How do you create a Phantom TN? 1

[mrgauth]

I need to program up a set on a phantom TN and I am not sure what that is or how to do it.

Thanks

 

[rtycka]

you have to create a phantom loop in LD 97 and them program in LD 10,11 sets on this phantom TN.

Make sure the software in the switch supports it. It is an
extra for the 81 (and maybe the 61).

Mr G... here are my notes..



Creating Phantom TNs

You may have a requirement to assign a particular extension number to a non-office based
employee. When that employee is in the office, the Phantom TN can be remote call forwarded
to a real extension. When they are away it can be forwarded to voice mail or a mobile number.

The Phantom Terminal Numbers feature does not require any hardware. It is used in conjunction
with Call Forward All Calls and Remote Call forward.



Programming

It is programmed as a 500 type set but certain requirements apply, as listed below.


The Phantom TN is programmed in a Loop or Superloop which has been defined as a Phantom
Terminal Loop.

The Directory Number must be unique to the Phantom TN. It cannot be shared with any other
telephone.

Two software packages are required. PHTN package 254 and FFC package 139.

The system software must be Release 20.x or later.
The default configuration for the system loops, generally, does not include the Phantom Loops.
You may have to contact BT to arrange for this part of the configuration to be carried out.



Printing the Configuration Record (CFN) in LD 22

You can check if Phantom Loops have been defined by printing the Configuration Record (CFN)
in LD 22. This is a section of a typical Configuration Record.


CEQU
MPED 8D
SUPL 000 004 008 012
016 032 036 040
048 N064 N072 096
100 104 108 112
116 120 124 128
132 136 140 144
148 152 156
SUPC

It is programmed as a 500 type set but certain requirements apply, as listed below.

In this example, notice that Superloop 64 has a prefix of N. This denotes that it is used as a
Phantom Loop.

Phantom TNs can use loops 0-159 for all machine types except the Option 11.


Meridian Option 51-81C

So for the 51-81C range of machines, once the phantom loop has been configured, the TN's can
be programmed on that loop as you would normally do it.. For the above example, TN64 0 0 0
would be the first Phantom TN.




Meridian Option 11-11C

This is not the case for the Option 11. The Phantom loops do not correspond directly with the
Superloop number.

For Meridian Option 11 with Release 20 to 23 software the Phantom Loops use Superloops in the
range 64-80. If Superloop Number 64 is configured as a Phantom loop, TN41-0 through to
TN41-15 can be used to program Phantom 500 sets. It will also allow you to program the 16
TNs on TN42, TN43, and TN44. A total of 64 TNs on the Superloop.

This is summarised in Table 1 below.



Table 1: Meridian Option 11 Release 20 to 23



Superloop (N) TN Range 1 TN Range 2 TN Range 3 TN Range 4
64 TN41-0 to TN41-15 TN42-0 to TN42-15 TN43-0 to TN43-15 TN44-0 to TN44-15 68 TN45-0 to TN45-15 TN46-0 to TN46-15 TN47-0 to TN47-15 TN48-0 to TN48-15 72 TN49-0 to TN49-15 TN50-0 to TN50-15 TN51-0 to TN51-15 TN52-0 to TN52-15 76 TN53-0 to TN53-15 TN54-0 to TN54-15 TN55-0 to TN55-15 TN56-0 to TN56-15 80 TN57-0 to TN57-15 TN58-0 to TN58-15 TN59-0 to TN59-15 TN60-0 to TN60-15
For Option 11 systems using software Release 24 or later, the same principle applies but the

Superloops are in a different range. They are Superloops 96-112. This results in a different
range of Phantom TNs as summarised below in Table 2.




Table 2: Meridian Option 11 Release 24 and later


Superloop (N) TN Range 1 TN Range 2 TN Range 3 TN Range 4
96 TN61-0 to TN61-15 TN62-0 to TN62-15 TN63-0 to TN63-15 TN64-0 to TN64-15 100 TN65-0 to TN65-15 Tn66-0 to TN66-15 TN67-0 to TN67-15 TN68-0 to TN68-15
104 TN69-0 to TN69-15 TN70-0 to TN70-15 TN71-0 to TN71-15 TN73-0 to TN72-15 108 TN73-0 to TN73-15 TN74-0 to TN74-15 TN75-0 to TN75-15 TN76-0 to TN76-15
112 TN77-0 to TN77-15 TN78-0 to TN78-15 TN79-0 to TN79-15 TN80-0 to TN0-15
Configuring a Phantom TN

Only the following prompts need a response. Leave all the other prompts as default, including
the class of service (CLS). You do this by pressing the Enter Key (Carriage Return) to leave the
setting as default.

Load overlay LD 10 to configure the Phantom 500 sets.



LD 10
REQ NEW
TYPE 500
TN 41 5 (For example.)
PHANTOM (This is printed by the system as you programme the Phantom TN.)
DES PHANTM (This doesn't have to be PHANTM but it is a useful way to identify them. Note 1.)
CUST 0
DN xxxx (Enter the DN you want to use)
FTR CFW 16 (This is required if the calls are to be forwarded to an alternative DN. See Note 2.)
FTR DCFW 16 xxxx The Default Call Forward DN. This is the normal destination for the calls.
See Note 2.)



Note 1. If you can't remember which loop is configured for the Phantom TNs, use LD 81, the
Feature Print overlay. You can search for them by entering the DES in the listing. That's why
it is useful to enter the DES as PHANTM when creating a new Phantom 500 set.

Note 2. If you omit the two features (FTR), the following message results. SCH6396 Warning:
A virtual TN has been configured without a CFW or DCFW DN. This is advisory, the new
Phantom 500 set will be added to the system. You can add the features later to give the full
functionality of the Phantom 500 TN.


Tip. If you can't remember where the Phantom TNs are, use LD 81, the Feature Print overlay.
You can search for them by entering the DES in the Listing. That's why it is useful to enter
the DES as PHANTM when creating a new Phantom 500 set.



Using the Feature

A call is directed to a phantom DN. If the phantom DN is Call Forward Activated, the call is
directed to its CFW DN. If the phantom DN is Call Forward Deactivated, the call is directed to
its DCFW DN. The Remote Call Forward feature is used to activate or change the CFW DN.


To activate Remote Call Forward:

Dial the Remote Call Forward Activate Flexible Feature Code.
Dial the Station Control Password for the telephone to be forwarded.
Dial the Prime DN of the telephone to be forwarded.
Dial the number to which calls will be forwarded.
Dial the end-of-entry digit #
To cancel Remote Call Forward:
Dial the Remote Call Forward Deactivate FFC.
Dial the Station Control Password for the telephone.
Dial the Prime DN of the telephone.
