Parameters
protocol: Specifies an ISDN switch type. Available options
include 5ess, ansi, at&t, dss1, etsi, ni, ni2, ntt, and qsig. To specify ANSI, AT&T, ETSI, NI, or NTT,
make sure the interface is operating on the user side.
Usage guidelines
You can configure the command only when no call is present on the ISDN interface.
ISDN service providers in different countries implement variants of ISDN to provide varied ISDN
services. When you configure an ISDN interface, you must set the switch type on the interface to be
the same as the service provider switch type.
Table 38 shows the ISDN switch types available on an ISDN interface.
