Table 533-1. RLXIOR Configuration Fields, continued
OPTIONS
Leave this field at OOS at this time to avoid undesirable reporting of alarms. Set this field to IS
after completing the configuration of the remaining fields.
YES Brings up T1 default settings and allows
configuration changes.
NO No configuration changes allowed.
Leave this field at OOS at this time to avoid undesirable reporting of alarms. Set this field to IS
after completing the configuration of the remaining fields, and after configuring the Unit Service
State field.
AUTO When the RLX line code is set to AUTO,
the module senses the line code and
switches from AMI to B8ZS if an encoded
signal is detected. After switching to
B8ZS, the RLX stays locked in this line
code until an LOS is detected at both DS1
inputs.
AMI Alternate Mark Inversion
B8ZS Bipolar Eight-Zero Substitution
AUTO The system automatically detects,
establishes, and displays "AUTO-NR-"
and the correct frame format
(UNFRAMED, FT ONLY, SF, or ESF).
UNFRAMED Unframed data pattern
Ft ONLY Used for SLC framing
SF Super Frame
ESF Extended Super Frame
NRZ This tells the Craft that the network DS1
source is at the backplane.
BIPOLAR This tells the Craft that the network DS1
source is at the extender card interface. If
this option is selected and there is no
extender card, the DS1 signal is cut off. In
the Loop Extender chassis, this field is
locked at BIPOLAR.
Range of 10 -3 to 10 -9
The average Bit Error Ratios of both the
incoming DS1 signals are monitored by
the RLX. By monitoring BERs, the RLX
is capable of triggering a minor alarm
when any of the monitored signals
degrades below the BER threshold level.
