		Control Signals	V.35, X.21, RS-530:
			•	CTS follows RTS
			• DCD follows E1 state
			V.35, RS-530:
			• DSR is constantly ON
Timing			Derived from three alternative sources:
			•	Internal oscillator
			• External, from the attached DTE
			• Receive, derived from the received signal
Indicators		PWR (green)	On – RIC-E1 is powered
		TXD (yellow)	On – Data is being transmitted to the link
		RXD (yellow)	On – Data is being received from the link
		LOS (red)	On – No E1 data is received from the link
		TST (red)	On – The local loopback is active
	Note	For description of the IR-ETH, IR-ETH/Vand IR-IP interface modules, refer to
		Appendix B, Appendix C, and Appendix D, respectively.
