General Description
This feature allows any station user dial access to a TIE Line.
Operating Procedure
To operate:
1.
Lift the handset; receive dial tone.
2.
Dial the TIE LINE ACCESS code; receive Dial Tone from the distant PBX.
3.
Dial the desired extension number.
Operating Procedure
1.
TIE LINE ACCESS may be denied to individual stations via CLASS OF SERVICE-INDIVIDUAL
[C-15].
2.
The PBX system is equipped with either automatic or dial-repeating TIE trunks.
3.
When a power failure occurs at the local NEAX2400 ICS (without reserve power backup), all TIE
trunk connections are lost.
4.
Each TIE Line group can be arranged for DP or DTMF address signaling incoming and/or
outgoing.
5.
TOLL DENIAL [T-6]: The calling station user is routed to Reorder Tone if an attempt is made to
dial-access a call.
6.
The NEAX2400 ICS can be equipped with senderized TIE trunks. Immediate start, delay, or wink
start signaling is available.
7.
When a trunk group access code is dialed by a station user, the TIE trunk group is used to index
a trunk group restriction table to determine if the call attempt is allowed. For each outgoing trunk
group, the following restriction options can be assigned per RSC:
a.) Indicates the TIE trunk is not allowed access to the trunk group dialed.
b.) Indicates the TIE trunk is allowed access (unrestricted).
c.) Indicates the station is allowed access but is restricted from making 0/1 toll calls or is
code (3-digit, 6-digit) restricted.
8.
Two outgoing trunk group restriction tables are provided per system. The Direct Dial Access
table is indexed when a station user dials the trunk group access code and the ATTENDANT
CONSOLE [A-3] table is indexed on Attendant completed calls. The restriction options per RSC
can differ per table, thus, allowing Attendant completion of outgoing calls for restricted stations.
9.
DTMF cannot be received on an incoming TIE Line call when the Signal Interface for Incoming
route data is set for Immediate Start.
Interactions
1.
For senderized TIE Lines, see UNIVERSAL SENDER [U-3]. The ANND command must be
programmed for Senderized TIE Lines (normally for OGC).
2.
If other services, such as, STATION MESSAGE DETAIL RECORDING [S-10] and LEAST-
COST ROUTING-3/6 DIGIT [L-5] are to be used in conjunction with this feature, the AMND
command must be programmed. Go to the ASTP and AOSP command, if digit translation is
required.
