Front Panel
The front panel provides control over the unit operation. The LEDs provide
real-time indications related to the operation and status of the unit.
The LCD together with three push-button switches are used to display
status (alarm) messages, diagnostics and performance monitoring data, test
status and configuration parameters of HCD-E1. You can also use the LCD
and push buttons to configure the unit. For details, see Chapter 3,

Data Channel
Characteristics
HCD-E1 data ports support user-selectable transmission rates. The supported
data rates are integer multiples of 56 kbps or 64 kbps (n × 56 kbps or
n × 64 kbps, where n is in the range of 1 to 32, corresponding to rates in the
range of 56 kbps to 1792 kbps, or 64 kbps to 2048 kbps respectively).
HCD-E1 supports the following types of data port interfaces: RS-530, V.35,
X.21, V.36/R-449/422 and IR-ETH (10BaseT or 10Base2), IR-ETH/Q
(10BaseT) or IR-IP (10BaseT).
HCD-E1 has two data ports, each terminated in a 25-pin D-type female
connector. The units with an Ethernet interface arrive with the Ethernet
interface module built in the upper port.
When using the RS-530 interface, equipment with RS-530 interface can be
directly connected to the data channel connector using standard cables.
Equipment with V.36/RS-422/RS-449, X.21 and V.35 interfaces can be
connected by means of adapter cables, supplied with the unit.
