both directions, over a single copper telephone line.
The 7996-A2-374 has an industry standard E1 interface. Based on TC-PAM coding, the
7996-A2-374 supports data rates of up to 2,048 kbps. It is suitable for leased line applications
such as video conferencing, Internet access, and Digital Data Network (DDN) access.
Featuring remote control capability, the local 7996-A2-374 is able to perform configuration,
performance monitoring, querying, diagnostics, and all maintenance functions over the remote
NTU via the DSL line.

by ATM-based NTUs
Full remote control capability via SHDSL Embedded Operation Channel
Complies with ITU-T G.991.2 (G.shdsl)
E1 DTE interface
Versatile loopbacks for diagnostics
Built-in test pattern generator and detector
SHDSL and E1 line performance monitoring (PM)
96-quarter-hour / 7-day PM storage

1.4 Front Panel LED Indicators
The 7996-A2-374 has eight LED indicators. These LEDs indicate power status, diagnostics,
machine status, data activity, and alarm conditions.

Note: The average training period for the SHDSL line is one minute and forty seconds. If the training
period exceeds three minutes, or it fails (the DSL LOS LED keeps blinking), it means the line
quality is poor or the link distance is too long for the SHDSL NTU to train. Contact your service
provider.

Chapter 2 Hardware Installation
2.1 Rear Panel Connectors
There are two types of rear panels for the 7996-A2-374. Their only difference is the power
supply: –48 VDC or 110/220 VAC.
Figure 2-1 7996-A2-374 Rear Panel Connectors – DC power
Figure 2-2 7996-A2-374 Rear Panel Connectors – AC power
Interface Description
–48V FG PG
Power
The –48 VDC version has three pins: –48V, FG, PG (Fig.2-1).
The AC version has a power jack and a power switch (Fig.2-2).
Console DB9 female connector for connection to a PC COM port
LAN RJ45 connector for SNMP network management
E1 RJ45 connector for a 120 ohm, balanced E1 interface
TX and RX BNC connector for a 75 ohm, unbalanced E1 interface
LINE RJ45 connector for the SHDSL connection

2.2 Installation
Follow the step-by-step instructions below for the hardware installation:
Connect the LINE port to your DSL line. Step 1
Step 2
Step 3
Step 4
Step 5
Connect the LAN port to the SNMP management network with an RJ45 connector cable.
Connect the E1 interface to the Data network.
Connect the Console port to the VT100 compatible terminal or PC COM port with an
RS232 cable.
Connect the Power to the power input.
For the DC version, connect the power pins as follows:
–48V: Connect to –48VDC power supply source.
PG: Connect to the ground of –48VDC power supply source.
FG : Connect to the frame ground.
For the AC version, connect the Power jack to the power cable of the 110 or 220 VAC power
adapter.
Step 6
After power on (for the AC version, turn the power switch to the ON position), the
7996-A2-374 performs a self-test. During the self-test, all LEDs will keep flashing back
and forth sequentially. The test items include system RAM, flash memory and application
software. If an error is found in RAM, the ALARM LED will be ON. If an error is found
in flash memory or application software, the ALARM LED will keep flashing.
Caution: If the SHDSL NTU fails to power on, or it malfunctions, first verify that the
power supply is correctly connected, and then power it on again.

STEP 3:
In Windows, click on Start and choose Run. Type:
telnet xxx.xxx.xxx.xxx.
where xxx.xxx.xxx.xxx is the IP address of your SHDSL NTU. The default NTU IP
address is 172.16.7.37.
Refer to Chapters 4 to 6 to configure and maintain the SHDSL NTU.
3.3 SNMP Management
