Using Broadband Service
1. Connections & Installation
For extending the service, the telephone cable coming to the customer’s premises is connected to a ADSL2+
CPE using a POTS Splitter. The ADSL2+ CPE acts as an interface between the telephone cable and the
computer. The ‘POTS Splitter’ is used to separate voice and data signals enabling both Voice and Internet,
simultaneously, on the same telephone line. One cable out of the POTS Splitter is connected to the telephone
instrument. Your MTNL Broadband connection comes with a user account consisting of a Username and
Password. This is used by the CPE in establishing connection to the MTNL Broadband network. The username
and password are pre-configured in the MTNL ADSL2+ CPE. When the CPE is switched ‘ON’, it automatically
establishes a connection to the Broadband Network.
The ADSL2+ CPE and the POTS splitter shall be connected as per the figure given below-
