Full Name

Description

SMJK

Remote SmartJack Loopback

DSX-1 signal is looped back to the network at the H2TU-R SmartJack

 

 

module.

 

 

DIAGNOSTIC MESSAGES

 

A = xx

Maximum Loop Attenuation

The Attenuation (A) message appears followed by xx, where xx is the

 

 

loop attenuation, measured in dB.

ACQ

Acquisition

The multiplexers of the H2TU-C and H2TU-R are trying to establish

 

 

synchronization over the HDSL2 loop.

AnL

Acquisition n Loop

The multiplexers of the two devices are trying to establish

 

 

synchronization with each other, where n is the number of the span.

ARM

HiGain System Armed

Armed to respond to Intelligent Repeater Loop (ILR) codes.

BAD RT?

No Response from H2TU-R

The H2TU-C receives no response from the H2TU-R and all HDSL2 loop

 

 

conditions are normal. Therefore, the integrity of the H2TU-R or the

 

 

HDSL2 loop is questionable.

FERR

Framing Bit Error Occurred

Framing bit error occurred at H2TU-C DSX-1 input.

FLDL

Flash Download

Flash download of firmware updates. Contact Customer Service for

 

 

update procedures (see “Appendix D - Product Support” on page 54).

HES

HDSL2 CRC Error

H2TU-C HDSL2 Loop Cyclical Redundancy Check (CRC) error.

LBPV

Local Bipolar Violation

A bipolar violation has been received at the DSX-1 input to the HiGain

 

 

Line Unit.

M=xx

HDSL2 Loop Margin

Indicates the power of the received HDSL2 signal relative to noise (S/N

 

 

with respect to 21.5 dB). Any value of 6 dB or greater is adequate for

 

 

reliable system operation.

MNGD

Managed

The HiGain Line Unit is under control of the HMU-319 Network

 

 

management unit. In this state, the front-panel craft port and push

 

 

buttons are disabled.

PWR FEED OFF

Power Feed Off

HDSL2 span power has been turned off by setting the PWRF option to

 

 

off, or HDSL2 span power has been turned off by use of the A2LB

 

 

Intelligent Office Repeater (IOR) Power Down code.

PWR FEED ON

Power Feed On

Indicates that the HDSL2 loop is not grounded or shorted.

SIG

Signaling

The transceivers of the H2TU-C and H2TU-R are trying to establish

 

 

contact with each other over the HDSL2 loop.

SnL

Signal n Loop

The transceivers of the two devices are trying to establish contact with

 

 

each other, where n is the number of the span.

 

 

SYSTEM INFORMATION MESSAGES (a)

 

CODE xxxx

Line Code: AMI or B8ZS

The line code that H2TU-C-388 is receiving at its DSX-1 interface, if the

 

 

DS1 option is set to AUTO. Otherwise, it mimics either of the other two

 

 

DS1 line code settings, Alternate Mark Inversion (AMI) or Bipolar with

 

 

8-Zero Substitution (B8ZS).

FRM xxxx

Frame: SF, ESF, UNFR

Defines the type of frame pattern being received from the DSX-1:

 

 

SuperFrame (SF), Extended SuperFrame (ESF), Unframed (UNFR).

LATT xx

Loop Attenuation

The current loop attenuation threshold setting measured in dB.

LIST xx

HiGain Line Unit List Number

The list number xx.

MARG xx

Margin

The current margin threshold setting measured in dB.

VER x.xx

HiGain Line Unit Software Version

The software version number (x.xx).
