Administration and Provisioning
8-122 Issue 8.0 July 2002
— The Primary DS1 In/Out Format parameter specifies whether the
TIMING IN PRI and TIMING OUT 1 DS1 reference signals use
superframe (SF) or extended superframe (ESF) format.
— The Secondary DS1 In Format parameter specifies whether the
secondary DS1 reference signal uses superframe (SF) or extended
superframe (ESF) format.
— The Secondary DS1 In/Out Format parameter specifies whether the
TIMING IN SEC and TIMING OUT 2 DS1 reference signals use
superframe (SF) or extended superframe (ESF) format.
— The Primary DS1 In Line Code parameter specifies whether the
primary DS1 reference signal uses alternate mark inversion (AMI) or
bipolar eight zero substitution (B8ZS) line coding.
— The Secondary DS1 In Line Code parameter specifies whether the
secondary DS1 reference signal uses alternate mark inversion
(AMI) or bipolar eight zero substitution (B8ZS) line coding.
— The Synchronization Source parameter specifies that timing is
derived from the East or West high-speed lines or that timing is
automatically chosen depending upon which line provides the best
timing source.
— The DS1 Out 1 Equalization parameter provisions the DS1 Out 1 to
drive "20, 40, 60, 80, or 100" percent of its maximum rated cable
length. The cable lengths are based on YR28365 cable. Provision
the equalization to the smallest value greater than the actual cable
length based on the following:
Optimum Equalization
Setting (Percent)
Cable Length to
DSX-1 Panel (Feet)
20 0 - 133
40 133 - 267
60 267 - 400
80 400 - 533
100 533 - 655
