    • What is a QSIG?

      What is a QSIG?

      QSIG is a signaling protocol that is  based on ISDN. It communicates signals between private branch exchanges (PBXs) within a Private Integrated Services Network (PISN) using the application-level ROSE and connection-level Q9.31 protocols. QSIG uses ISDN as the physical link layer in the exchanges and is often used in enterprise voice or integrated service networks.

    • MTU (Maximum Transmission Unit)

      MTU (Maximum Transmission Unit)

      The MTU (Maximum Transmission Unit) is the size of the largest datagram that can be sent over a network. If a datagram is larger than an MTU, the datagram must be fragmented into multiple smaller datagrams. Default MTU Sizes Most network technologies have default MTU sizes which may be changed by the network administrator. Network

    • DNS Cache

      DNS Cache

      DNS (Domain Name Server) is the web server used to resolve a website’s name to its Internet Protocol (IP) address. DNS servers across the Internet are either considered authoritative with regards to a website name and corresponding IP address or are required to verify the IP address with another DNS server that will in turn

    • How to Find DNS Servers

      How to Find DNS Servers

      The easiest way to find DNS servers is by using the ‘nslookup’ tool. Start nslookup Set the search type to NS. This tells nslookup to search for nameservers Finally, enter the domain name for the nameservers being searched for Here are some search examples for the most popular searches: Finding the Lincsat DNS Servers $

      Data Link Layer

      The Data Link Layer is layer two of the OSI model. It resides above the Physical Layer and below the Network Layer. The Data Link Layer is responsible for communications between adjacent network nodes. Hubs and switches operate at the Data Link Layer. The Data Link Layer is logically divided into two sub-layers: The Media

      How Do ADSL Microfilters Work?

      ADSL Internet Access Asynchronous Digital Subscriber Line (ADSL) is a broadband Internet option that is commonly available in many locations. Asynchronous only means that the download speeds and the upload speeds are different (with the upload speeds usually being significantly lower) and provides a fast option to browse the web. Internet access through ADSL requires one

      MAC Addresses (Media Access Control)

      A MAC address is an address that exists on Layer 2 of the OSI Model. Layer 2 of the OSI model is the Data Link Layer. The Data Link Layer consists of two sublayers, the Media Access Control (MAC) layer and the Logical Link Control (LLC) layer. The MAC sublayer controls how a network node
