Ports
The card provides the four BRI ports whose details are tabulated in
table 11
. Each one is terminated internally
at 100 ohm. See appendix C,
“Cabling”
on page 142 for connection cable and appendix D,
“Port pin-outs”
on

Description
BRI 0
ISDN BRI RJ-45 socket that connects the SmartNode with an ISDN terminal over an S or S/T interface.
BRI 1
ISDN BRI RJ-45 socket that connects the SmartNode with an ISDN terminal over an S or S/T inter-
face. BRI 2 may be used as a fallback in conjunction with BRI 1. See ‘Hardware Bypass’ below.
BRI 2
ISDN BRI RJ-45 socket that connects the SmartNode with an ISDN device over an S or S/T inter-
face. The pin out and protocol is software configurable. BRI 1 may be used as fallback in conjunc-
tion with BRI 2. See ‘Hardware Bypass’ below.
BRI 3
ISDN BRI RJ-45 socket that connects the SmartNode with an ISDN device over an S or S/T inter-
face. The pin out and protocol mode is software configurable.
