Switch Protocol—NET5/CTR4 is the default. It is the

standard ETSI protocol derived from ITU Q.931.
If you change the country settings, a new set of PRI switch
protocols is loaded.
If the current switch protocol is no longer available, you are
prompted with "Do you wish to continue?" If you do, the
current switch protocol is changed to the default for the selected
country. This causes a reset of the PRI interface.
If more than one switch protocol is supported, you must find
out from the telephone service provider which protocol to
select.
The PRI network interface module originates and accepts data
calls only, and does not work with incoming PRI choice calls or
non-PRI lines of any kind. Special services, such as caller-id,
blocking, and call forwarding, are not supported.
If you have a PRI T1 network interface module, the following screen
appears:
