In computer networking, the maximum transmission unit (MTU) is the size of the largest protocol data unit (PDU) that can be communicated in a single network layer transaction. [1]: 25 The MTU relates to, but is not identical to the maximum frame size that can be transported on the data link layer, e.g., Ethernet frame.
Using DMT is useful since it allows the communications equipment (user modem/router and exchange/DSLAM) to select only bins which are usable on the line thus effectively obtaining the best overall bit rate from the line at any given moment in time. With COFDM, a combined signal containing many frequencies (for each bin) is transmitted down the ...

G.lite is designed to not require the use of a DSL filter. G.lite is a modulation profile which can be selected on a DSLAM port by an ADSL provider and provides greater resistance to noise and tolerates longer loop lengths (DSLAM to customer distances) for a given bandwidth. Most ADSL modems and DSLAM ports support it, but it is not a typical ...
802.5 Token Ring can support frames with a 4464-byte MTU, FDDI can transport 4352-byte, ATM 9180-byte and 802.11 can transport 7935-byte MTUs. The IEEE 802.3 Ethernet standard originally mandated support for 1500-byte MTU frames, 1518 byte total frame size (1522 byte with the optional IEEE 802.1Q VLAN/QoS tag). The IEEE 802.3as update ...
The default TCP Maximum Segment Size is for IPv4 is 536. For IPv6 it is 1220. [1]: §3.7.1 Where a host wishes to set the maximum segment size to a value other than the default, the maximum segment size is specified as a TCP option, initially in the TCP SYN packet during the TCP handshake.
The modem connects to a single computer or router, through an Ethernet port, USB port, or is installed in a computer PCI slot. The more common DSL router is a standalone device that combines the function of a DSL modem and a router, and can connect multiple computers through multiple Ethernet ports or an integral wireless access point. Also ...
The WRT54G3G/WRT54G3GV2 Mobile Broadband routers are variants that have four Fast Ethernet ports, one Internet wired port (For DSL/Cable connections), plus a PCMCIA slot for use with a Cellular Based PC Card "aircard". The V2 model has two additional USB ports for 3G modem use and one other USB port, which has yet to be put to use.
