Screen Reference
Interface
This field only appears when the Connect field is pbx; that is, when this DS1 link is providing an
ISDN-PRI connection in a private network. The Interface field controls how your server
negotiates glare with the far-end switch. The servers at either end of the DS1 link must have
complementary settings in this field: if not, the D-channel won't even come up. For example, if
the media server at one end of the link is administered as network, the other end must be
administered as user.

The entry in this field must match the companding method used by the far-end switch. This field
