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.Automatic incoming signaling is required if the CO switch is a Lucent Technologies 5ESS or Northern Telecom DMS-100 and incoming calls are programmed 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 calling group. Only Auto-in Tie trunks can be assigned to ring into a calling group.

■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.

4.Under the E&M Signal heading, select one of the following signaling types to be used on the tie trunks:

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. When connecting a MERLIN LEGEND switch to another MERLIN LEGEND switch, use 1C on one switch and 1S on the other.
