Adding a DIOD trunk group
Issue 5 October 2002 419555-233-506
7. In the Incoming Dial Type field, type tone.
This field tells the switch how digits are transmitted for incoming calls.
Entering tone actually allows the trunk group to support both ‘‘DTMF’’
and rotary signals, so Avaya recommends that you always put tone in this
field.
8. In the Trunk Termination field, type
rc.
Use rc in this field when the distance to the central office or the switch at
the other end of the trunk is more than 3,000 feet. Check with your service
provider if you’re not sure of the distance to your central office.
9. Press
ENTER to save your changes.
Now you’re ready to add trunks to this trunk group. See ‘‘Adding trunks to a trunk
group’’ on page 430.

Adding a DIOD trunk group
Administration for Direct Inward and Outward Dialing (‘‘DIOD’’) trunk groups
varies from country to country. See Avaya MultiVantage™ Application Notes for
Type Approval, and use the DS1 screen illustrations in the chapter for your
country as a model for your administration. Remember that the central office
serving your switch may be emulating another country’s network protocol. If so,
you’ll have to administer your circuit packs and trunk groups to match the
protocol used by your central office.
!
SECURITY ALERT:
If you’re using Incoming Caller ID (‘‘ICLID’’) on analog trunks connected
to a DIOD Central Office trunk circuit pack, DO NOT put these trunks in an
outgoing AAR or ARS route pattern. Since the loop-start trunks supported on
the DIOD Central Office trunk circuit pack do not provide answer
supervision, the potential for toll fraud exists.
