Setting the ISDN Signaling (Switch) Type. The BRI interface must
implement the same type of ISDN signaling that your public carrier uses. (See
"Electrical Specifications for BRI ISDN" on page 3-9 to learn more about the
standards supported by the ProCurve Secure Router.) The signaling type does
not necessarily have to be that of the CO switch's manufacturer. For example,
a Lucent switch can implement National ISDN-1 signaling. Your telco should
inform you which signaling method it uses.
Consult Table 3-7 for the command syntax that implements each
signaling type.
Table 3-7. ISDN Signaling Types
Signaling Type
National ISDN-1
Euro ISDN
Northern Telecom DMS-100
Lucent/ATT 5ESS
For example, to set the signaling type to National ISDN-1, enter:
ProCurve(config-bri 1/3)# isdn switch-type basic-ni
The default settings are:
ISDN BRI U modules, isdn switch-type basic-5ess
ISDN BRI S/T modules, isdn switch-type basic-net3
Setting the LDN (Outside North America). The LDN is the local number
that remote routers call to reach the local router through the ISDN connection.
The peer at the other end of the connection includes this number in its backup
dial list. Unless you set an LDN, the interface cannot answer calls. It can,
however, still place calls if the public carrier supports connections without an
LDN. However, the peer might not answer the calls, depending on the its Caller
ID settings.
To set the LDN, enter:
Syntax: isdn ldn1 <LDN>
