About the T1 Access Router 1-1
CHAPTER
1
C HAPTER 1 A BOUT THE T1 A CCESS
R OUTER
Introduction
The T1 Access Router is a compact, feature-rich “standard” router designed to
allow small and medium-sized businesses and enterprises with multiple
branch locations to take advantage of lower cost T1 connections. Installed on
the customer’s premises, this powerful router with an integrated CSU/DSU
enables high-speed Internet access and site-to-site communications.
The T1 Access Router boasts management features usually found only in
more expensive routers. The unit supports IP over frame relay, PPP, or
leased-line applications. A superior alternative to conventional high-end
routers, the T1 Access Router connects to the LAN through an autosensing
10/100Base-T Ethernet port, and is equipped with an RS-232 console port for
local management.
All of the T1 Access Router’s installation, performance configuration, traffic
monitoring, alarm reporting, and diagnostic capabilities can be configured
through the unit’s embedded Web server interface using Microsoft®Internet
Explorer™. The Web server interface can be accessed locally through the
Ethernet port or the Supervisory port, or remotely through the Network port.
The unit’s built-in ServiceAware™ technology lets network managers
maximize available WAN bandwidth and verify Service Level Agreements
(SLAs). This management platform lets the end user see network activity
(performance) and problems (diagnostics) on any permanent virtual circuit
(PVC), access line, or physical circuit.
Verilink’s standard FrameStart™ technology eliminates the requirement for
a frame relay test set. Providing benefit from the time of initial frame relay
circuit installation, FrameStart ensures that T1 circuit status, signal quality,
loopback code detection, access link condition, and the various Layer 2 frame
relay investigation and reporting features are available and accurate.
The T1 Access Router supports static routing configurations or dynamic
routing protocols (Routing Information Protocol −RIP 1 and RIP 2 −or Open
Shortest Path First −OSPF).

1-2 T1 Access Router
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.
Features of the T1 Access Router
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.

About the T1 Access Router 1-3
SNMP Management
With integrated SNMP in-band management, enterprise managers can now
manage Verilink units and their integral CSUs/DSUs as a single unit. With
only one LAN segment in the network, all Verilink platforms can be managed
by SNMP. With self-learning functionality, these platforms learn their frame
relay environment and eliminate the need for remote, trained personnel. By
downloading all configuration parameters from the central site, no interaction
is required at remote sites to establish connectivity. WANs can be constructed
using frame relay or leased-line services. Network managers can now fine
tune the enterprise network for the lowest cost and highest performance.
Intelligent WAN Access Architecture
Verilink's next-generation WAN access architecture is built around a
PowerPC™ processor, and works with non-proprietary network management
solutions via SNMP. An embedded Web server supplies a simple-to-use
interface for configuration and statistics collection, with a service table for
mapping services to ports, an endpoint table for configuring and monitoring
service endpoints, and a user table for traffic monitoring and control.
Optional Advanced Network Management
As an option for the T1 Access Router, Verilink offers a network
management system based on RedPoint's NetVoyant™ software, which was
designed to provide IT professionals with the information required to make
informed, enterprise-wide capacity-planning and investment decisions.
NetVoyant is an NT-based element management system that includes an
ODBC-compliant database, CORBA IDLs for customization and flexibility,
real-time diagnostics, and extensive reporting and trending application
support. The solution employs an open-system, multi-vendor support approach
for network management, monitoring, and the collection of statistics from any
SNMP-based networking device, including Verilink equipment already in the
field.
The T1 Access Router extends the functionality of NetVoyant’s software by
incorporating customized configuration modules. This advanced network
management system is offered as an option for the T1 Access Router. Please
contact Verilink for availability and pricing information.
About FrameStart Technology
FrameStart’s integral frame relay circuit installation and diagnostic tools help
reduce equipment and installation costs, simplify configuration setup, and
alleviate frame relay connection uncertainties −all in one unit.
The T1 Access Router supports both FrameStart Install and FrameStart
Monitor modes as well as Layer 2 statistics gathering and diagnostic
capabilities that maximize network availability and manage the growth of the
network.

Front Panel
The front panel of the T1 Access Router (Figure 1.1) provides two
user-activated input control buttons and five LED status indicators that
provide access to unit configuration, diagnostics, and utilities.
Figure 1.1 Front Panel of T1 Access Router
The T1 Access Router’s front panel LED status indicators are defined in the
table below:
Indicator Description
MODE Normally, the MODE indicator lights green.
This indicator lights amber while configuration is being set by
the front panel buttons or when the configuration is changed by
SNMP or through the Web server interface. The indicator will
remain amber until the changed configuration is saved; it will
revert to green when the new configuration has been saved.
NET The NET indicator is off (not illuminated) when the port has not
been configured.
The indicator lights red if the T1 link is down.and all configured
protocols on the link are established.
The indicator lights amber if the DDS link is operational but at
least one configured protocol on the link is down.
