Configuring ISDN Services Physical and Logical Interface Properties

To configure ISDN services physical interface properties, include the isdn-options statement at the [edit interfaces br-pim/0/port] hierarchy level:

[edit interfaces br-pim/0/port]
isdn-options {
calling-number number;
incoming-called-number number <reject>;
pool pool-name <priority priority>;
spid1 spid-string;
spid2 spid-string;
static-tei-val value;
switch-type (att5e | etsi | ni1 | ntdms100 | ntt);
t310 seconds;
tei-option (first-call | power-up);
}
dialer-options {
pool pool-name <priority priority>;
}

To configure ISDN services logical interface properties, include the following statements:

[edit interfaces dln unit logical-unit-number]
dialer-options {
activation-delay seconds;
callback;
callback-wait-period time;
deactivation-delay seconds;
dial-string dial-string-numbers;
idle-timeout seconds;
incoming-map {
caller (caller-id| accept-all);
initial-route-check seconds;
load-interval seconds;
load-threshold percent;
pool pool-name;
redial-delay time;
watch-list {
[ routes ];
}
}
encapsulation [
(cisco-hdlc | multilink-ppp | ppp);
}
}

To configure a primary interface to use an ISDN logical interface as a backup or “failover” interface when the primary connection experiences interruptions in Internet connectivity, include the backup-options statement to specify the ISDN interface at the [edit interfaces interface-name unit logical-unit-number] hierarchy level:

[edit interfaces interface-name unit logical-unit-number]
backup-options {
interface dln.0;
}

You can include these statements at the following hierarchy levels:

To configure the Services Router to reject incoming ISDN calls (supported when dial-in is configured), include the reject-incoming statement at the [edit system processes isdn-signaling] hierarchy level:

[edit system processes isdn-signaling]
reject-incoming;
}

To disable ISDN, include the disable statement at the [edit system processes isdn-signaling] hierarchy level:

[edit system processes isdn-signaling]
disable;
}

To disable the dial-out on demand process, include the disable statement at the [edit system processes dialer-services] hierarchy level:

[edit system processes dialer-services]
disable;
}
