FEATURE OPERATION:

1. The message desk or VMP has the option of having 7 or 10 digit originating
   subscriber's directory numbers, as well as the reason the call is being
   forwarded, delivered to the message desk or VMP's Customer Premises
   Equipment (CPE).  The information package to the message desk or VMP,
   delivered in real time over the Dedicated Network Access Link (DNAL), 
   includes the MLHG and terminal identification of the call handler, call
   reason (call forward type or direct call), originating caller's directory
   number, and originally called number in the forwarding situation.  
   Information will be passed over a DNAL when the CPE and the message desk or
   voice messaging subscribers are connected to the SS7 network.  The message
   desk or VMP must have some type of CPE to receive and interpret the 
   Simplified Message Desk Interface (SMDI) data.

2. The call forward type includes Call Forwarding Busy Line, Call Forwarding
   Don't Answer, Call Forwarding Variable (forwarding of all calls), and
   direct ESP call.

3. The DNAL may be utilized by the CPE to activate the stutter dial tone, more
   commonly known as the Message Waiting Indicator (See: Remote Activation of
   Message Waiting - Expanded, and/or Message Waiting Indicator - Ability to
   Activate Audible/Visual Message Waiting).
