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 which 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.
Bit Rate
This field is used to select domestic T1 operation or international E1 operation for
all facilities in the TN1654 DS1 CONV Complex. The field is set to
1.544
Mbps for
T1 operation and
2.048
Mbps for E1 operation.
This field appears on the fiber-link form only for TN1654 DS1 CONV circuit packs.
NOTE:
The TN1654 DS1 CONV circuit pack is also field configurable for T1 or E1
operation. All four DS1 facilities are configured to either T1 or E1 as a group
via an option switch located on the component side of the circuit pack. An
error will be logged and an alarm will be raised if there is a T1/E1
inconsistency between the administered bit rate and the board option
switch setting.
Idle Code
This field is used to set the idle code for all facilities on the TN1654 DS1 CONV
board. This field can accept any combination of ones (1) and zeros (0) with the
exception that the second left-most digit must be set to one (1) at all times.
This field appears on the fiber-link form only for TN1654 DS1 CONV circuit packs.
