VERSIONS C1 AND C1P H2LXC

The Versions C1 and C1P H2LXC Modules are HDSL2 plug-in units that install in a

Soneplex Broadband Chassis or Soneplex Loop Extender Chassis. When used in

system provides 1.544 Mbps full-duplex transmission on one unconditioned copper

pair over the full Carrier Service Area (CSA) range. The CSA includes loops of up to

12,000 feet on 24 AWG wire or 9,000 feet on 26 AWG wire, including bridged taps.

INSTALLATION

1 Align the module with the enclosure slot guides and slide the module in until it

touches the backplane connector.

2 Raise the extraction lever at the bottom of the front panel to press the module into

the backplane connector.

POWER-UP SEQUENCE

When the H2LXC powers up, the following occurs:

1 The STAT LED briefly turns red then yellow, indicating that the power is on and

that the self-test diagnostics is beginning. The remaining LEDs momentarily turn

yellow, then turn off.

2 The front-panel LEDs appear as follows upon successful completion of the

self-test diagnostics (refer to Table 1):

• STAT - Displays green

• RMT/HSKP - Off

• LPBK - (usually) Off

• DS1 LOS/BER - Off, red, or yellow (see Table 1 for detailed information).

• HDSL2 LOSW/BER - Initially displays red, then displays flashing green

until loops are synchronized.

VERSIONS C1 AND C1P

H2LXC M

ODULES

VERIFICATION

Once the H2LXC module is installed, verify that it is operating properly by monitoring the

Status LEDs on the front panel (see Table 1).

LOGGING ON TO THE MAIN MENU

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:

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

assigned, type

SONEPLEX (default), then press .

3 Type the assigned password at the Enter Password field. If a password is not

assigned, type

SONEPLEX1.

4 Press the key to view the Main Menu screen..

LOOPBACK TESTING

Initiate loopback testing from the maintenance terminal menus or by using inband codes.

The inband codes shown in Table 2 can be sent by a test set. For more detailed information

on loopbacks, refer to the technical practice ADCP-TP-61-314-08. It can be downloaded

from the ADC web site at www.adc.com.

COMPATIBILITY

The following table shows the compatible units in an H2LX system and the various

transmission distances possible with and without a repeater.

PROTECTION SWITCHING OPERATION

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

-3

to 10

-9

and are based on HDSL2 CRC errors. The

default switching option is BER (10

-6

) and LOSW. Once an automatic switch has occurred

(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 .
