1 thirty second test

Special Note: For Adtran HDSL2 cards used in a Litespan application. Although the Adtran card is shipped with a

line code of B8ZS, the Litespan will change that value to the Litespan automatic default of AMI. The Central Office,

NOC or SSTC must provision the Litespan to ensure proper line code information is set in the system.

SSIM, ATT Midwest ONLY: SPECIAL BOOT PROCESS WHEN T1 “RIDES” ON A LITESPAN SYSTEM

When adding DS1 cards to an existing Litespan system, a “boot proc” is performed. The SSIM technician will need to

verify the software version in the card is the same as the latest software release. If not the same,a boot process will

ensure the newest software version is loaded onto the Litespan element. This process only applies to the new card

being installed in the Litespan. Doing this on existing cards will cause a momentary hit to service. If a card already is

in the Litespan slot ( previous disconnected circuit), and the service is new, the same "boot proc" must be

done.

To determine if boot proc must be done on a DS1 card for a new circuit installation:

•

retrieve equipment for that card, this will show you what the software release is. Ex: (10.02.02)

•

Retrieve version, this will show the latest software version. (11.02.02)

•

If the software versions do not match, follow the Boot Proc below.

To Boot Proc the DS1 card:

•

Display " boot proc" procedure. This procedure is found in the TL1 Messages section under BOOT-PROC.

This process must be done on new installs, when the card is reused if the software versions do not match. This

procedure is for ATT Midwest only. The NOC normally does this process in other regions.

On HDSL Cards:

•

Date and time must be set.

•

Actual pair loss for HDSL and HDSL2 should not exceed -35 dB at 196 kHz using a 135 # termination per link or

section. This is not a required test.

•

Actual pair loss for HDSL4 should not exceed -44 dB at 196 kHz using a 135 # termination for circuits not using a

regenerator or on the first link ( CO to regenerator) of a circuit using regeneration. Actual pair loss on the second

link ( regenerator to premise) should not exceed -41 dB at 196 kHz using a 135 # termination.

•

Sync light should be green for Adtran units. For ADC/Pairgain, reading should be between -64 to +64 for good

synchronization.
