RSG (Remote Service Gateway)

1. Overview

Overview

• The LDK-RSG (LDK-Remote Services Gateway) is a remote gateway that provides

a fully transparent connection to the host LDK system over a broadband xDSL or

Cable modem provided by an ISP (Internet Service Provider).

• The broadband connection employs the system’s VOIB channels to communicate

with the LDK-RSG.

• The LDK-RSG transparently extends the host LDK system services and resources

to users with DKTU and SLT interface over the broadband IP network.

6. Interface

WAN Interface

The WAN connection is used for the communication with the LDK System

and other network devices from the local network.

• WAN Interface Type

1. ADSL

-. PPPoE : User name and Password are required

for authentication

2. Static IP (Fixed IP)

3. Dynamic IP(Automatic IP Assignment)

xDSL or Cable Modem

LAN Interface

The LAN connections are used for communicating with

a PC connected to the LAN port of RSG.

• LAN Interface

1. PC or HUB can be connected.

2. Local private network can be configured.

3. DHCP server is supported.

4. Port forwarding allows WAN to access

the internal private LAN.

5. RSG’s LAN default IP Address;

10.10.50.50

TIA/EIA-232 (RS-232) Connection

LDK-RSG can be managed by RS-232C connection .

1. 38400bps, 8 bits, no parity, and one stop bit.

2. No hardware flow control signals.

3. Only three wires are needed (TD, RD, and SG)

CO/SLT/DKTU

For the most of Call features, stations and co lines on RSG is same as local devices.

1. CO

-. Analog CO line from public exchange is connected.

-. In case of the LDK-RSG power failure,

the external SLT port is directly connected

to PSTN

2.SLT

-. Single Line Telephone or Fax Machine

can be connected.

3. DKTU

-. DKTU is connected.

External BGM

1. The BGM jack is used to connect to an external music source.

2. The RSG has one internal and one external MOH source.

3. RSG can use its local MOH source in the RSG.

Alarm

1. When Alarm Signal is detected from RSG,

the LDK system gives the Alarm Ring to

the Alarm assign station in PGM 385.

2. The alarm will be stopped by Alarm Reset code.

External Relay1/2

1. Two dry relay contacts are provided.

2. They can be used for LBC or Door Open.

RSG Setting Procedure on RSG(Fixed IP) 1. baud rate : 38400

2. Set Master’s IP Address (VOIB IP Address) : 1) Press ‘Enter’ Key, the ‘main:>’ shows up after menu list 2) Type ‘system’ and enter. 3) Type ‘set master xxx.xxx.xxx.xxx’. The ‘xxx.xxx.xxx.xxx.’ is IP address. Ex) main:/system> set master xxx.xxx.xxx.xxx 4) Return to ‘main:>’ mode by typing ‘..’ and entering twice.

3. Set the WAN and get information (When setting Fixed IP Address of RSG IP Address) 1) At ‘main:>’, type ‘wan’ and confirm to display the help menu. 2) At ‘main:/wan’, type ‘wanset’ and it displays the help menu and the current value of mode. 3) As the help menu says, input the value of IP address, Gateway address and Subnet Mask. Ex) main:/wan/wanset> set ip xxx.xxx.xxx.xxx Ex) main:/wan/wanset> set gateway xxx.xxx.xxx.xxx Ex) main:/wan/wanset> set subnet xxx.xxx.xxx.xxx 4) If you want to verify the changed value, please type ‘get all’. 5) The mode of wan has to be FIXED. Verify the mode by typing ‘mode’ or ‘get all’. Ex) main:/wan/wanset> get all

RSG Setting Procedure on RSG(ADSL PPPoE) 4. Set the PPPoE and get information (When setting Dynamic IP address) 1) Change the mode of WAN from FIXED into DYNAMIC by typing ‘mode’ at ‘main:/wan/wanset’. Ex) main:/wan/wanset> mode 2) Change the mode of PPPoE from INACTIVE into ACTIVE by typing ‘mode’ at ‘main:/wan/pppoe’. Ex) main:/wan/pppoe> mode 3) As the help menu says, type the value of ID and password.
