Your modem ships from the factory with the Synchronous Leased (Answer) default configuration options stored in memory. If Synchronous Leased (Originate), Asynchronous Leased (Answer or Originate), Trellis Multipoint (TMp) (Control or Tributary), Async Dial, Sync Dial, or UNIX Dial is more appropriate for your configuration, then you must change the factory setting using either the modem’s DCP or the AT command set as described in the following sections.
