Use Attendant Control of Trunk Group Access
If direct access to trunk groups must be allowed, consider making them
attendant-controlled trunk groups. The attendant can then screen the calls.
Up to 12 trunk groups can be controlled.
For DEFINITY ECS, DEFINITY G1, G3, and System 75:
 Enter change attendant to display the Attendant screen. In the Feature
Button Assignment field, enter
act-tr-grp and deact-tr-grp to
activate and deactivate attendant control of a trunk group.
 Enter the corresponding Trunk Access Code in the Direct Trunk Group
Select Button Assignment field.
 Press the act-tr-grp button to activate Attendant Control of the trunk group.
NOTE:
This affects all users, not just Remote Access users. If calls are
dialed via AAR/ARS/WCR, these trunks will be skipped in the routing
pattern.
For DEFINITY G2 and System 85:
 Enter PROC350 WORD2 FIELD1 = 20 to assign a FAC (System 85) or a
Dial Access Code (DAC) (G2) that activates the attendant control feature.
 On the attendant console, press the deactivate button to deactivate the
code.
 Each controlled trunk group requires a console key with trunk status
indicators.
NOTE:
ARS/WCR skips over a trunk group under attendant control. Only
when no other route is available will ARS/WCR select an
attendant-controlled trunk group.
Disable Facility Test Calls
The Facility Test Call feature provides the ability to make test calls to four types of
facilities to ensure the facility is operating properly. The following types of calls are
available to both local voice terminal users and Initialization and Administration
System (INADS) terminal users:
 Trunk test call — Accesses specific tie or CO trunks, but not DID trunks.
 Touch-tone receiver test call — Accesses and tests the four touch-tone
receivers located on a Tone Detector circuit pack or the eight receivers if a
TN744 Call Classifier circuit pack is used.
