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, audio and data to remote locations over the ISDN Basic Rate interface. 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 questions about your telephone line, such as how many pieces of equipment you can connect to  
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 connected to your telephone line. Upon request of the telephone company, provide  
the FCC registration number and the ringer equivalence number (REN) of the equipment which is 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 cause harm to the telephone network. If the telephone company notes a problem, 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:

1.5 Communication Procedure  
There is no procedure for communication between a console and VisuaLink as a rule. Therefore, a  
communication line is presumed to be error-free. When it is remotely operated with a modem, 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.

Command 2  
Response  
(1)  
(2)  
(3)  
Command 1 is issued using the external control port rather than a personal computer.  
Analysis of a received command (parameter error, etc.) is implemented.  
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.

(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 Command 1 to the remote unit. It transmits Response 1 to the PC after the  
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 suspends the command issuance or reissues  
a command.

SCPI  
Setting/Checking Video Priority  
1-11  
Description:  
The VisuaLink has a function to automatically optimize the picture quality,  
(e.g., number of frames, resolution, coding, noise, etc.). In low bit rate  
coding there is characteristic for resolution and frame to oppose each other.  
If resolution is imposed, the number of frames (motion) becomes less. If  
however the number of frames increases, resolution quality is degraded.  
This requires a trade off.

Description:  
Sets audio delay (lip sink). Delay is generated when video is coded in  
transmission, and the amount of delay differs depending on a transmission  
speed. On the contrary, audio coding delay is about 1/1000 ~ 1/100, so a  
problem that a person’s lips and audio cannot be synchronized (lip sink).  
VisuaLink is equipped with a feature to insert a delay in audio to  
compensate lip sink by adjusting a mount of delay.

Appendix C  
Appendix C: ISDN Q.931 Cause Code Definitions  
The following table defines the Q.931 cause codes that the VisuaLink 128/384  
writes to event files. Q.931 specification defines the layer-3 protocol for two  
connected ISDN devices.  
Table C: ISDN Q.931 Cause Code Definitions  
Code  
Meaning  
Explanation  
The requested destination can not be reached because the number  
is not currently assigned.  
1
Unallocated (unassigned) number  
No route to specified transit network  
No route to destination  
The route to the destination network is not recognized, either  
because it does not exist or because it does not serve the equipment  
sending the message.  
2
3
8
The network through which the call has been routed does not serve  
the desired destination.  
A call is being cleared because the B-channel is being preempted for  
a call of higher priority. If the preempted B-channel is not needed for  
the preempted call, it is released for prior use.  
Preemption  
A call is being cleared because the B-channel is being preempted for  
a call of higher priority. The B-channel is dedicated to the preempted  
call.  
9
Preempted - circuit reserved for reuse  
16  
17  
Normal call clearing  
User busy  
A call is being cleared at the request of one of the users.  
The user line is busy.  
No alert or connect indication was received within the prescribed  
period of time.  
18  
19  
21  
22  
No user responding  
No answer from user (user alerted)  
Call rejected  
Connection has not been established in the specified time period,  
and an alert has been received. (Internal network timers may  
generate this cause.)  
The call was rejected despite the equipment being compatible and  
not in use.  
The number of the called party is no longer assigned: the new  
number may be reported in the message. Cause code 1 is assigned  
if the network does not support this function.  
Number changed  
A signaling message could not be delivered to the user, indicating  
that the interface to the destination is not functioning correctly.  
27  
28  
Destination out of order  
Invalid number format (address  
incomplete)  
The user cannot be reached because the number is incomplete or in  
the wrong format.  
30  
31  
Response to STATUS ENQUIRY  
Normal, unspecified  
A message has been received in response to a STATUS ENQUIRY.  
A normal event has occurred for which no other cause applies.  
No appropriate circuit or channel is currently available to handle the  
call.  
34  
No circuit/channel available  
41  
42  
Temporary failure  
The network is temporarily not functioning correctly.  
Switching equipment congestion  
The switching equipment is experiencing a period of high traffic.
