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.

(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.

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.

Requested circuit/channel not available
Resource unavailable, unspecified
Requested facility not subscribed
Outgoing calls barred
The requested circuit or channel is not available.
A resource is unavailable, and no other cause code applies.
The user has not subscribed to the requested service.
The caller is not authorized to make calls.
Incoming calls barred
The recipient has rejected the call.
Bearer capability not authorized
Bearer capability not presently available
Bearer capability not implemented
Channel type not implemented
The user is not authorized to use the requested capability.
The requested capability is not currently available.
The equipment does not support the requested capability.
The equipment does not support the requested channel type.
The equipment does not support the requested supplemental
service.

70
requested facility not implemented
Only restricted digital information bearer
capability is available
The equipment supports only the restricted version of a service
capability.
Service or option not implemented,
unspecified
The service or option is not implemented, and no other cause code
applies.
79
81
Invalid call reference value
The call reference value does not match an existing call.
The requested channel can not be assigned to the call - for example,
channel 13 through 23 have been requested, and the user has
subscribed only to channels 1 through 12.
82
Identified channel does not exist
A suspended call exists, but this call
identify does not
The requested call can not be resumed because it does not
correspond to a suspended call.
83
88
96
97
The requested call can not be accommodated because of protocol
differences or other incompatibilities, such as data rate.
Incompatible destination
The call can not be completed because a mandatory information
element is missing.
Mandatory information element is missing
Message type non-existent or not
implemented
The received message is not a recognized message type.
Message not compatible with call state, or The message can not be received while in the call state.
