RS-530 or via pin “JJ” for
V.35)
EN – The local analog loopback
activation from the DTE is
enabled
DIS – The local analog loopback
activation from the DTE is

TIMING SEL, J2 Selects the clock reference RCV – Receive clock
EXT – External clock
INT – Internal clock
RCV
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

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