VisuaLink 128/VisuaLink 384
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. If
advance notice is not feasible, you will be notified as soon as possible. When you are notified, you will be
given the opportunity to correct the problem and informed of your right to file a complaint with the FCC.
In the event repairs are ever needed on your Visualink 128 or VisuaLink 384, they should be performed by
NEC America, Inc. or an authorized representative of NEC America, Inc. For information contact:

CSA Requirement
To ensure that certified equipment is attached correctly, and only to the networks of participating carriers, the
following statement shall accompany each unit of certified equipment offered for sale. This statement must be
included conspicuously in written or electronic format, at or near the front of each copy of the operating
manual, or accompany other technical information, or be included as a separate sheet. The required statement
is:
CP-01, Issue 8, Part I
Section 14.1
NOTICE
: The Industr y Canada label identifies certified equipment. This certification means th at the
equipment meets certain telecommunications network protective, operational and safety requirements as
prescribed in the app ropri ate Terminal Equipment Technical Requirements document(s ). The Dep artment does
not guarantee the equipment will operate to the user's satisfaction.
Before installing this equipment, users should ensure that it is permissible to be connected to the facilities of
the local telecommunications company. The equipment must also be installed using an acceptable method of
connection. The customer should be aware that compliance with the above conditions may not prevent
degradation of service in some situations.
Repairs to certified equipment should be coordinated by a representative designated by the supplier. Any
repairs or alterations made by the user to this equipment, or equipment malfunctions, may give the
telecommunications company cause to request the user to disconnect the equipment.
Users should ensure for their own protection that the electrical ground connections of the power utility,
telephone lines and inte rnal metal lic water pipe s ystem, if pres ent, are conn ected togethe r. This precaution may
be particularly important in rural areas.
CAUTION:
Users should not attempt to make such connections themselves, but should contact the
appropriate electric inspection

1.1 Summary
VisuaLink is equipped with a serial external control port that enables a control from a console such as a
personal computer.
The V isuaLi nk execute s a command a nd retur ns a res ponse base d on the i nputting of a command that co nsist of
4 characters or one character and three numbers.
1.2 Communication Outline
Communication protocol between the VisuaLink and a console are consisted of the following:
[1] Command: A protocol issued by a console executes a process on VisuaLink.
[2] Response: A protocol that issues a result for a command to a console. It is always issued at a command
reception. Responses are normal ending response and error response.
[3] Report: When a status is changed inside VisuaLink, a change notice such as an alarm is issued to a
console. Message protocol is issued independently from a command.

1.3 Physica l/Electrical lnterface
The external control port is at the back of the VisuaLink and uses DIN8 pin connectors. The maximum length
of the control cable shall be no more than 20 ft. (6.1 meter) due to electric characteristics. Connector pin
positions are as follows:
NO Name Direction Features
1 RS OUT Request to Send
2CS IN Clear to Send
3 SD OUT Send Data
4 GND - Signal Ground
5 RD IN Receive Data

Stop Bit: 1 bit
Parity: Even, Odd, NONE parity
Baud: 1200, 2400, 4800, 9600bps
Note:
Default setting for VisuaLink is 9600, 8, none, 1.
To change the default setting use the SSPR command.
A: Connect termin al to VisuaLink Serial 2
B: Set terminal application to:

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. When an
error response is received, it analyzes the error contents and sus pends the command issuance or reissues
a command.
