PBX-1
Dials "7-902" + a DISA
floating extension number of PBX-2
The TIE Line Access number was dialed, therefore PBX-1 checks its TIE Line Routing
and Modification Table (not shown here). Finds leading number "902". No modification is
programmed.
PBX-1 removes the TIE Line Access number and sends the remaining digits down the
TIE line. The number is now "902" plus the DISA floating extension number of PBX-2.
PBX-2 checks its Incoming Number Modification Table (not shown here). No modification
is programmed.
PBX-2 recognizes its own PBX code and sends the call to its DISA feature. From this
point, if the COS assigned to the caller's extension or verified code allows, the caller can
use Walking COS or Verified Code Entry to bypass the restrictions and make a CO line
call.
