Analogue Phone Adapter
The LT-4200 system is supporting connection of one or more external Analogue Phone Adapters (e.g.
Grandstream). Each of the
POTS’ phones (Plain Old Telephone System)
connected to the Analogue Phone
Adapter, must be configured as individual SIP phones in the LT-4200 system, see configuration of SIP
phones in
on page 95. Connect the SIP phones directly to the LT-4210 Control Unit
Ethernet (LAN port).
NOTE
:
The Analogue Phone Adapter might require a DHCP Server to get an IP address assigned.
Depending on network setup, it might be needed to configure DHCP Server mode in the LT-
4200 system.
To provide some guidance for configuration of an Analogue Phone Adapter, the following description will
outline some important steps for configuring an Analogue Phone Adapter.
Configuration of Grandstream HT802 Adapter (example):
If you would like to connect the Analogue Phone Adapter directly to the LT-4200 system, then it might help
you to insert a passive switch between the LT-4200 system and the Analogue Phone Adapter, while
completing the setup (to allow for an extra LAN port during configuration).
Step 1: Connect the LT-4200 system, Analogue Phone Adapter, and PC using a passive switch
Step 2: Login to the LT-4200 system web server. The IP address can be read from the display (MENU ->
System -> Network: IP address)
Step 3: Configure the LT-4200
system to ‘DHCP Server’ mode (depending on network setup) and configure
the SIP phones (Password, and Caller ID)
Step 4: The Analogue Phone Adapter will now have an IP address assigned. Connect a POTS phone to the
Analogue Phone Adapter and use the IVR menu to read out the IP address (off hook handset and
type ‘***’ followed by ‘02’). Check the instructio
ns provided for the Analogue Phone Adapter
Step 5: Log in to the Analogue Phone Adapter and configure FXS PORT 1 and PORT 2 (Primary SIP Server,
SIP User ID, Authenticate ID, Password, and Name)
Step 6: The POTS phones should now be registered and ready to use (the passive switch can be removed).
