However, this does not preclude the possibility of earlier provisioning of the
Interconnect capacity in full or in part subject to technical feasibility and
availability.
18
However, Interconnection with a capacity upto 2 E1 ports (1 E1 port in case
of SDCC Tandem switch wherever there is capacity constraint) as
ascertained by the MTNL, required for the launch of the service for the first
time in the service area, shall normally, be provided within
90 days of
payment of the demand note, unless found to be technically non feasible and
subject to conditions as mentioned above.
3.1.3 On the acceptance of the demand, in full or part, the interconnection provider
shall issue Demand Notes (Bill) within 30 days of the formal demand, for the
capacity to be provided. The seeker shall then make the payment within 30
days of receiving such Demand Note (Bill). The date of payment shall be
taken as date of firm demand. Any change in the firm demand shall be
intimated within 15 days of making the payment, after which no changes will
be allowed.
3.1.4 The balance requested capacity of ports not likely to be met within 6 months,
shall be treated as firm demand if the Party B wishes so and makes the
payment of demand note. Planning for requirement against this demand will
start only after payment of the demand note. The capacity will be provided in
a mutually agreed time frame.
3.1.5 As stated in clause B.1.1 and 5B.1.1, UASP is responsible for providing the
required transmission links to and from MTNL’s network at permitted interface
points at TANDEMS / LOCAL EXCHANGE levels initially as well as for

considered by the Coordination Committee for further necessary action under
this agreement.
3.3.3 Number of Ports, for which demand notes have been issued by MTNL and
paid by Party B for each POI on each occasion, will be the deciding factor for
determining the port charges in terms of the Regulations.
3.3.4 The party installing the equipment and requiring inter-connectivity tests shall,
notify to the other party indicating that such capacity is ready for testing as
per mutually agreed Test Schedules. The proforma for such notification and

ANNEXURE B
Charging Principles for Infrastructure Sharing
In case of any infrastructure, sharing between any two operators, following
things are necessarily required to be provided by the operator who is providing &
sharing its facilities. These include provision of infrastructure support for carrying
the cables in the building, transmission room, termination of cable runways, space
for system installation in the room, DC & AC power from two sources ( Main +
Standby ), Engine alternators, supply ( Main + Standby ), air conditioning, security
of the equipment, operation and maintenance of the entire infrastructure etc.
2.
For provision of power (DC & AC) the minimum possible configuration rating
equipment which are required to be established for a telecom transmission
centre set up will be taken into consideration for costing purpose. Though in
the establishment of a telecom infrastructure of any operator, the increments
in DC power supply are of the order of 100/200 ampere modules, engine
alternator capacity increase is done normally in an increment of 100 KVAs, air
conditioning of the total room is done is much higher than the slabs of two
tons. For charging these facilities, costs will be worked out based on a small
set up required to be established for a Transmission Centre at any location on
a stand alone basis. A&P items will be taken for a small capacity i.e.
electrical installations & fittings, two A/Cs of 2 Tons only, 25 KVA E/A (Main +
Standby), Fire Detection System, Fire Fighting System, power plant of 50
Amp. (Main + Standby) AC power (Main + Standby) etc.
3.
In regard to the land & building, the minimum size required to establish any
transmission centre with space and building will be taken into account. 20 sq.
mtr. built up area of the building and 40 sq. mtr. land will be taken for
accommodation of upto 5 Bays, although the existing telecom infrastructure
increments are done in hundreds of square meters If more than 5 bays are
required to be located by Party B, additional area at the rate of 20 sq.m 5
bays will be required to be taken by Party B. In the case of rented building,
sharing will not be permitted. The land & building cost will be taken as the
current rate of the development authority of that area or prevalent market
rates, whichever is higher.
4.
For carrying the cable in the building, the rates will be taken for a minimum 4
bore rate on average of Rs.1000/- per meter.
5.
Existing norms of MTNL for provision in P/Es for Maintenance / Installation
will be taken.
6.
The rates will be reviewed periodically on an annual basis .
7.
10% of the equipment cost will be taken as O & M charges if the equipment is
installed by Party ‘B’ itself.
8.
12% set up charges will be taken towards provision of facilities.
