Buying Tips
A wide range of calling features and reliability up to the five 9 levels are
a must for public telephone services. Needless to say, the switch has to
carrier-grade, engineered to operate under heavy traffic loads and harsh
conditions. It will be better to check if the equipment is tested and already
operating with live customers.
n Capability
and Manageability: Since switching is a long-term investment, operators want
to put in their money on a long-term basis. And price is a function of such
factors as per line cost of equipment, the services that can be operated by the
equipment, interoperability, scalability, ease-of-operation and manageability.
n Beyond the
Cost: True, the cost of the equipment is a critical factor in equipment
procurement. However, if the purchased equipment requires a long installation
period and/or if technical support is not available onsite, the benefits of the
new equipment are not realized. Thus, it is very important to work with a vendor
with a proven track record for timely and customized technical support.
n State-of-the-art
Technologies: India having very low teledensity, there is a huge opportunity
to adapt new technology, as legacy infrastructure is still low. Operators should
look for the latest technology in the market which is able to evolve to the next
generation networks without much investment in opex and capex. This helps the
operator to offer new services.
n Multi-service
Capability: Switch should be multi-service and capable for multiple network
application simultaneously (local, transit, mobile). Ensure that the switch is
based on an open architecture that eliminates dependence on suppliers for new
products and services.
