(CATV) channels.
**************************************************************************
The system shall accommodate future expansion with minimum service
interruption.
a. The head end equipment shall be configured to allow adequate
rack space, power supplies, mixers, modulators, and combiners for
a minimum of twelve VHF channels.
b. The distribution equipment shall be configured as indicated.
Components in the distribution system shall, as a minimum, be
capable of distributing [12 VHF channels (2 - 6 low band VHF
including FM band and 7-13 high band VHF),] [35 CATV channels (2 -
W(36) low, mid, high and super band),].
1.4.2
System Performance
**************************************************************************
NOTE: The designer will prepare a listing of
off-air stations to be included in the installation,
with call letters, broadcast/cable channel, and
system distribution channel. The designer will
utilize the appropriate tables for the particular
system proposed. The tables numbered "Ia" and "Ib"
may be deleted and renumbered as required. The
results of the signal surveys conducted by the
designer will be included in TABLES Ia or Ib as they
apply. TABLES IIa and IIb reflect minimum system
performance requirements expected at each user
interface.
The exact number of FM stations and TV channels the
designer is specifying for the project is indicated
by the number of call letters and channels listed.
Reception and distribution of a TV channel or FM
station will not be attempted unless the antenna
height and antenna gain can be selected to deliver
at least a minus 10 dBmV signal to the amplifier.
Translation equipment will be provided to convert
VHF channel broadcast frequency to a suitable unused
VHF channel, in case of co-channel or adjacent
channel interference. Where UHF channels are
available, they will be converted to VHF or
non-broadcast channels available for distribution.
**************************************************************************
The system shall be capable of receiving broadcast signals from the
[television off-air] [and] [FM radio] stations designated below. The
designated stations named by call letters designated below are entered in
the "USE" column of TABLE I [a] [b] to indicate correspondence between the
channel on the cable distribution system and the received TV channels. The
system shall deliver to all user outlets the performance specified in
TABLES IIa and IIb.
a. Television Broadcast Stations. Programming received from the following
listed television stations shall be distributed on the cable distribution
system.
