		UNBALANCE – Unbalanced
		interface (BNC
		coax connectors)
ALB DTE, JP4	Enables local analog	EN – The local analog loopback
	loopback activation from	activation from the DTE is
	the DTE (via pin 18 for	enabled
	RS-530 or via pin “JJ” for	DIS – The local analog loopback	DIS
	V.35)	activation from the DTE is

disabled

Note: The JP4 jumper is not available for RIC-E1/R cards with X.21 or Ethernet interfaces.

PNL SW, JP5	Enables activation of the
	local analog loopback via
	the front panel pushbutton

EN – The LLB can be activated via EN the front panel

DIS – The LLB cannot be activated via the front panel

Note: The JP5 jumper is not available for RIC-E1/R cards with IR-ETH and IR-ETH/V interface modules.

For RIC-E1/R with IR-IP interface module, the JP5 jumper serves for enabling or disabling the IP LEARN pushbutton.

TX&RX CODE, JP6	Selects the data receive	HDB3	HDB3
	and transmit coding	AMI
TIMING SEL, J2	Selects the clock reference	RCV – Receive clock	RCV
		EXT – External clock
		INT – Internal clock

Note: Units with the IR-ETH, IR-ETH/V and IR-IP interface modules support only receive and internal clocks.

CHASS GND, J3 Controls the connection between the RIC-E1/R signal ground and the frame (chassis) ground

CON – Signal ground is	CON
connected to the frame
ground
DISCON – Signal ground is
disconnected from the
frame ground

Connecting the Cables

To connect cables:

1.Connect the E1 line interface.

2.Connect the DTE interface.

3.Connect the power cable (first to the converter, then to the mains supply). The PWR LED lights when power is connected.

2.Operating RIC-E1

RIC-E1 operates entirely unattended except when performing system tests.
