congested and are perfect for office buildings, homes, and large enterprises. Clients will find routers that emit their signals between 2.4 GHz and 5GHz.

Built-in Security Features

These router networking devices also come with security features such as device quarantine, firmware updates, automatic updates, and more. The features allow them to provide network-level protection against attacks. With these features, cybercriminals will be unable to infiltrate home networks.

Types of Routers

There are several types of routers that users can benefit from. Some of them include:

  • Core Routers. These are the types used by Internet Service Providers. They are the fastest and most powerful types. They sit at the center of the internet and forward data through the main fiber Optics.
  • Wireless Routers. These work in a similar manner as a home or business LAN. However, they give room for better mobility for laptops, tablets, and other portable devices. These types offer transmission over short distances.
  • Enterprise Routers. These are the types employed by large companies. Organizations use enterprise routers to connect their networks to these core routers.
  • Branch Routers. These types connect an enterprise's remote offices to its Wide Area Network (WAN). They come with improved features such as wireless LAN management, time-division multiplexing, WAN acceleration, and more.
  • Edge Routers. These are the most commonly used types in homes and small businesses. They are low-capacity devices that connect to the public internet or private WAN, or external LAN.
  • Logical Routers. They function similarly to hardware to create several network routes.
