DV-201DM for H.323 & SIP

3.6. VoIP Function

H.323 protocol provides voice service through IP network by way of sending digital voice-data packetized and encoded via IP network to process its calls. This function is complied with ITU-T : H.323 Recommendation.

SIP is a text-based protocol that is based on HTTP and MIME, which makes it suitable and very flexible for integrated voice-data applications. SIP is designed for real-time transmission, uses fewer resources and is considerably less complex than H.323. Its addressing scheme uses URLs and is human readable.

3.7. TCP/UDP/IP Protocol Processing Function

TCP/UDP/IP Protocol Processing Function processes various Protocols like TCP complying with RFC793, UDP with RFC768 and IP Protocol with RFC791.

2 How to install S/W

2.1 PC configuration

After installing system according to service network diagram of 1.2, access the equipment using Telnet or Web browser, you should assigned IP address anywhere between 192.168.1.1 and 192.168.1.253.

In next paragragh, we describe how to configure dynamic IP when DHCP server function is activated. In 2.1.1 paragragh, we describe how to configure static IP according to user’s network environment.

2.1.1 Configuring Dynamic IP

DV-201DM supports DHCP server function to assign private IP to PC. Our software enables users to use DV-201DM in a Dynamic Network environment.

1. Open “Control Panel” and double click “Network and Dial-up connection” icon.

2 - 10

2. Double click “Local area connection” in network connection window.

3. Click on “Properties” button.

DV-201DM for H.323 & SIP

6. Click “OK” button in internet protocol attribute window and then close all

windows opened.

7. Open “COMMAND PROMPT” window and Execute “ipconfig” command to

make sure that your PC is assigned IP address, subnet mask and default gateway value.

(Verify: IP address range is between 192.168.1.10 ~ 192.168.1.29 )

Remember the IP Address value should be in 192.168.1.1~ 192.168.1.253,

subnet mask should be 255.255.255.0, and Default Gateway should be

192.168.1.254.

2.1.2 Force Static IP

If your PC was not assigned IP information after the procedure above, you can manually assign IP information by doing the following. From above, follow steps 1 through 4 then follow the procedures below.

1. Choose “Use the following IP address”, enter IP address, subnet mask, Default gateway. If static IP is configured in DV-201DM, also enter DNS server information.

IP address : any address of 192.168.1.1

through 192.168.1.253 Subnet mask : 255.255.255.0 Default gateway : 192.168.1.254

Note : When DV-201DM is allocated IP by DHCP protocol, input the value and

confirm DNS server address.

2. Click “OK” button, and close all windows.

2.3.1 Basic Commands

DIR (or LS)

“dir” is the same command as “ls” and displays the executable commands and sub-directory which can be run in the current directory. The sub-directory is displayed with “/” added after the last character to differentiate from the executable commands. The following example is the result after executing “dir” command on DV_GW> prompt, where DV_GW is system name. The capitalized letters in the directory name and command name is the minimum number of characters to be entered in changing a task directory or executing a command and they are used as abbreviations for a directory or a command.

DV-201DM for H.323 & SIP

[Example]

DV_GW> dir © SYstem/ COnfig/ Ftp_client/ Test/ Netutil/ STatistics/ Vocfile/ Debug/ Memory/

"cd" is a command to change the working directory. A directory you want to move can be given an direct path starting from a route directory or given a relative path based on the current directory. It is possible to change directory by typing the name of directory without “cd” command or by typing capitalized character of name of destination directory. Same results are displayed in case of typing “cd system” or in case of typing “system” or in case of typing “s” (minimized letter of destination directory “system”). If only “cd” without any character is typed, they can see root directory. The following example is an after executing “cd” command on root directory.

[Example]

DV_GW> cd system © DV_GW/SYSTEM>

1. Hardware Installation & Cable connection z Place on flat surface and make sure that rubber feet are attached. (for cooling system) z Following figure shows the cable’s connections

2. System Configuration CAUTION : In system configuration procedure at start, please eject a PSTN line cable.

z System configurations of DV-201DM consist of following 2 parts.

- Internet setting : For PPP Connection, consist of the ISP phone number, user ID and password.

- VOIP setting : For Internet telephony, you should set Proxy Server or Gatekeeper and telephone number and so on.

z You can configure by using a telephone connected to TEL port and Web browser of your PC. Configuration by telephone can be applied if you can not connect to DV201DM by web browser. We recommend using Web browser.

- Using telephone : please refer page 2-49,50. z When you have configured system. Please inject a PSTN line. Make restart DV- 201DM by power switch and wait about 20~30 seconds until system is initialized.

APPENDIX A How to use modem script

Caution : You don’ t have to modify modem script of DV-201DM in most of environments. If your modem script is wrong, DV201DM don’ t operate right. So when you modify modem script, be careful.

1. Overview

In DV-201DM, the script is provided for modem and PPP connection. In the script of DV-201DM, loop and decision phase is not included, and user can configure the minimal scenario for configuring modem & controlling PPP connection. In DV-201DM, as the followings, two types of script are provided.

1) Setup script

Initialize & configure internal modem in DV-201DM.

2) Dial script

Configure the procedure of calling & PPP connection.

The follows is the initial value of script in DV-201DM.

Setup ₩N AT&F OK AT+GCI=61 OK ATTX4W1L3M1E0S95=47 OK AT₩₩N3B0 OK ₩N Dial ₩N ATD₩T CONNECT ₩N

2. Operation of sript

The script of DV-201DM is divided according to space character and consisted of receiving expectation character column and transmitting character column. The script of above box can be divided into each character column and is as the follows. The bold character is a receiving expectation character column.

1) Setup script

₩N - no receiving expectation character column AT&F - initialize modem OK - response of modem regarding to initializing modem AT+GCI=61 - assignment country code OK - completion of assignment country code ATTX4W1L3M1E0S95=47 - configuration operation of modem OK - completion of configuration operation of modem AT₩₩N3B0 - configuration the second operation of modem OK - completion of configuration the second operation of modem ₩N - no receiving expectation character column

2 - 53

DV-201DM for H.323 & SIP

2) Dial script

₩N - no receiving expectation character column ATD₩T - calling command CONNECT - completion of connection ₩N - no receiving expectation character column

In DV-201DM, there are the reserved character columns for special function. The reserved character columns are opened with “ ₩” character and the reserved length is different according to the follow character. So be careful.

The reserved character columns are as follows.

character argument description example

s - Space character (SP) A₩sBC

t - Tab character (TAB) A₩tBC

n - Line feed (LF) A₩nBC

r - Carriage return (CR) A₩r₩BC

₩ - Back slash (₩) ₩₩N3

d ‘ 0’ ~’ 9’ Transmitting delay (Delay) A₩d2BC

c - Not included opening character +++₩c T - Replacement character column with dialing

number (TEL)

U - Replacement character column with user ID

(USER)

P - Replacement character column with password

(PASSWORD)

N - NULL (no character column) ₩N

In DV-201DM, expansion character columns are supported. The expansion character column is used for comparing “ receiving expectation character column” with “ predefined character column” and it is useful in environment with various expectation character columns.

z &U

It is the expansion character regarding to user input prompt and DV-201DM compare this character column with the following character column.

“ serid:", "ogin:", "userid", "user id", "login", "sername

z &P

It is the expansion character regarding to password input prompt and DV-201DM

ATD₩T

₩U

₩P

2 - 54

compare this character column with the following character column.

“ assword:", "assword?”

z &C

It is the expansion character regarding to command input prompt and DV-201DM compare this character column with the following character column.

"> ", "# " "uthentication fail", "uthentication Fail", "nknown", "ogin incorrect"

3. Script command

In DV201DM, the following command is provided for modification/confirmation of script.
