                    technology and the latest advanced components available now
                    a days enable OEM vendor to develop dense cards which are
                    much smaller in size and provides multiple functionality. This
                    provides more scalability to the service providers rather than
                    restricting them and this is now a day’s demand of each Service

                    as OEM's product and the requirement of experience of STM16
                    MSPP, STM16 and STM64 are only allowed which will restrict

                    We request you to kindly allow the experience of STM-1 and STM-4
                    also since these are parts of SDH series equipments and BSNL was
                    also previously considering the same in various tenders for allowing of
