Close on the heels of the revising tariffs for domestic bandwidth, telecom regularor Trai today announced ceiling tariff for managed leased line network (MLLN).The authority has for the first time made a distinction between leased circuits of the classical kind and leased circuit that are provided through MLLN technology.The tariff ceiling for 64 kbps domestic leased circuits of the classical kind for distance over 500 km is Rs 44,000 while it is Rs 7,000 more at Rs 51,000 for MLLN.In addition to 64 kbps, distance-based tariff ceilings have been specified for capacities of 128 kbps and 256 kbps while for capacities more than 256 kbps and below 2mbps, tariff has been kept under forbearance due to low and specialised demand for these capacities, a Trai release said.Although the price of the modem has been kept under forbearance, the authority has specified that these modems must be provided on rental, with tariff for such equipment based on cost and reasonable recovery period, Trai said. Trai said it would review the ceiling tariff after a year based on the prevailing market trends and other relevant factors at that time.The authority said that in specifying the higher tariff ceiling for MLLN provided leased circuits, it examined the additional costs associated with providing the value-added features with service.In keeping with the approach of specifying ceiling traiff for traditional leased circuits, tariffs for MLLN have also been specified based on capacity and distance, the release added.
