Change of line position for extension

With this command it is possible to swap two line positions in the exchange.

It is NOT allowed to swap a digital extension with an analog extension!

The command implies that the directory number of and all programmable parameters for line position 1 are moved to line position 2 and the directory number of and all programmable parameters for line position 2 are moved to line position 1.

This command is applicable if two extension users are going to change office rooms with each other. After executing this command the extensions have exactly the same characteristics as they had in their old rooms.

This command can also be used for moves of a more complex nature, see the examples below.

#### EXAMPLE

Assume that persons A, B, C, D and E have the following directory numbers and office rooms (no = number):

A |  | B |  | C |  | D |  | E |
room A |  | room B |  | room C |  | room D |  | room E |
no A |  | no B |  | no C |  | no D |  | no E |

Assume they are going to change rooms as follows:

A -> B -> C -> D -> E -> A

If the following sequence of swapping line positions is executed, the following will be obtained:

a) Swap no A with no E, result:

room A |  | room B |  | room C |  | room D |  | room E |
no E |  | no B |  | no C |  | no D |  | no A |

b) Swap no A with no D, result:

room A |  | room B |  | room C |  | room D |  | room E |
no E |  | no B |  | no C |  | no A |  | no D |

c) Swap no A with no C, result:

room A |  | room B |  | room C |  | room D |  | room E |
no E |  | no B |  | no A |  | no C |  | no D |

d) Swap no A with no B, result:

room A |  | room B |  | room C |  | room D |  | room E |
no E |  | no A |  | no B |  | no C |  | no D |

After the last command swapping is finished.
