commonly installed technical variety of DSL. DSL
service is delivered simultaneously with regular
telephone on the same telephone line. This is
possible because DSL uses a higher frequency.
EoA
Ethernet-over-ATM
EoA protocol is commonly used to carry data between
local area networks that use the Ethernet protocol and
wide-area networks that use the ATM protocol. Many
telecommunications industry networks use the ATM
protocol. ISPs that provide DSL services often use
the EoA protocol for data transfer with their customers'
DSL modems.
IGMP
Internet Group
Management Protocol
IGMP is a communications protocol used to manage
the membership of Internet Protocol multicast groups.
IGMP is used by IP hosts and adjacent multicast
routers to establish multicast group memberships.
IPoA
Dynamic IP over ATM
IPoA interfaces carries IP packets over AAL5. AAL5
provides the IP hosts on the same network with the
data link layer for communications. In addition, to
allow these hosts to communicate on the same ATM
networks, IP packets must be tuned somewhat. AS
the bearer network of IP services, ATM provides high
speed point-to-point connections which considerably
improve the bandwidth performance of IP network.
On the other hand, ATM provides excellent network
performance and perfect QoS.
MSCV
Manufacture's Concurrent
Software Version
MCSV is the original factory version and remains even
after upgrading the router in the field. This is for
internal identification purposes.
NAT
Network Address
Translation
NAT is the process of modifying network address
information in datagram (IP) packet headers while in
transit across a traffic routing device for the purpose of
remapping one IP address space into another.
PCR
Peak Cell Rate
PCR in kbps: The maximum rate at which you expect to
transmit data, voice and video. Consider PCR and
MBS as a means of reducing latency, not increasing
bandwidth.
Port-Based VLAN
Known as Static VLAN
Static VLAN assignments are created by assigning
ports to a VLAN. As a device enters the network, the
device automatically assumes the VLAN of the port. If
