TIE LINES Ñ Calling from TIE to TIE
DescriptionTIE calls among several different company locations can be done
by dialing a 3 or 4-digit extension number only, or  by dialing a
location number (PBX Code) and an extension number.
(1) Extension Number only
Extension users can make a call via TIE line to other extension
users in other PBXs within a private network simply by dialing
a 3 or 4-digit extension number.

Extension users can make a call to other extension users in
other PBXs within a TIE Line Network by dialing a location
number (PBX Code) and an extension number.  Each PBX in
the same TIE Line Network can have its unique flexible exten-
sion numbering plan.

TIE LINES Ñ Calling from TIE to CO
DescriptionTIE Lines can be used to minimize the cost of calls to a distant
location outside of the TIE Line Network.  A long distance call
from one location may be a local call from another location.This
fact should be considered before making a long distance call.
If the destination of the long distance call is outside of the TIE
Line Network, extension users first call to a distant PBX via TIE
Line and then can make a local CO call to the final destination
through that PBX.
A
 Network of TIE Lines
Call Flow
1. Ext.100 dials 77-951-9 or 801 through 848 (TIE Line Access Code +
PBX Code + CO Access Code).
2. Ext.100 may be required to enter a ÒDISA/TIE User CodeÓ depending
on the System Programming*.
3. Ext.100 hears dial tone from an idle CO line of PBX-2.
4. Ext.100 dials xxx-xxxx (phone number of the outside party).
* Step 2 is required when ÒTIE-CO Security ModeÓ is set to ÒYesÓ at
PBX-2.

To make up the TIE Line Network above, the following System
Programming is required at PBX-1 and -2 respectively.

Used to allow or restrict trunk-to-trunk path connection.
To permit the TIE caller to make a CO call via TD500 System, the
Trunk Group used for this purpose should be allowed to relay the call
by System Programming.
¥DISA/TIE User Code
Used to allow certain extension users ÒCalling from TIE to CO.Ó
If ÒTIE-CO Security ModeÓ of the Trunk Group is set to ÒYes,Ó an
extension user must enter a valid DISA/TIE User Code before ÒCalling
from TIE to CO.Ó 
¥ ÒCalling from TIE to COÓ is available only when your system employs
PBX Code (Location number) method for making/receiving TIE calls.

TIE LINES Ñ Calling from CO to TIE
DescriptionTIE lines are usually used to link two or more distant locations
where high volume calling traffic exists.  However, a person at a
location outside of the TIE Line Network can also use it by first
making a CO call via public network to the nearest point of TIE
Line Network for the purpose of saving the toll call charge.
A
 Network of TIE Lines
Call Flow
1. Employee-1 at a local branch makes a CO call to PBX-1 via DISA.
2. Employee-1 dials Ò77Ó (TIE Line Access Code).
3. After hearing dial tone, Employee-1 dials 951-100.
4. Employee-1 at a local branch will be connected to Ext.100 of PBX-2.

To make up the TIE Line Network above, the following System
