Reliance Jio on Thursday welcomed over 7,000 additional points of interconnect (PoIs) by Bharti Airtel, which took the total number of points to over 17,000.
However, Reliance said that over 4.6 crore calls are still failing everyday between the two operators' networks.
"This capacity is sufficient to serve over 75 million customers, based on the forecast provided by Jio to Airtel. This will also ensure that the quality of service (QoS) is maintained and the customers are not inconvenienced," an Airtel statement said.
"There are no network related issues that RJIL (Reliance Jio Infocomm Limited) has faced beyond the acute shortage of POIs provided by Airtel and other incumbent operators," said RJIL in a statement.
"It may be noted that there are no failures in on-net calls, while over 4.6 crore calls are still failing every day between Jio and Airtel," it added.
"Airtel has been providing PoIs to Jio, even before the commencement of Jio's commercial operations. Following the commercial launch of services by Jio on September 5, 2016, Airtel has released PoIs at a staggering pace, well ahead of its bilateral and regulatory obligations," Airtel said.
"As a matter of fact the number of PoIs provided by Airtel to Jio is more than 2.5 times the number provided to an existing operator with a comparable subscriber base," it added.
"RJIL hopes that this situation will improve now that Airtel has consented to offering additional POIs. However, Airtel has continued to violate the Interconnection Agreement by offering one-way E1s as against both-way E1s as provided for in the Agreement, which would have resulted in much more efficient utilisation of interconnection resources," RJIL said.
The Indian telecom regulator on October 21 slapped heavy penalties on three telecom players -- Bharti Airtel, Vodafone India and Idea Cellular -- for not providing sufficient PoIs to Reliance Jio.
It also said the action of the three operators showed "ulterior motive to stifle competition".
In three similar letters to the three players, the watchdog -- Telecom Regulatory Authority of India (TRAI) -- said it has recommended a penal action of Rs 50 crore per licence service area (LSA) except Jammu and Kashmir, where PoI congestion exceeded the allowable limit of 0.5 per cent as reported by Airtel/Vodafone/Idea Cellular through emails in September.
In the case of Airtel and Vodafone, the fines imposed were for 21 LSAs, amounting to Rs 1,050 crore each, while in the case of Idea, the fine was Rs 950 crore for 19 LSA.
"RJIL hopes that Airtel will continue to release adequate POIs going forward to ensure that it adheres to the QOS parameter of POI congestion mandated by TRAI regulation at less than 5 per 1,000 calls at all times," the telecom operator said.
"In June 2016, Jio had provided its forecast of projected points of interconnect to Airtel. At a meeting on November 1, 2016 in the presence of the TRAI, Jio reiterated its requirement and requested Airtel to provide sufficient PoIs in line with its forecast of June 2016," the Airtel statement said.
"With the latest augmentation, Airtel has now provided Jio the capacity to cater to 75 million customers. This is well ahead of the timeframe, since there are currently only 25 million customers making calls to the Airtel network fro" Jio," it added.
"Our regulatory obligations permit us to provide interconnect in a period of 90 days," the statement said.
With this augmentation Airtel said it has provided Jio capacity that is comparable to operators with six to eight times the customer base of Jio, in nine weeks of their lauch.
"We now request Jio to ensure that the additional POIs, that we have made available at a staggering pace, be operationalised with the same alacrity. This will help identify any network related issues, which Jio may have in their network should any problems persist, given the massive over capacities provided by us," Airtel said.
Jio has already provided Airtel their future requirements for capacities at 100 million customers.
"As and when they ramp up their current subscriber base, we will further augment capacities ahead of time, as we have always done," the statement said.
Airtel maintained that it was committed to comply with all TRAI regulations and Interconnect Agreements in lette.
They said that at the same time we request TRAI to examine the incredible asymmetry of calls terminating on the Airtel network from Jio due to free services being offered by Jio.
"This continued asymmetry will degrade the customer experience for Airtel customers over time and melt down networks," Airtel said.
With regard to the traffic asymmetry issue, the current traffic pattern is completely in line with what is expected in a new network, RJIL stated.
It would tend to move towards balanced traffic as the network matures and has sufficient scale, it added.
