TRAI releases “The Telecommunication Interconnection (Port Charges) (Third Amendment) Regulations, 2026”

1. At a Glance

• What it is: a TRAI amendment that adds a charging framework for IP-based interconnection ports to the port-charge regime, effective 1 January 2027 [1].
• Core change: the definition of "Port" now covers legacy E1 ports (2.048 Mbps) and IP ports (bandwidth in Mbps or Gbps), with annual ceilings of ₹5.6 lakh (1 Gbps) and ₹42.3 lakh (10 Gbps) [1].
• Why it matters: it is a compact case study of ex-ante price regulation, a statutory regulator's consultative rule-making, and regulation adapting to technology change [1].

2. Why in the News

• TRAI released the Port Charges (Third Amendment) Regulations, 2026, replacing sole reliance on E1/TDM-based charges last revised in 2012 [1].
• A separately titled instrument, the Telecommunication Interconnection (Third Amendment) Regulations, 2026, was released on 3 November 2026. It also takes effect on 1 January 2027 and governs IP migration [2].
• The digest does not state the release date of the Port Charges amendment, so verify it on the PIB page before quoting one [1].

3. Background & Evolution

• 1997: the TRAI Act (Act No. 24 of 1997) was enacted; Section 11 sets out the "Functions of Authority" [5].
• 2000: Section 11(1)(b)(iv), in its form as amended in 2000, covers regulating revenue-sharing arrangements among service providers [6].
• 2001: the Telecommunication Interconnection (Port Charges) Regulation prescribed the charges for terminating interconnection links [1].
• 2012: E1 port charges were last revised [1].
• February 2015 (related regime): TRAI set zero mobile termination charges for wireline-originated calls and zero fixed termination charges for calls from either network, aiming to support wireline investment for high-speed internet [9].
• 2018: the Telecommunication Interconnection Regulations were issued, among the nine interconnection regulations later reviewed [3].
• 2023: the Telecommunications Act amended the TRAI Act, including its qualification provisions for the TDSAT chairperson and members, as described in PRS's analysis of the Bill [7][8].
• 3 April 2025: TRAI issued the Pre-Consultation Paper seeking early comments [1].

Key definitions

• Interconnection: the technical, operational and commercial arrangements connecting two or more networks, so that users of different service providers can communicate [1].
• Port charges: charges paid by the seeker to the provider for terminating interconnection links at the point of interconnection [1].
• TDM: Time Division Multiplexing, the legacy technology underlying E1 ports [1].

5. Multi-Dimensional Analysis

Economic

• Ceilings limit what a provider can charge, which restrains the use of port pricing against an interconnecting rival [1].
• Derived from S1: the 10 Gbps ceiling works out to ₹4.23 lakh per Gbps against ₹5.6 lakh at 1 Gbps, about 24% lower per Gbps, so the ceilings favour larger ports [1].
• Inference: predictable ceilings lower uncertainty in capacity planning, consistent with TRAI's stated aim of regulatory certainty [1].

Scientific / Technological

• Derived from S1: 1 Gbps is roughly 488 times the raw capacity of one 2.048 Mbps E1 port, which shows why E1-denominated pricing fits IP capacity poorly [1].
• Pricing is expressed in bandwidth terms, matching the companion mandate that all new interconnections be IP-based [1][2].
• TRAI cites better bandwidth efficiency and call quality as the reason for IP migration [2].

Legal / Constitutional

• The power flows from Section 11(1)(b) of the TRAI Act, making this delegated, statutory price-setting [1].
• Section 13 separately allows TRAI to issue directions to service providers for discharging its Section 11(1) functions [5].
• TDSAT, established under the TRAI Act, hears appeals against TRAI's directions and adjudicates certain disputes [7][8].
• Whether the Telecommunications Act, 2023 changes Section 11 or interconnection powers could not be confirmed from the sources retrieved; check the enacted text [10].

Ethical / Governance

• The process had several stages: pre-consultation paper, consultation paper, written comments and counter-comments, and an Open House Discussion [1].
• The companion regulation records 17 comments and 9 counter-comments [2].
• Requiring the same methodology for non-standard capacities limits discretionary or opaque pricing [1].

Administrative

• Enforcement is graded to the contravention and capped per Service Area for each instance [1].
• E1 and IP charging will coexist, because existing E1/TDM points of interconnection have three years to migrate in phases [1][2].
• Reporting requirements under the companion regulation allow TRAI to monitor the E1/TDM-to-IP migration [2].

6. Recent Developments (last 12-18 months)

• 10 November 2025: TRAI released the Consultation Paper "Review of existing TRAI Regulations on Interconnection matters", covering nine regulations, including the Port Charges Regulations, 2001 [1][3].
• December 2025: deadlines were extended to 15 December 2025 for comments and 29 December 2025 for counter-comments [4].
• 28 January 2026: Open House Discussion, as recorded for the companion regulation [2].
• 3 November 2026: the Telecommunication Interconnection (Third Amendment) Regulations, 2026 were released [2].
• 2026: the Port Charges (Third Amendment) Regulations were released [1].
• 1 January 2027: both instruments take effect [1][2].

• Capacity of an E1 port: 2.048 Mbps [1].
• Annual ceiling for a 1 Gbps IP port: ₹5.6 lakh [1].
• Annual ceiling for a 10 Gbps IP port: ₹42.3 lakh [1].
• Parties may agree on charges below the ceiling [1].
• IP-port charges apply equally to fixed-line, mobile, NLD and ILD services [1].

• Enabling provision: Section 11(1)(b), TRAI Act, 1997 [1].
• Pre-Consultation Paper: 3 April 2025; Consultation Paper: 10 November 2025 [1].
• All new interconnections after the companion regulation comes into force must be IP-based [2].
• Existing E1/TDM points of interconnection must move to IP within three years, in phases [2].
• TDSAT is established under the TRAI Act, 1997 [7][8].

8. Why the Ceiling May Become the Actual Price

• The seller has little reason to charge less than the maximum
• ₹5.6 lakh and ₹42.3 lakh are maximums, and the parties may agree on less [1].
• But the interconnection seeker (the operator asking to connect) must connect to reach the other network's customers. It cannot walk away.

• Inference: a provider facing a rival that has no other option has little reason to offer a discount. So the "maximum" may work as the normal price.

• The sizes between 1 Gbps and 10 Gbps have no rupee limit

• Only two sizes have a fixed ceiling. All other capacities are left to mutual agreement, using the same methodology [1].
• The rule works only if the seeker can check the sum. The note's account of the release gives the ceilings, but not the cost inputs behind them [1].
• If the two sides disagree, the likely route is TDSAT (Telecom Disputes Settlement and Appellate Tribunal), which hears disputes between service providers [7][8]. That costs time, and a new entrant has little time to spare.

9. Why Small Operators Pay More for Each Gbps

• The ceilings reward the operator that buys big
• Ten separate 1 Gbps ports could cost up to ₹56 lakh a year. One 10 Gbps port costs at most ₹42.3 lakh [1].
• So the same total capacity can cost about 32% more when bought in small pieces (calculated from S1).

• An operator with little traffic cannot use a 10 Gbps port fully, so it stays on the costlier rate per Gbps.

• This is not automatically unfair

• Inference: a bigger port may really cost less per Gbps to provide. If so, the lower rate only reflects cost.

• Without the cost data, a student cannot say whether the gap reflects cost or favours the large operators.

• The same ceiling applies to a dominant seller and a small one

• Nothing in the note's account sets a lower ceiling for a dominant operator [1].
• TRAI's older interconnection rules already defined Significant Market Power (a provider with at least 30% of activity in a service area) [14]. Check whether this definition still applies today.
• One ceiling for everyone is not unusual. Brazil's ex-ante interconnection rates (rates fixed by the regulator in advance) have been the same for all operators since 2018 [16].

10. Why Set a Price Ceiling When the Internet Runs on Private Deals?

• The strongest objection
• Internet networks mostly exchange traffic through commercial deals. Peering (two networks carrying each other's traffic without payment) is generally not regulated [15].
• So a critic can ask why IP ports in telecom need a government price limit at all.

• The critic has a second point. A price fixed in rupees grows old quickly: E1 charges went unrevised from 2012 until this amendment [1].

• The answer

• Inference: on the Internet, traffic can often take another route through another network. A phone call to a customer of one operator can end only on that operator's network.
• The companion regulation requires all new interconnections to be IP-based [2]. So the seeker cannot choose the old technology to avoid an IP price.

• The ceiling still leaves room for commercial deals, because parties can agree on a lower price [1].

• What the critic gets right

• A ceiling protects the seeker only while it stays close to real cost.
• A ceiling that is rarely revised can end up protecting the seller's margin instead. The case for a ceiling is strong, but the case for leaving it unrevised for years is weak.

11. Why the ₹15 Lakh Penalty May Not Scare a Big Operator

• The penalty is small next to the charge on a large port
• The ceiling on the financial disincentive is ₹15 lakh per Service Area per contravention [1].
• That is about 2.7 times the yearly ceiling for a 1 Gbps port, but only about 35% of the yearly ceiling for a 10 Gbps port (calculated from S1).
• Inference: the real gain from delaying a rival is not the port fee. It is keeping customers who would otherwise find the rival's service poor. A fixed cap does not grow with that gain.

• In fairness, the cap applies to each contravention in each Service Area, so repeated breaches can add up [1].

• A penalty works only when it is actually collected

• CAG (Comptroller and Auditor General) audited the TERM Cells of the Department of Telecommunications. It found that imposing a penalty without recovering it "defeated the purpose" of the penalty [13].
• That finding concerns the Department of Telecommunications, not TRAI. But it warns what to look for here: the amount collected, not the amount announced.

12. The Port Fee Is Only One Part of the Bill

• The companion regulation brings other costs at the same time
• Traffic at LDCA/SDCA-level points of interconnection (local charging areas) must move to LSA-level points (the whole Licensed Service Area) within three years, in phases [2].
• The method for setting the ceiling on bank guarantees (money or credit an operator keeps as security) has been revised, including for IP-based points [2].
• Interest on late payment is capped at SBI's one-year MCLR (its benchmark lending rate) plus 2% [2].

• So an operator's real cost depends on all of these together. Reading only the ₹5.6 lakh figure gives half the picture.

• Moving to fewer, larger points may suit large operators better

• Inference: LSA-level interconnection gathers traffic at a higher level, which pushes operators towards bigger ports. Bigger ports have the lower rate per Gbps [1][2].

• Billing can break even when the price is clear

• BSNL signed agreements with Airtel, Idea and Vodafone on SMS termination charges without a technical arrangement for billing them [12].
• Airtel and Vodafone then appealed to TDSAT [12].

• Ports moving from E1 to IP during the three-year period, with two price systems running together, will need similar care [1][2].

• What nobody has measured yet

• The sources found give no estimate of what the E1/TDM-to-IP move will cost operators.
• No CAG or parliamentary committee assessment of this amendment was found. It has not yet taken effect, so treat claims about its impact with care.

13. What TRAI Should Fix Before These Ceilings Get Old

• TRAI should fix a review date for the ceilings
• E1 charges went at least 14 years without revision, from 2012 to this amendment [1].
• The note reports no review date for the new IP ceilings [1].

• A set review cycle, with the cost inputs published, would let operators check whether the ceilings still match cost.

• TRAI should publish a ready price table for other port sizes

• Today only 1 Gbps and 10 Gbps have rupee limits [1].

• Worked figures from the same methodology would give a small operator a number to quote, and reduce the need to go to TDSAT.

• TRAI should publish penalties imposed and penalties collected, every year

• CAG's finding on penalties that were imposed but not recovered shows why the second number matters [13].

• Operators should write billing arrangements into agreements before 1 January 2027

• The agreements should say how a port that moves from E1 to IP in mid-year is billed and reconciled.

• The BSNL SMS case shows the cost of signing first and arranging billing later [12].

• TRAI should publish migration progress by operator and phase

• Operators already have to report on the E1/TDM-to-IP move [2].
• Public figures would show early whether any operator is falling behind, well before the three years end.

14. Anchors for Answers

• Data: 10 Gbps ceiling works out to ₹4.23 lakh per Gbps against ₹5.6 lakh at 1 Gbps, so the same capacity bought in small ports can cost about 32% more [1]
• Data: the ₹15 lakh penalty cap is about 35% of one year's ceiling on a 10 Gbps port [1]
• Report/Committee: CAG audit of DoT's TERM Cells: a penalty imposed but not recovered "defeated the purpose" [13]
• Report/Committee: CAG Report No. 29 of 2016: BSNL signed SMS interconnection agreements without a billing arrangement, leading to appeals at TDSAT [12]
• Law/Case: Section 11(1)(b), TRAI Act, 1997: power to set interconnection terms [1]; TDSAT hears appeals and disputes between service providers [7][8]
• Comparison: Brazil: ex-ante interconnection rates have been the same for all operators since 2018, and its voice model is technology-neutral except for calls that start on the Internet [16]
• Comparison: Internet peering is generally left to commercial deals, unlike India's price ceilings on IP ports [15]

15. Mains Relevance

• GS-II: Statutory, regulatory and various quasi-judicial bodies.
• GS-III: Infrastructure; Awareness in the field of IT; Government policies for sectoral development.

Plausible question stems

1. "Regulation must evolve with technology." Examine this in the context of TRAI's framework for IP-based interconnection.
2. Discuss the rationale for ceiling-based, rather than fixed, pricing of telecom interconnection. How does it balance competition and investment?
3. Critically evaluate TRAI's consultative rule-making as a model of transparency and accountability among India's sectoral regulators.

18. Common Errors / Trap Areas

• Two "Third Amendments": the Port Charges amendment sets charges, while the Telecommunication Interconnection amendment governs IP migration [1][2].
• Ceiling vs tariff: ₹5.6 lakh and ₹42.3 lakh are maximums, not fixed prices [1].
• Who pays: the seeker pays; the provider receives the link at its point of interconnection [1].
• E1 not abolished by this amendment: earlier charges continue, but only for E1 ports [1].
• Regulation date vs effective date: the amendment is dated 2026 but takes effect on 1 January 2027 [1].
• Per-unit scaling: 10 Gbps is not 10 × ₹5.6 lakh [1].
