Maintenance-Object Repair Procedures
DS1 Interface Options
The following DS1 Interface options must be set with fiber link administration. To
set the values, check the number of the fiber link via the list fibers command.
Execute the change fiber-link command and set the following fields:
Facility Installed
This field determines if the DS1 facility is installed. The field is set to yes if the
facility is installed.
For TN574 DS1 CONV boards, facility A must be installed before the others.
Facilities B, C and D can then be installed in any order desired since the primary
facility can reside on any of the four facilities.
For TN1654 DS1 CONV boards, facility A must be installed first, then B, then C or
D. This is required since the primary facility can only reside on facilities A or B.
Passes Far-End Clock
This field determines if the DS1 facility can be used as a clock reference for the
receive fiber signal. The field is set to yes unless the DS1 facility cannot be used
as clock reference signal.
This field appears on the fiber-link form only for TN574 DS1 CONV circuit packs.
On the TN1654 DS1 CONV board, none of the facilities can be used as a clock
reference for the receive fiber signal thus administration of this field is not
applicable.
DS1 facilities cannot be used as system synchronization sources.
Digital Data Compatible
This field determines if the DS1 facility is suitable for carrying packet traffic. The
field is set to yes unless the DS1 facility is not digital data compatible.
This field appears on the fiber-link form only for TN574 DS1 CONV circuit packs.
The TN574 circuit pack allows any of the four facilities to be used as the primary
facility that carries the packet traffic. The TN1654 DS1 CONV board, however,
allows packet traffic only on facilities A and B. Thus there is no need to administer
this information as it is already predetermined.
