1004 Call Redirection - Packet

Call Redirection is an optional intraLATA Public Packet Switched Network (PPSN)
feature that allows the network to automatically redirect calls to a predefined
backup DTE (Data Terminal Equipment) under specified conditions.  The primary 
DTE may designate a list of secondary DTEs called a back-up list.  The network 
may be able to search the list in sequence until a connection can be 
established.

FEATURE OPERATION:
The PPSN will provide the calling clients DTE/CPE with the address and reason
for redirection of the call to a secondary DTE.  The network will also provide
the secondary DTE with data in the incoming call packet as to why the call
was forwarded and the address of the primary DTE.

TECHNOLOGICAL AND FEATURE INTERACTION CONSIDERATIONS:
1. The Packet Switch, Access Concentrator or ISDN Packet Handling Function 
   should support X.25 direct access interface.

2. LEC ISDN interface to PPSN should support X.75' CCITT recommendation.

3. PPSN supports both individual and hunt group DTE access.  Call Redirection
   applies to all addresses associated with subscriber access.

4. Call Redirection is limited to interfaces within a single LATA.

This service, if offered as a BSE, may be associated with the Packet Switched
X.25 and X.75 basic serving arrangements.
