							Features Description 
Direct Inward Dial (DID) Trunks 
Description 
Direct Inward Dialing (DID) allows subscribers on the Public Switched 
Network to have direct access to PABX extensions without Attendant as- 
sistance. The Central Office (CO) transmits the desired destination 
number to the PABX. 
The trunk’s Class of Service controls DID caller access to features and 
services. 
Conditions l 
. 
. 
. 
. 
. 
. 
Refer to TRUNK INTERCEPTS in this Section for further conditions.  DID trunk calls apply Discriminating Ringing to the destination set. 
If the SX-50 system receives too few digits from a DID trunk, it returns 
reorder tone. 
If the SX-50 system cannot complete the DID call due to unavailable 
call-handling resources or blocking, it returns reorder tone to the 
trunk. 
A DID Trunk must not be a member of any Trunk Group. 
A DID Trunk must not be programmed as a SUPERSET DTS or DLS 
line. 
All DID calls that are terminated on an answering device will return An- 
swer Supervision.

Programming Digit Collection From The CO 
The SX-50 system collects and modifies digits from the Central Office (CO) 
to determine the intended destination. The number of digits received is 
determined by prior arrangement with the telephone company. If this is less 
or more than the number of digits in the directory number, the SX-50 system 
can add or delete digits as appropriate. Three fields are provided to 
accomplish this: 
l N: the number of digits expected from the central office (1 to 9). If a 
value is specified in this field, digit translation does not begin until the 
system receives the specified number of digits. 
l M: the number of digits to be absorbed after the incoming trunk is 
seized (0 to 8). 
l X: up to 4 digits to be inserted before the digit string. 
Command 501 - 580, Trunks 01 - 80 Programming, Register 6: 
l Set Digits Expected, N, (field e) to 1 -+ 9, as required.

Features Description 
Direct Inward System Access-(DISA) 
Description 
Direct Inward System Access (DISA) allows a trunk caller direct access to 
the PABX without attendant intervention. A DISA Trunk user hears one 
burst of ringback tone before the SX-50 system automatically answers 
and provides DPABX dial tone. - 
A 3-digit DISA Access Code or Verified Authorization Code can be required 
at this point. The caller must enter the code, after which DPABX dial tone is 
returned. If the DISA Access Code is not required, the DISA caller has 
access to PABX features immediately. For further details on Verified 
Authorization Codes, refer to SPECIAL DISA or TRAVELING COS in this 
Section. 
Conditions l DISA calls to the Attendant follow the trunk’s Day Answer Mode or 
Night Answer Mode routing, as appropriate. The default routing is to 
LDNl during Day Service, Night Bell during Night Service. 
l On some Central Offices, the DISA caller might not receive an entire 
cycle of ringback tone. If this occurs, enable Inward Dial Delay Before 
Answer. See Programming. 
A DISA call cannot: 
l Be executed from a rotary set 
l Flash the switchhook 
l Override 
l Call forward 
l Put on an Automatic Callback - Busy 
l Be from an Identified Trunk Group. 
DISA Trunks can dial access codes for the following devices only: 
l Extensions 
l Attendant Console 
l Pager (DISA Trunk must provide Disconnect Supervision) 
l Trunks (trunk-to-trunk connection conditions must be met) 
l RMATS. 
DISA Trunks cannot access codes for the following devices: 
l TAFAS 
l Feature Access Codes requiring a flash to activate 
l Call Forwarding

							Features Description 
l Attendant Console functions (except through RMATS) 
l System administration (except through RMATS).

CO provides Disconnect Supervision and is programmed accordingly. 
Refer to TRUNK INTERCEPTS in this Section for further conditions.
