TANDBERG GW Dataport Command Interface User Guide
D13202 Rev 01 3
1. Introduction
The TANDBERG GW Dataport Command Interface User Guide contains guidelines on how
to use the textual command interface supported by the GW. The Dataport Command Interface
can be accessed through Telnet via the LAN interface or through RS-232 by connecting a
serial cable to the serial interface connector, referred to as the Dataport (ref. chapter 2). Three
Telnet sessions can be connected to the GW at the same time in addition to the RS-232
connection.
If, after reading this manual, you require additional information concerning the use of the
TANDBERG GW Dataport Command Interface, please contact your local TANDBERG
dealer who will be able to supply you with relevant information for special applications.

2. Connecting to the Dataport Command Interface through the
RS-232 port.
The RS-232 port is a 9-pin, female, D-sub connector located on the back of the GW. The port
is configured as a DCE (Data Communications Equipment). The RS-232 port is default set to
9600 baud, 8 databits, none parity and 1 stopbit from factory. The RS-232 port is also referred
to as the Dataport.
2.1. Hardware And Cabling
The pin outs for the RS-232 are defined in the following table (the DTE, Data Terminal
Equipment, could be a PC or other device capable of serial communication).
Pin no Signal Description Direction
1 CD Carrier detect To DTE
2 RD Receive data To DTE
3 TD Transmit data From DTE
4 DTR Data terminal ready From DTE
5 Ground
6 DSR Data set ready To DTE
7 RTS Ready to send From DTE
8 CTS Clear to send To DTE
9 RI Ring indicator To DTE
NOTE! A straight through cable should be used between the TANDBERG GW’s RS-232 port
and the DTE.
The figure below illustrates the recommended cable-wiring scheme for connecting the GW to
a PC through RS-232.
DTR and RTS are ignored. DSR, CD, and CTS are always asserted, while RI is not used.
TANDBERG GW PC
DCE, 9 pin DTE, 9 pin
1 CD 1 CD
2 RD 2 RD
3 TD 3 TD
4 DTR 4 DTR
5 GND 5 GND
6 DSR 6 DSR
7 RTS 7 RTS
8 CTS 8 CTS
9 RI 9 RI

2.2. Configuring The Dataport From The Web Interface
Click on System Configuration tab and then the Dataport button. The Dataport can be
configured by setting baudrate, parity, databits and stopbits.
2.3. Troubleshooting
If communication cannot be established between the PC/terminal and the TANDBERG GW’s
Dataport the following should be checked:
•Verify that the serial cable is a straight through 9-pin to 9-pin cable
•Confirm that the configuration of the PC/terminal’s serial RS-232 port is identical to
the configuration of the TANDBERG GW RS-232 port.
•Verify that the PC/terminal’s serial RS-232 port is working properly by connecting it
back-to-back to another PC/terminal and send characters in both directions1.
1It requires a null-modem cable to perform this test

3. Connecting to the Datport Command Interface using Telnet
The TANDBERG GW has two LAN ports. Connection to the Dataport Command Interface
via Telnet should be done through LAN port 1.
The GW’s Telnet server provides access to the Dataport Command Interface through a 10/100
base T network interface supporting the TCP/IP protocol.
When connected to the GW, the Telnet client will receive a welcome message similar to the
following:
Welcome to TANDBERG
TANDBERG GW Release G1.0
SW Release Date: 2003-07-01
NOTE! If the TANDBERG GW is protected by an IP password you will be prompted to enter
this password before you can access the Dataport Command Interface via Telnet.

4. The TANDBERG GW Commands
4.1. Introduction
Typing ‘?’ or ‘help’ when connected to the Dataport Command Interface will return a list of
valid commands. The commands are used to control the functions of the GW. A command
may be followed by a set of parameters and sub-commands. This chapter gives a description
of the valid commands for the GW.
4.1.1. Command format
Typing ‘?’ or ‘help’ after a command will result in a usage text being displayed. Usage text
gives information about the command format, i.e. valid parameters, sub-commands etc. An
example is shown below (the user input is shown in bold).
prichan ?
usage: prichan <PRI interface> max <number>
or: prichan <PRI interface> high <number>
or: prichan <PRI interface> low <number>
or: prichan <PRI interface> search <high/low>
-
PRI interface - a/b/c/d
number : 1..23
Parameters are arguments upon which the command will operate. Required parameters are
denoted by: < >, while optional parameters are denoted by: [ ]. The possible values for a given
parameter are separated with slashes ( / ). For some parameters, only the parameter name is
supplied within the brackets. In these cases a specific parameter value is to be substituted for
the parameter name. The possible values to be substituted for a parameter name are often
supplied below if it is not obvious what the possible values are.
Sub-commands are commands grouped together within a command. Different sub-commands
within a command may have different parameter sets. In the example above: max, high, low,
search are sub-commands to the command prichan.
NOTE! The Dataport Command Interface is not case sensitive.
4.1.2. Command types
The commands can be divided into three major classes:
•System Commands
•Parameter Setting Commands
•Status Commands
System Commands are commands that initiate processes in the GW. E.g.: The command
calltransfer initiates the process of transferring a call.
If the command is not syntactically correct, the GW returns ERROR. If the command is
syntactically correct, but the system is not accepting the command, *R response feedback is
issued followed by ERROR. If the command is syntactically correct and the command is
accepted, the GW returns OK. An example of *R response feedback is shown below in the

TANDBERG GW Dataport Command Interface User Guide
D13202 Rev 01 8
case where the user is trying to transfer a call from an inactive GW port (the user input is
shown in bold).
calltransfer 1 999999
*R Invalid gateway id
ERROR
Parameter Setting Commands are commands that set a system parameter to a specific value.
E.g.: The command ippassword sets the valid password needed to establish an IP connection
with the GW to a specific value.
If the command is syntactically correct the GW returns OK, otherwise the GW returns
ERROR. If *P parameter feedback is activated (ref. command feedback), and the parameter
is successfully changed, the GW will return the command with the new value. An example of
*P parameter feedback is shown below (the user input is shown in bold).
pardial on
OK
*P pardial on
When issuing a Parameter Setting Command with no parameter, the GW will return the
command with the current setting. E.g.:
pardial
*P pardial on
OK
Status Commands are commands that list different sets of system parameters. If *S status
feedback is activated (ref. command feedback), status commands are automatically called
when corresponding parameters are being changed.
4.2. The commands
The commands are divided into five groups: System Configuration Commands, General GW
Commands, System Status Commands, Debug Commands and Special Commands.

TANDBERG GW Dataport Command Interface User Guide
D13202 Rev 01 9
4.2.1. System Configuration Commands
Command: Description:
defvalues set This command is used to restore factory default settings. Issuing this command with
no parameters will restore all settings except network settings and option key.
To reset all values to factory defaults the optional parameter all or *factory should
be added. Please download the parameter file, or write down the optionkey before
you execute this command (issue the command optionkey to view the current value
of the optionkey).
defvalues set [all/factory]
* Adding the optional parameter factory, the eeprom will be erased and the flash
disk will be formated.
h323gatekeeper Sets gatekeeper parameters.
NOTE! H.323 services must be set before the GW can be registered to a gatekeeper,
ref. command gwh323service.
h323gatekeeper <on/off>
or
h323gatekeeper address <ipaddress>
---
sub-commands:
•address: Sets the IP address of the gatekeeper
Example of h323gatekeeper feedback:
*P h323gatekeeper on
*P h323gatekeeper address 10.0.0.30
ipaddress Configures the LAN interfaces when static IP address allocation is used (the
command ipassignment is used to select between DHCP and static IP address
allocation).
NOTE! The GW needs to reboot before the changes will apply.
ipaddress [LAN interface] static <ipaddress>
or
ipaddress [LAN interface] subnetmask <ipaddress>
or
ipaddress [LAN interface] gateway <ipaddress>
---
parameters:
•LAN interface: 1. Number identifying the LAN interface. If this
parameter is omitted the command applies to all interfaces (only interface
1is in use).
sub-commands:
•static: Sets the static IP address for the given LAN interface.
•subnetmask: Sets the subnet mask variable for the given LAN interface.
Subnet mask defines the network class. If the setting is 255.255.255.0 the
local network will support up to 256 nodes, denoting a class C network. If
the setting is 255.255.0.0 the local network is a class B network with
65536 addressable nodes.
•gateway: Sets the gateway IP address for the given LAN interface. If a
gateway is located on the LAN and the GW needs to reach nodes through
this gateway, the gateway address can be set using the gateway variable
(the IP address of the gateway will be set automatically if the GW is in
DHCP mode)

TANDBERG GW Dataport Command Interface User Guide
D13202 Rev 01 10
Example of ipaddress feedback:
*P ipaddress 1 static 10.0.5.98
*P ipaddress 1 subnetmask 255.255.0.0
*P ipaddress 1 gateway 10.0.0.1
ipassignment Selects between DHCP (Dynamic Host Configuration Protocol) or static IP address
allocation. When DHCP is selected the GW will automatically receive all the
necessary information from the DHCP server. This function should be used when
the GW is connected to a LAN using DHCP. When using this mode, IP-address and
IP-subnet mask are not used because the DHCP server supplies these parameters.
ipassignment [LAN interface] <dhcp/static>
---
parameters:
•LAN interface: 1. Number identifying the LAN interface. If this
parameter is omitted the command applies to all interfaces (only interface
1is in use).
Example of ipassignment feedback:
*P ipassignment 1 static
ipmtu Sets the maximum IP packet size to be used for H.323 calls. It can be useful to
reduce the packet size when packets are transmitted over links that add overlay
(f.ex. VPN). Reducing the packetsize will prevent the packets from being
fragmented.
ipmtu <1200-1400>
Example of ipmtu feedback:
*P ipmtu 1400
ippassword Sets a password to restrict access to the GW’s webserver, telnet and ftp resources.
ippassword [LAN interface] <password>
---
parameters:
•LAN interface: 1. Number identifying the LAN interface. If this
parameter is omitted the given value is set for all interfaces (only interface
1is in use).
•password: Textstring of maximum 16 characters. If the password is
forgotten it can be deleted using the command ippassword “” through the
RS-232 port.
NOTE! The default password is “TANDBERG”.
ipspeed Sets LAN port speed.
NOTE! The GW needs to reboot before the changes will apply.
ipspeed [LAN interface] <speed>
---
parameters:
•LAN interface: 1. Number identifying the LAN interface. If this
parameter is omitted the given value is set for all interfaces (only interface
1is in use).
•speed: auto/10half/10full/100half/100full. The speed is either set to auto
or manually from 10mb half duplex to 100mb full duplex. When set to
auto the GW will automaticall

ipqos Configures the different Quality of Service (QoS) algorithms supported by the
TANDBERG GW. QoS are used to set priority on QoS enabled IP networks.
ipqos prectlph <chantype tlph> <precvalue>
or
ipqos diffstlph <chantype tlph> <diffsvalue>
or
ipqos precvtlph <chantype vtlph> <precvalue>
or
ipqos diffsvtlph <chantype vtlph> <diffsvalue>
or
ipqos mode <precedence/diffserv/off>
or
ipqos tos <delay/throughput/reliable/cost/off>
or
ipqos rsvp <auto/off>
---
parameters:
•chantype tlph: audio/signalling. Indicates which channel type the setting
applies to.
•chantype vtlph: audio/video/data/signalling. Indicates which channel
type the setting applies to.
•precvalue: 1-7/auto/off. The priority value to be used for IP Precedence.
When set to auto the system will use the Cisco recommended values. For
video telephony calls this value is 6 for signalling channels and 4 for audio
channels and video channels.
•diffsvalue: 0-63. The priority value to be used for Differentiated Services
(DiffServ).
•modevalue: ipprecedence/diffserv/off. Possible priority algorithms.
•tosvalue: delay/throughput/reliable/cost/off. Possible routing priority
values.
sub-commands:
•prectlp: Sets IP Precedence value to be used for voice over IP calls.
•diffstlph: Sets the Differentiated Services (DiffServ) value to be used for
voice over IP calls. DiffServ is an extension of IP Precedence and enables
division of IP traffic into 63 classes with different priority. Should be used
instead of IP Precedence if possible.
•precvtlph: Sets IP Precedence value to be used for video over IP calls.
•diffsvtlph: Sets the Differentiated Services (DiffServ) value to be used for
video over IP calls.
•mode: Sets which priority algorithm to be used.
•tos: Sets the routing policy the router should use when routing a call. If
supported by the router, the endpoint can signal to the router to select a
route that gives: “Minimum delay, maximum throughput, maximum
reliable or minimum cost.
•rsvp: Sets the Resource Reservation Protocol (RSVP) to on or off. When
RSVP is set to on, the TANDBERG GW will signal to the network the
minimum bandwidth and minimum delay required to make a call. RSVP
will try to reserve the resources required. If granted, Quality of Service
will be ensured during the whole call.
NOTE! The network has to be RSVP enabled to use this protocol
