3Com Router Command Reference Guide Addendum for V1.2
Parameter
dss1: DSS1 (Digital Subscriber Signaling No.1) signaling is used.
ni: National ISDN signaling is used.
Description
Using the isdn protocol-type command, you can configure signaling to be used at
the ISDN interface.
By default, DSS1 signaling is used.
When this command is used in System view, it will set the default signaling for the
ISDN interface configured on a router, but it will not affect the type of signaling on an
existing ISDN interface.
When this command is used in Interface view, it will set the type of signaling for the
active ISDN interface. However, if there are calls on the interface, configuring this
command will not take effect.
Note:
You are allowed to configure:
DSS1 ISDN on BRI, E1 PRI, and T1 PRI interfaces;
NI (National ISDN) on BRI interfaces;
Other protocols are made up by the negotiation commands of Layer 3 protocol under DSS1 protocol.
For related commands, see display isdn call-info.
Example
Configure the router to use NI signaling at the interface BRI0.
