Timing Provisioning
The Timing Provisioning menu items are used to
establish the clock mode and primary and secondary
timing source. The options include the following:
1. Clock Mode: Settings include Non-revertive or
Revertive clock mode. This decision should be
based on whether a primary and secondary timing
source are available. In the event that the primary
timing source is lost, the Total Access 1500 LIU
automatically switches to the secondary timing
source.
• Revertive: This setting allows the unit to revert to
the primary timing source if and when it becomes
available.
• Non-revertive: This setting allows the unit to
remain on the secondary timing source. If Non-
revertive is chosen and the secondary timing
source becomes active due to a primary timing
source failure and the secondary source fails, the
unit switches to the primary timing source if it has
become available.
2. Primary Timing Source: This option is used to
select the primary timing source for the T1s. The
settings include the following:
•Local
• Loop A
• Loop B
• Loop C
• Loop D
• Loop P

3. Secondary Timing Source:
This option is used to
select the secondary timing source for the T1s. The
settings include the following:
•Local
• Loop A
• Loop B
• Loop C
• Loop D
• Loop P
•CLK
This timing source becomes the current timing
source if the primary timing source is lost. If both
timing sources are lost, the timing reverts to local.
As timing sources are regained, the current timing
source reverts to the primary or secondary timing
source as they become available.

The threshold for each statistic can be indepen-
dently enabled, disabled, or have a specific value
entered. When enabled, and crossing of the thresh-
old value results in a threshold entry into the Total
Access 1500 Alarm Log. All thresholds are
defaulted to disabled.
4. ALARMS
The Total Access 1500 Quad LIU supports an external
clock input out-of-service alarm and can be enabled or
disabled. When the alarms are enabled, an alarm
condition is created when the external timing source is
lost.

The Test menu controls testing for the Total Access
1500 Quad LIU. The Test menu is used to select either
T1 A or B for testing, perform local and remote
loopbacks, select which T1 to monitor, and reset the
LIU. The loopbacks are described below.
Loopback Tests
The Quad LIU supports loopback tests to aid circuit
turnup and maintenance efforts. These tests are initiated
from the Total Access Site Manager or the Total Access
1500 local
ADMIN port on the SCU.
Local Loopback
T1 data is looped back toward the customer. The
transmit data is looped back after it has passed through
the framer and LIU circuitry.
Line and Local Loopback
The Quad LIU supports a bidirectional loopback via
menu access only. The loopback in the network
direction is of a line loopback type.
Payload Loopback
For a Payload Loopback, the T1 data is looped back
toward the network. The framing pattern, CRC6 calcu-
lation, and FDL bits are not looped back.
Line Loopback
For a Line Loopback, the T1 data is looped back toward
the network with framing and line coding unchanged.
Remote In-band Loopback
A Remote In-band Loopback initiates the transmission
of an in-band line loopback code toward the far end as
specified in ANSI T1.403.
Remote Line Loopback
A Remote Line loopback initiates the transmission of a
Facility Data Link (FDL) line loop up code toward the
far end as specified in ANSI T1.403. This loopback is
only available when the Total Access 1500 is provi-
sioned for Extended Superframe (ESF).
