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.
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.
Under the E&M Signal heading, select one of the following signaling types

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.
NOTE:
The 1C option assumes that the two systems are connected together
without any provisioned facility, and without any signaling treatment
equipment.
If the tie trunks are connected directly to a system that uses type 5
signaling and is located near this system, check 5.
Under the Inmode heading, check either the Touch-Tone column or
Rotary column (factory setting) for each incoming-only and each
two-way tie trunk.
