ADTRAN SHDSL NxNTU specifications Front Panel Pushbuttons, Button Label Description

Page 3

The Express 6530 has four front panel pushbuttons. The buttons are protected from accidental operation. The front panel button functions can be disabled via the management interface. It is possible to disable the port select SHDSL option to avoid the possibility of looping the SHDSL port when disabled. Table 2 lists and describes these four pushbuttons.

The “Port Select” button operates in the following manner:

1.When no port has been selected (indicated by none of the port LEDs flashing), then only the “Port Select” button is enabled and the LL, RL and BERT LEDs are an ordered summation of the test states of the Nx64k, G.703 and SHDSL interfaces.

2.The Port Select button cycles through the following ports on each successive press:

Nx64k

G.703

SHDSL (only if enabled via the EOC)

No Selection

3.When the Nx64k port is selected, the Nx64k LED will flash as an indication. The Local Loop/Err Inj, Remote Loop and BERT buttons will initiate/ terminate tests and the corresponding LEDs indicate the status of tests on this port only.

4.When the G.703 port is selected, the G.703 port LED flashes as an indication.

If there is only a single service on the G.703 port then the Local Loop/Err Inj, Remote Loop and BERT buttons initiate/terminate tests and the corresponding LEDs indicate the status of tests on this port only.

If there are multiple services, the G.703 port Local Loop/Err Inj, Remote Loop, and BERT buttons are disabled, and the corresponding LEDs indicate the status of tests on this port only (initiated from sources other than the front panel buttons).

5.When the SHDSL port is selected, the SHDSL port LED flashes as an indication. Note that the SHDSL port select can only occur if enabled via the management interface. The Local Loop/Err Inj, Remote Loop, and BERT buttons will initiate/terminate tests and the corresponding LEDs indicate the status of tests on this port only. These tests are on the aggregate SHDSL payload

Port Select will not operate if any locally initiated tests are in progress.

Description

 

 

 

PORT SELECT

 

On each successive press, cycles through the following:

 

Nx64k, G.703, SHDSL, and No Select.

 

 

 

 

 

 

 

If a port is selected, and a BERT is not in progress then

LOCAL LOOP/ ERR INJ

 

pressing the button will initiate/terminate a local loopback

 

test on the selected port. If a BERT is in progress, then

 

 

 

 

pressing the button injects a single bit error.

 

 

 

REMOTE LOOP

 

If the SHDSL port is selected, then pressing the button will

 

 

initiate/terminate a remote loopback test on the port by

 

 

sending a request message to the remote unit. If the

 

 

Nx64k port or G.703 port (with only one service defined)

 

 

is selected, then pressing the button will initiate/terminate a

 

 

remote loopback test on the selected port's single data

 

 

service by sending in-band loop up/down patterns to the far

 

 

end.

 

 

 

 

 

If a port is selected and there are no local loopback tests

BERT

 

active, then pressing the button will start or stop a BERT

 

 

on the selected port.
