Hello Janardan,
it's a peaty, but i do not know alcatel infrastructure, so i can not provide you information about how to integrate it with cisco gateway or directly to sap BCM if it is possible.
An image provides an example of pbx and bcm integration:
______________________________________
Try to ask your IT/Network specialists how to route sip from alcatel to cisco gateway.
To install BCM system you need some servers, or virtual machines (on VMware for instance).
According to the SAP Contact Centre Introductory Training Installation Examplele try to install it.
