TYPE OF SERVICE

The VisuaLink 128 and the VisuaLink 384 are stand-alone devices that allow multimedia conferencing by transmitting video, a udi o an d dat a t o r emote locations over the ISDN Basic Rat e in terface. The VisuaLink 128 and VisuaLink 384 connect to the ISDN digital network through separately-registered NTI equipment. They provide POTS ports which allow a customer-provided 2500-type telephone access to the digital network.

This equipment complies with Part 68 of the FCC Rules. The equipment label will appear on the rear exterior panel of the unit and will provide the FCC Registration Number, NEC trade name, model number, serial number or date of manufacture and the country of origin.

TELEPHONE COMPANY PROCEDURES

The goal of the telephone company is to provide you with the best service it can. In order to do this, it may occasionally be necessary for them to make changes in their equipment, operations, or procedures. If these changes might affect your service or the operation of your equipment, the telephone company will give you notice, in writing, to allow you to make any changes necessary to maintain uninterrupted service.

If you have any questi ons about your tele phone lin e, such as h ow many piece s of equip ment you can connect t o it, the telephone company will give you notice, in writing, to allow you to make any changes necessary to maintain uninterrupted service.

In certain circumstances, it may be necessary for the telephone company to request from you concerning the equipment which you have connecte d to your telephone line. Upon request of the telep hone company, provide the FCC registration numbe r and the ri nger equivalen ce number (REN) of the equi pment which i s connected to your line; both of these items are listed on the equipment label The sum of all of the REN's on your telephone lines should be less than five in order to assure proper service from the telephone company. In some cases, a sum of five may not be usable on a given line.

IF PROBLEMS ARISE

If any of your telephone equipment is not operating properly, you should immediately remove it from your telephone lines, as it may cau se harm to the tele phone ne twork. If the telephon e company not es a prob lem, they may temporarily discontinue service. When practical, they will notify you in advance of this disconnection.

1.5 Communication Procedure

There is no procedure for communication between a console and VisuaLink as a rule. Therefore, a communication line is pr esumed to be error-free. When it is remotely operat ed with a mode m, efficient operation may not be expected when a line error occurs. Because of this, in a remote control, a modem with error correction feature shall be used, or VisuaLink shall be checked for operation.

Command/Response Procedure

VisuaLink transmits a confirmation on whether a command is received and the process is completed. After sending a command, please always analyze the transmitted response before issuing a next command. If the next command is issued before a response, an error response such as ''currently processing'' may be returned.

PC Console VisuaLink

Command 1

Response

Command 2

Response

(1) Command 1 is issued using the external control port rather than a personal computer. (2) Analysis of a received command (parameter error, etc.) is implemented. (3) After an analysis, if it is normal, a normal response is transmitted to a personal computer after

transmitting to the remote in communication. However, if it is error response, the error shall be

analyzed, and a command shall be either suspended or re-issued.

(4) After verifying that Response 1 is normal, issue Command 2.

Note:

After issuing a command from a console, if an alarm emits in VisuaLink, an alarm report may be

transmitted before a response to the command.

Abnormal Handshake Procedure

When the VisuaLink receives a report command from a remote unit at a time the VisuaLink is sending a command to the remote unit in communication, the VisuaLink transmits an indication to a PC using the external control port and then transmits a command to the remote unit.

Command 1

Chapter 1 VisuaLink 128/384 Engineering Guide

(1) Command 1 is issued using the external control port rather than a personal computer. (2) If a report is received from the remote unit before a transmission of Command 1, it transmits a report to

a PC and then transmits C ommand 1 to th e remote unit. It transmits R esponse 1 to the PC after t he transmission. However, in parameter error and etc., it immediately transmits an error response.
