FEATURE OPERATION:
The customer must contact the telephone company to have the CDND/BCLID service
initiated.  A service order is required.  This service is initiated on an 
individual customer basis for a PBX customer and on a customer group basis for
a Centrex or MLHG customer.  Parameter changes and possible hardware 
installation are required.  In addition, the customer will require CPE 
(e.g., a TTY, minicomputer, etc.) capable of receiving the ASCII formatted 
signaling that will be sent over a dedicated data channel.  Once the service
is initiated it will remain activated continuously until a request is made to
discontinue the service.

The output message containing the CDND/BCLID data goes over the dedicated data 
channel to the customer before ringing is applied to the called line.  The 
transmitted information is as follows:
 o CDND/BCLID Identifier
 o The date of the call
 o The time the call was made
 o The calling directory number
 o The line multistatus ("M" for PBX", MLHG, etc. and "T" for true DN)
 o The called directory number or terminal number and group number
 o The busy/idle status of the called directory number

TECHNOLOGICAL AND FEATURE INTERACTION CONSIDERATIONS:
1. This feature is available in the following central office switches:

Switch Type			1A ESS
Earliest Generic Release	1AE10*

Note:  * Available on an intraoffice basis with generic 1AE9.

2. The serving central office switch must be equipped with the appropriate
   CLASS CDND/BCLID software and hardware.  In order to provide call related
   information on an interoffice basis, both the originating and terminating
   switches must be equipped with the CLASS and Common Channel Signaling (CCS)
   SS7 software and hardware and the interoffice trunks must be converted
   to SS7.  This service is only offered on an intraLATA basis at this time.

3. When a customer has more than 10,000 calls per CDND/BCLID channel per hour,
   call related data for some calls may be lost.

4. Each CDND/BCLID directory number can have only one primary input/output
   channel and one backup channel to the 1A ESS Switch.

5. A PBX customer that wants to subscribe to BCLID must be assigned to a
   multiline hunt group or must be a PBX with DID.

6. CDND/BCLID output is not stored in the switch, therefore CPE must be
   available to collect the information.

7. The customer cannot activate or deactivate this service, it must be
   done via the service order process.
