y when the facility is installed.
For TN574 DS1 converter boards, facility A must be installed first. Install
Facilities B, C and D in any order on any of the four facilities.
For TN1654 DS1 converter boards, facility A must be installed first, then B,
then C or D. This is required because the primary facility can only reside on
facilities A or B.
y when the DS1 facility is used as a clock reference for the receive fiber
signal.
Appears on the Fiber-Link screen for TN574 DS1 converter circuit packs.
On the TN1654 DS1 converter board, none of the facilities can be used as a
clock reference for the receive fiber signal, and administration of this field is
not applicable.
DS1 facilities cot be used as system synchronization sources.
y when the DS1 facility is digital data compatible and suitable for carrying
packet traffic.
Appears on the Fiber-link screen for TN574 DS1 converter 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 converter board allows packet traffic only on facilities A
and B, and administration of this field is not applicable.
Bit Rate Select domestic T1 operation or international E1 operation for all facilities in
the TN1654 DS1 converter complex:
● 1.544 Mbps for T1 operation
● 2.048 Mbps for E1 operation
Appears on the fiber-link screen only for TN1654 DS1 converter circuit
packs.
The TN1654 DS1 converter 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 is logged and an alarm is raised if there is a T1/E1 inconsistency
between the administered bit rate and the board option switch setting.
