Type
Letter Parameter Default Value Function
A PM Mode Interim Path Performance monitoring of the ISDN channels is done considering the
channel as one path (Interim Path) or several separate sections
(Segmented), according to the setting of this parameter. The default
setting is Interim Path. Interim Path performance monitoring collects
end-to-end error rate for the entire transport path. Segmented
monitoring collects error rates for each DSL loop individually.
B eoc Mode Normal With the “Normal” setting, ISDN eoc messages are decoded and re-
transmitted within the PG-Flex system. In the “transparent” mode,
ISDN eoc messages are not decoded and are passed through the system
transparently. The default setting is “Normal.”
C B1 <-> B2
swap Normal With the “Swap” setting, ISDN channel “B1” and “B2” at the CO ISDN
“U” interface are routed to channels “B2” and “B1” at the RT ISDN “U”
interface. The “D” signaling channel is unaffected. The default is
“Normal.”
D Sealing current Off When Sealing Current is set to “On,” there is a constant current of
approximately 5 ma. flowing in the ISDN subscriber loop at all times.
The default setting is “Off” (no sealing current).
E Zero Byte
Substitution Off When this parameter is set to ENABLED, the PG-Flex system uses a
ZBS code to prevent long string of zeros in the data. This is not required
for proper operation of the PG-Flex system and this parameter is
normally left at “Off.” The default setting is “Off.”
