2. Configuring HCD-E1
You can configure and operate HCD-E1 from either the front panel or a
supervisory terminal.
Note
Some of the HCD-E1 configuration parameters depend on the type of remote
unit being used. Therefore, after the HDSL synchronization is reached, wait
for about 1 minute before you start configuring the modem. This allows the
proper recognition of the remote unit and ensures the correct HCD-E1
configuration.

Configuring

HCD-E1 from

Front Panel

To configure HCD-E1 from the front panel:
1. Scroll to the SYSTEM PARAMETER in the top row of the front-panel
LCD and set the system parameters (available for the HCD-E1 unit
configured as central).
2. Scroll to SL PARAMETERS in the top row of the front panel LCD and
configure the time slot allocation.
3. Scroll to CHANNEL PRM in the top row of the front panel LCD and, for
each data channel, configure the data rate, and time slot allocation.
This command also allows you to set several other data transfer
parameters, depending on whether or not the channel has an Ethernet
interface.
4. If your application explicitly requires the use of the unframed mode,
select it under SL PARAMETERS or CHANNEL PRM. Make sure to
assign all 32 times slots to the active port.
5. Scroll to DNLOAD PRM in the top row of the front panel LCD and set
the parameters for inband transmission of management data.
Note
The inband transfer of the management traffic is not available in the unframed
mode.
The remote unit automatically downloads the configuration of the central
unit, unless the CONFIG REMOTE parameter in the SYSTEM PARAMETER
screen of the central unit is set to NO.

Configuring

HCD-E1 from

Control Terminal
If you want to manage HCD-E1 from a remote supervisory terminal, you
must prepare the unit by setting its control port parameters from the front
panel:
1. Scroll to SP PARAMETERS in the top row of the front panel LCD.
2. Set the speed, data rate, parity, interface, and management mode
parameters for the control port.
To configure HCD-E1 from a control terminal:
1. Configure the terminal as follows:
Select full-duplex mode.
Turn the terminal echo off.
Disable any type of flow control.
