DTE Interface Type • V.35: 34-pin, female
• X.21: 15-pin, D-type female
• V.36: 37-pin, D-type female, via adapter
cable
• RS-530: 25-pin, D-type female
• IR-ETH: RJ-45 or BNC
• IR-ETH/V: RJ-45
• IR-IP: RJ-45
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
For description of the IR-ETH, IR-ETH/V and IR-IP interface modules, refer to
Appendix B , Appendix C , and Appendix D , respectively.
