compliance with the requirements of paragraphs (a) and (c) of this 
section; and
    (2) Withhold payment (on a location-by-location basis) of any

involving equal access codes, shall, within six (6) months of the 
effective date of this paragraph or upon installation, whichever is 
sooner, allow the consumer to use equal access codes to obtain access to 
the consumer's desired provider of operator services.

capable of blocking access through such dialing sequences without 
blocking access through other dialing sequences involving equal access 
codes, shall, within eighteen (18) months of the effective date of this 
paragraph, allow the consumer to use equal access codes to obtain access 
to the consumer's desired provider of operator services.
    (5) All equipment not included in paragraphs (c)(1), (c)(2), (c)(3),
