RIP 1 and RIP 2 allow routers to exchange routing information. The T1
Access Router then uses this information exchange to build routing tables for
IP Packet routes. After building the routing tables, the T1 Access Router
periodically broadcasts the contents to neighboring routers so your network
can choose the most efficient routes available.
OSPF uses link-state routing algorithms to calculate routes based on the
number of routers, transmission speeds, delays, and route costs. Using the
OSPF protocol, the T1 Access Router works with other routers in your
telecommunications fabric to dynamically change routing “on the fly” to make
use of the most efficient and cost-effective transit across your network.
Dynamic Host Communications Protocol (DHCP) uses a client-server
architecture to assign IP addresses to PCs and workstations on the LAN. The
DHCP server dynamically assigns these IP addresses, which can be either
temporary or permanent, to each PC or workstation (DHCP client). These IP
addresses are “housed” on the DHCP server.
Network Address Translation (NAT) enables an enterprise to set up two sets
of IP addresses
−
one set for LAN traffic and another for Internet traffic. This
can provide a layer of security by eliminating outside access to internal IP
addresses from the Internet.
Bridging separate LANs together is another option for the IP traffic. Using the
IEEE Standard 802.ID Transparent Bridging specification, the T1 Access
Router lets you bridge separate LANs across a WAN so they operate as a
single LAN.
The T1 Access Router gives service providers and enterprise customers the
capability to monitor end-to-end network performance as well as the
capability to verify SLAs; isolate performance problems to the LAN, local
loop, or frame relay network; determine appropriate bandwidth needs; and
monitor network trends to aid in future capacity planning.

Performance
Historically, WAN access devices have tended to perform well as
single-function devices such as CSUs/DSUs, but have not been optimized to
address higher level traffic issues such as service levels and integration.
Verilink's architecture and Web-based user interface work together to address
all access issues as services and applications, rather than as circuits and
protocols, for exceptional WAN management performance.
To further leverage its Web browser interface, Verilink's new architecture also
allows firmware to be upgraded via the Web from a standard browser, with
password control, if desired.
