Cisco 776 - 776 Router - EN Manual de usuario descargar pdf (Pagina 4)

successfully exchanged video

with an outside client. No

audio signals were exchanged.

With NetMeeting, the operation

of the client was intermittent.

Using CU-SeeMe, incoming

calls were not accepted. Once a

default workstation’s IP address

was configured on the NET-

GEAR RT328 ISDN Router,

an incoming call was accepted;

however, the client behind

the router did not receive a

video signal.

Ramp Networks says the

WebRamp 410i currently

supports CU-SeeMe versions

up to 3.0. When using CU-

SeeMe, clients behind the

WebRamp 410i were unable to

receive video from their remote

partners. No audio signals were

exchanged and incoming calls

were not accepted. The

WebRamp 410i currently

supports CU-SeeMe versions

up to 3.0.

Graphical User

Interface (GUI)

Evaluation

When compared to competing

ISDN routers, 3Com’s LAN

Modem required the fewest steps

when configuring a basic

Internet connection using the

GUI. Configuration of the 3Com

LAN Modem was facilitated by

a built-in HTML Web server,

embedded in firmware, which

allows the device to be managed

in-band from any network sta-

tion equipped with a standard

Web browser. Test results show

that the 3Com LAN Modem’s

browser-based GUI can be used

to configure all of the features

tested. See figure 2.

The Pipeline 75, Cisco 776

ISDN Access Router and NET-

GEAR RT328 ISDN Router

required the installation of pro-

prietary GUI software on the

management station. These

products do not offer GUI

support for all features tested.

Ascend did not offer technical

support for the Pipeline 75’s

GUI; Ascend recommends con-

necting the unit to a PC with

either a serial or crossover

Ethernet cable and running a

command line interface (e.g.

Hyper Terminal, Telnet).

The Pipeline 75 GUI consists

of separate setup and monitor

utilities. Data call parameters

for the Pipeline 75 are available

through the Monitor GUI.

Manual calling for the Pipeline

75 is supported through the

command line only. The Cisco

776 ISDN Access Router has

two GUI interfaces: FastStep

and ConfigMaker. Both offer

support for setup, configuration

and monitoring. The Tolly

Group tested the FastStep

utility. Configuration of NAT is

supported on the Cisco 776

ISDN Access Router but the

user must step through the

FastStep utility in order to

enable or disable it. FastStep

does not allow a user to view

workstation settings; however,

subsequent to the completion of

testing, Cisco said that such

functionality is available in

CiscoView and Resource

Manager Essentials. The Web

Ramp 410i supported all the

features tested through its

HTML browser interface.
