Revision History
This is the fourth issue of this practice. This issue
reflects updates to the Total Access 1500 System
Software Release 3.0, Dual LIU software T07D, and
incorporates the addition of new features including:
• Changed
CLK OOS Alarm in Alarms menu to
Disable as factory default
• Incorporation of automatic mapping for 2B+D
ISDN when in Dual T1 mode
• Removed signaling bits from 4-wire TO
A full list of features is detailed in Total Access 1500

NOTE
This release of the LIU software is designed to
operate with System Controller Unit (SCU)
software release V08 or later to support these
feature enhancements.
Description
The Dual LIU is a common module for the Total Access
1500 chassis (P/N 1180001L1) or the Total Access
1500 19-inch chassis (P/N 1180019L1).
The Dual LIU connects the chassis to a T1 line at the
DSX-1 or DS1 level. All data formatting and line
encoding as well as backplane timing and control are
performed by the Dual LIU.

4. ALARMS

5. TESTS

Loopback Tests

Initiated from site manager or ADMIN port, these tests aid circuit turnup and maintenance efforts.

Local Loopback

T1 data is looped back toward the customer after passing through the framer and LIU circuitry.

Line and Local Loopback

A bi-directional loopback via menu access only, with the loopback in the network direction being a line loopback type.

Payload Loopback

T1 data is looped back toward the network; framing pattern, CRC6, and FDL bits are not looped back.

Line Loopback

T1 data is looped back toward the network with framing and line coding unchanged.

Remote In-band Loopback

Initiates an in-band line loopback code toward the far end as specified in ANSI T1.403.

Remote Line Loopback

Initiates a Facility Data Link (FDL) line loop up toward the far end as specified in ANSI T1.403.

Remote Payload Loopback

Initiates a FDL Payload loop up code toward the far end as specified in ANSI T1.403.
