System
Line Buildout T1 line buildout is configurable to 0 dB, –7.5 dB, or
–15 dB, as required by FCC Part 68. Buildout sets the
SLC ConnectReach system's output T1 transmission
signal level (0 dB is the highest level and -15 dB is the
lowest level). The default, 0 dB, is the most common
signal level for connection to the carrier. If line buildout
is set incorrectly, the carrier may detect errors ranging
from bipolar violations (line buildout too high) to loss of
signal (line buildout too low).
Pulse Density
Enforcement This option is used when AMI line coding is selected
(see the description of line coding presented earlier).
Per the AT&T TR-62411 ACCUNET specification, bit
stuffing must be enabled when AMI line coding is
selected. This ensures that ones density requirements
are met (see ANSI standard T1.403, paragraph 5.6).
Alarm Operation This option controls whether the secondary/fractional
T1/DSX-1 going down causes the alarm relay to close.
Refer to Chapter 9, "Software Upgrade, Maintenance,
and Trouble Clearing", for more information.
Alarm Delay This option sets the delay between the
secondary/fractional T1/DSX-1 alarm and the closing
of the alarm relay.
Has Slave This option allows the SLC ConnectReach system to
serve as the master unit in a 48-line master/slave
configuration. Refer to Chapter 5, "Installation" for
details on the 48-line master/slave configuration.
NOTE:
The clock source for the secondary/fractional T1/DSX-1 is always internal,
synchronous to the network T1/DSX-1.
