10 working days.
Both parties agree on the generator upgrade specifications (see next
section 6.2.3 for further options and details)

Infrastructure seeker issues purchase order for site sharing,
infrastructure provider issues invoice, and infrastructure seeker gets site
access, as soon as invoice is paid.

6.2.3 As described in section 5.4.3 and sub-sections 5.4.3.1 and 5.4.3.2,
there are two basic options for the generator upgrade:
(1) the infrastructure provider arranges and pays for the generator
upgrade, in which case an additional monthly charge becomes
applicable (see section 5.4.3.1); or
(2) the infrastructure seeker will pay for the generator upgrade, in which
case either the Net Book Value of the existing generator will be
reimbursed by the infrastructure provider, or the existing generator
will be transferred to the infrastructure seeker (see section 5.4.3.2).
In all cases, the infrastructure provider will be responsible for operation and
maintenance of the generator.

Guidelines including the maximum prices will come into force.
6.3.2 For currently existing site-sharing agreements, there will be no retroactive adjustment of prices paid for sites shared before the effective date

6.3.3 If an existing site-sharing agreement covers a period beyond the
