Page 1716 of 3156 Incoming DID Digit Conversion
553-3001-306 Standard 10.00 January 2002
When DEXT = YES (LD 16) the Attendant Console display looks like this:
AAAA:MMM#:xxxx iiii
where:
AAAA = route access code
MMM = Route Member Number
# = Special character (identifying the received digits)
xxxx = originally dialed digits, and
iiii = Internal DN (called party).
Incoming Call Redirection
If an incoming call is redirected to a Centralized Attendant Services (CAS) or
local attendant, the local DN is used to extend the call. If an incoming call
reaches a Night DN, Hunt DN, Call Forward DN, or similar destination, then
both the internal DN and the directory of local DNs are used to redirect the
call.
Operating parameters
IDC applies to Direct Inward Dialing (DID) routes only. Auto-terminate
trunks to Dialed Number Identification Service (DNIS) do not support IDC.
All digits received from an incoming call translate to a maximum of four
digits. Acceptable received digits for an incoming call are 0 through 9.
New Flexible Code Restriction (NFCR) is required to operate IDC. Since
NFCR trees and IDC tables share the same structure, the total combined
number of NFCR trees and IDC tables cannot exceed 255 per customer.
Feature interactions
Digital Private Network Signaling System (DPNSS1)/Digital
Access Signaling System (DASS2) Uniform Dialing Plan (UDP)
Interworking
An IDC table can be used to convert digits received on a DASS2 DID trunk
into a digit string having the UDP format. This allows a DASS2 DID call to
access the DPNSS1 UDP network.
