(CRC), or BER errors.
Red HDSL2 LOSW detected.
Yellow Brief Flash: HDSL2 CRC error on any segment of indicated loop.
Steady: BER threshold exceeded on indicated HDSL2 loop, (default is 10
Flashing Green HDSL2 activation in progress.
Green Normal operation.
PROT LED Indicates which of the two loops is transmitting the HDSL2 payload.
(Version C1P only)
Green Loop 1 is transmitting the HDSL2 payload.
Yellow Loop 2 is transmitting the HDSL2 payload.

OGGING ON TO THE
The Versions C1 and C1P H2LXC modules support system logon through a maintenance
terminal (VT100 or a PC running VT100 terminal-emulation software) connected to the
craft port on the SCU front panel. Once logged on, you can access the Main Menu screens
to view local and remote system settings, initiate loopbacks, and provision the circuit.
To log on and access the Main Menu screens using a maintenance terminal:
ENTER
1 Press the key once to display the Logon screen.
2 Type the assigned logon ID in the Enter User Name field. If a logon ID is not
SONEPLEX
assigned, type (default), then press
3 Type the assigned password at the Enter Password field. If a password is not
assigned, type SONEPLEX1 .
ENTER
4 Press the key to view the Main Menu screen..
For more detailed information, refer to the Soneplex Loop Extender
Operation and Maintenance Manual, or the Soneplex Broadband
System Operation and Maintenance Manual. They can be downloaded
from the ADC web site at www.adc.com.

OOPBACK
Initiate loopback testing from the maintenance terminal menus or by using inband codes.
The inband codes shown in
on loopbacks, refer to the technical practice ADCP-TP-61-314-08. It can be downloaded

ROTECTION
The Version C1P H2LXC module supports automatic 1+1 facility protection switching
when connected to a Version C1P H2LXR remote unit. The copper span must be
configured using two loops. Loop 1 is initially activated as the working pair, leaving Loop
2 as the protect pair. The H2LXC feeds line power to the H2LXR over the working pair and
applies metallic sealing current to the H2LXR over the protect pair to verify its integrity.
Switching is initiated by one of three actions:
•
Manual: Press the PROT pushbutton on the front panel of either unit for 5 seconds.
• Forced: Select the FORCED SWITCH option from the SCU craft port on the HDSL2
protection switching maintenance screen.
• Automatic: Enable one of the HDSL2 performance parameters: BER and LOSW,
BER, LOSW, or DISABLE (lockout).
The BER values are selectable from 10
default switching option is BER (10
(lockout), the system will not revert but will remain active on the protect loop until one of
the following manual intervention actions occurs:.
• The H2LXC module is removed and reseated.
• A manual switch is initiated from the front panel of either unit.
•
A forced switch is invoked from the SCU craft screen.
• A RE-ENABLING command is invoked from the SCU craft screen.
An alarm is generated when there is no sealing current flowing on the protect loop, except
when the loop contains a repeater. The sealing current feature is inhibited on repeatered
spans. Although a loop 1 – loop 2 reversal does not interfere with protection switching, the
H2LXR detects the condition and reports it to the H2LXC to alert the user .
