How to Use a BSNL TERACOM-2 WIFI Modem as a WiFi Access Point (AP)

Hi everyone, This is my first post here.Recently i have purchased a TERACOM WiFi Modem (Model No: T2-B-Gawv1.4U10Y-BI) from BSNL it was configured by BSNL ppl and it is working fine. But what actually my requirement is to use this as a WiFi Access Point(AP) and not as a Wireless Router. Can anyone guide me in doing this?
