ds1ext
Syntax: ds1ext
ds1ext crc <CRCVAL> <LINE>
ds1ext linecode <LCVAL> <LINE>
ds1ext lbo <LBOVAL> <LINE>
Description: This command allows the user to modify various ds1
parameters that are extensions to RFC 1406. The
following is an explanation of the various command
options:
<LINE> - The MIB II ifIndex value used to represent a
DS1 interface.
<CRCVAL> - Amount of frame check sequence bits
appended to data. Valid values are 16 and 32.
<LCVAL> - Valid line code values are none, jBZS, and
invHDLC.
<LBOVAL> - Valid line build out values are 0, -7.5, -15,
133, 266, 399, and 533.
Options: ds1ext (with no options) displays currently programmed
parameters.
ds1ext crc <CRCVAL> <LINE> changes the amount of
frame check sequence bits appended to data transmitted
from the DS1 designated by <LINE> to <CRCVAL>.
ds1ext linecode <LCVAL> <LINE> changes the line
coding value programmed on the DS1 designated by
<LINE> to <LCVAL>. This value should not be modified
unless no other form of zero code suppression is used, and
the main line encoding does not provide zero code
suppression (as in AMI line coding).
ds1ext lbo <LBOVAL> changes the line build out value
programmed on the DS1 designated by <LINE> to
<LBOVAL>. The values 0, -7.5 and -15 are decibel levels
for long haul configurations, while the other values are
ranges, measured in feet for short haul configurations.
