Leased Circuit Tariff

B. Telephone Voice Circuits (Speech)

Point to Point & Single Party Network Mode Same Rate as prescribed for 64 Kbps high speed data circuits Local Lead to Telephone Voice Circuits (Speech) (i) Charge for leasing these local leads shall be the rate applicable to 64kbps High Speed data circuits as per para 1(A) above. The fraction of CD km will be rounded to next higher or (ii) If such leasing is not possible, then         (a) On rent and guarantee basis, or         (b) On contribution basis (iii) Maintenance of end link: Whenever the end link at subscribers premises is provided by the subscriber, the maintenance by MTNL shall be @ 10% of the cost of the link per annum.

C. Multiparty Network

Multiparty network is not permitted on Speech, Voice Band Data and High speed data circuits. It may be considered for Closed User Group or Broad User Group on case by case basis.

D. Ticker Connection

The Charge for Ticker Connection shall be same as that of a 50 Bauds Telegraph Circuits (Non-Press). Press do not enjoy any concessions as the Ticker Connections are exclusively provided for the Press.

E. Circuits in Telegraph Network

(On SFT/Message switching equipment/message concentrated etc.)  As for voice band data circuits as given above at (D) Additional Charges on SFT/Message switching equipment/message concentrator etc. for the Tele-printer networks (i) Up to an equipped capacity of 16 extensions Rs. 10,000 p.a. (ii) More than 16 extensions Rs. 10,000 + Rs. 5,000 p.a per additional extension or part thereof

F. Private Wires/Non Exchange Lines/Local Circuits  (for both voice and Data Transmission)

Same rate as applicable for 64 kbps High speed data circuits as per para 1(A) above. The fraction of CD km will be rounded to next higher.

G. Misc. Charges for Telegraph/Tele-printer/Telephone Circuits

(a) Reconnection Charges   (i) Within a period of 7 days from the date of     disconnection Rs. 30   (ii) In all other cases Rs. 60 (b)  Installation Charges   (i)Hand Micro Telephone Instrument Provided at either end Rs. 150 per instrument   (ii) Speech Circuits and T/P Circuits        Installation Charge Rs. 200 for each end        Shifting Charge Rs. 200 for each end (c) The tariff for interconnection between Public Data Network and Private Data Network through leased lines will be as under   Volume Charges Rs. 100 per kseg without any concession   Access Charges: For PSTN/Telex to Private Data Network PSTN TELEX     Rs. 15,000 p.a. per DEL Rs. 25,000 p.a. per Telex   License Fee for Network per annum (Nodal Charges) : NIL Managed Leased Line Network (MLLN) : The MLLN is a Managed Leased Line Network system which is proposed to provide Leased line connectivity.  With the State-of-the-art technology equipment, MLLN is designed mainly for having effective control and  monitor on the leased line so that the down time is very much minimised and the circuit efficiency is increased thus achieving more customer satisfaction.  This mainly deals with data circuits ranging from 64 KBPs to 2048 KBPs. In MLLN network conventional PCM primary MUX and subscriber Modems are replaced by versatile MUX and network terminating units respectively.  MLLN  mainly consists of Digital Cross Connect (DXC), versatile MUX (V MUX), Network Terminating Units (NTU) and Network Management System(NMS). DXC's and VMUX's are inter connected via optical fibre links with alternate routing facility in case of any route failure.  VMUX is in turn connected to NTU's placed at customer premises through 2 wire copper pair.  At the top of it NMS is suitably placed at the Central location for effective control& monitor.  NTUs are fully managed from NMS.  They are programmable for different data speeds ranging from 64 KBPs (n x64 KBPs:  nx1 to 32) depending upon the customer demand, thus having bandwidth control without changing Modem at his premises.  NTUs operate on 230 V AC.     Features of MLLN : Control, Manage the leased line network Bandwidth management as per the customer demand Pro-active maintenance, without waiting for customer to book  a complaint. Self Diagnostic/software loops to check E1 connectivity to DXC, VMUX/software loops for checking copper pair at NTU point for immediately identifying the faulty section for trouble shooting . Alternate routing in case of any route failure. Generation of the periodic performance reports for self-analysis/customer. Advantages to Customers : Bandwidth management as per customer requirement(64 Kbps and nx 64 Kbps  up to to 2048 Kbps ). Saving the cost of modems.  NTU is provided by MTNL without any charges. Proactive maintenance Tariff a)   NTU :   i)   Annual Charge - As applicable (see tariff for leased line less than 2 Mbps)  ii)   Security Deposit - NIL (w.e.f. 23.02.2008)
