Managing trunks
344Adding a DID trunk group

2. In the Group Type field, type did.
This field specifies the kind of trunk group you’re creating.
3. In the Group Name field, type
Incoming calls.
You can type any name up to 27 characters long in this field.
4. Type
85 in the COR field.
This field controls which users can receive calls over this trunk group.
Assign a class of restriction that’s appropriate for the COR calling
permissions administered on your system.
5. In the TAC field, type
105.
This code identifies the trunk group on CDR reports.
6. In the Trunk Type field, type
wink-start.
This field tells the system what kind of signaling to use on this trunk group.
In most situations, use wink start for DID trunks to minimize the chance of
losing any of the incoming digit string.
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 Lucent 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.
