3 Lines/Trunks
Selecting Line/Trunk Options
NOTES:
1. Check the same signaling type used by the system to which you are
connecting. For incoming-only or two-way tie trunks, the incoming type
must be the same as the outgoing type of the remote system. For
outgoing-only or two-way tie trunks, the outgoing type must be the same
as the incoming type of the remote system.
2. Wink is the factory setting and is the preferred type, followed by Delay
then Immediate. Immediate does not work with touch-tone dial mode.
Use Delay for private networks.
3. Immediate Dial incoming signaling is required if the CO switch is an AT&T
5ESS or Northern Telecom DMS-100 and incoming calls are
administered to route by Line Appearance. Immediate Dial outgoing
signaling should not be used for digital emulated Tie trunks using T1
Switched 56 service due to the lack of trunk integrity checking.
4. Dial-in E&M Tie trunks cannot be assigned to ring into a DGC group. Only
Auto-in Tie trunks can be assigned to ring into a DGC group.
4. Under the E&M Signal heading, select one of the following signaling types
to be used on the tie trunks:
One-way, Outgoing Tie Trunks. All outgoing calls are placed using
Automatic Route Selection, and tie trunks are not assigned to
personal line or Pool buttons on telephones. Select wink signaling.
One-way, Outgoing Tie Trunks. Tie trunks are assigned to
personal line or Pool buttons on telephones. Select immediate
signaling.
One-way, Incoming Tie Trunks. Dialed Number Identification
Service (DNIS) is included. Select wink signaling.
NOTE:
E&M Signaling does not apply to digital emulated Tie trunks using T1
Switched 56 service and should not be set during administration of
those trunks.
If the tie trunks are connected to the other system through the local
telephone company, check 1S (the factory setting).
If the tie trunks are connected directly to a system that uses type 1S
signaling and is located near this system, check 1C.
