From the ISDN Channel Setup menu type a letter (A through E) and press <Enter> to choose a
setup parameter. Select one of the two options available for each parameter (Table 5):
The options in Table 5 listed in bold type are the default settings
Table 5. ISDN Channel Unit Configuration Options
Parameter
Description
Options
A)
PM Mode
Performance monitoring of the ISDN
channels is done considering the
channel as one path (Interim Path) or
several separate sections (Segmented).
Interim
Performance monitoring is done
considering the channel as one path
and collects the end-to-end error rate
for the entire transport path.
Segmented Performance monitoring is done
considering the channel as separate
sections, and collects error rates for
each DSL loop individually
B)
eoc mode
This parameter determines how ISDN
eoc messages are handled by the
PG-Flex system.
Normal
ISDN eoc messages are decoded and
re-transmitted within the PG-Flex
system.
Transparent ISDN eoc messages are not decoded
and are passed through the PG-Flex
system transparently.
C)
B1<->B2 Swap
This parameter determines whether
the B channels are swapped between
the PG-Flex CO ISDN “U” interface
and the RT ISDN “U” interface. The
“D” signaling channel is unaffected by
this parameter.
Normal
ISDN channel “B1” and “B2” at the
CO ISDN “U” interface are routed
to channels “B1” and “B2” at the RT
ISDN “U” interface.
Swap
ISDN channel “B1” and “B2” at the
CO ISDN “U” interface are routed
to channels “B2” and “B1” at the RT
ISDN “U” interface.
D)
Sealing Current
This parameter determines whether
sealing current is applied to the ISDN
subscriber loop.
Off
No sealing current is applied to the
ISDN subscriber loop.
On
A constant current of approximately
5 ma. flowing in the ISDN
subscriber loop at all times.
E)
Zero Byte
Substitution
This parameter determines how ISDN
eoc messages are handled by the
PG-Flex system.
Off
The PG-Flex system passes all data
through without any special
encoding.
On
The PG-Flex system will use a ZBS
code to prevent long string of zeros
in the data.

From the ISDN Channel Setup menu type <S> and press <Enter> to select a new ISDN channel
unit and channel to configure.
Type the channel unit number followed by a comma, then type the channel for the new ISDN
channel unit. That is, type “2, 3” for ISDN card number 2 on channel 3.
