INTERFACE #1: describes the Information Provider interface into the
Qwest Communications regulated BBPC network. This interface uses
the
Qwest DS1 Service transporting an Internet Protocol (IP)
connection at 1.544 Mbit/s. DS1 Service is a standard tariff service
offered by
Qwest Communications, Inc, available to customers and
carriers.
Procedures for ordering DS1 service can be found in Qwest
Service
Publication 77200, Issue D, October 1995.

INTERFACE #2: describes the interface at the network output to and
from the
subscriber's computer modem. This is a new interface that utilizes a 75
ohm
coaxial cable and a female F connector as the physical component. In
order to
meet Cumulative Leakage Index (CLI) requirements and end-to-end
specifications,
the inside wiring must be RG-6, dual shield, 60% aluminum polypropylene
braid
with the following loss requirements:
€ 6.5 dB at 100 feet at 750 MHz
€ 5.35 dB at 100 feet at 750 MHz
All inside wiring must meet the 1993 National Electrical Code, Article
820,
Section E requirements for Type CATV and CATVX available from the
National Fire
Protection Association (NFPA).

A 10 Mbit/s channel is derived on a 6 MHz RF envelope employing a
radio
frequency (RF) carrier modulation scheme of Quadrature Phase Shift Keying
(QPSK).
The 6 MHz RF envelope shall be assigned by Qwest
Communications
in the forward and reverse signal directions to complete the
communications link
for the customer. Interface #2 supports customer premises equipment (CPE)
for the
forward path QPSK electrical signal that is frequency agile between 54
MHz and
552 MHz. Interface #2 also supports CPE for the reverse path QPSK
electrical
signal that is frequency agile between 5 MHz and 42 MHz.
The minimum end-of-line signal requirements are as follows:
€ Carrier-to-Noise (for 1 in 109 BER) 22 dB
€ Carrier-to-Interference (for 1 in 109 BER) 25 dB
