We claim as our invention
1. A method for call forwarding in a communications network having a plurality of first and second subscriber lines, wherein a call made to a first subscriber line is switched in a first operating mode to the first subscriber line and is signaled on at least one selected second subscriber line for call answering, and a call made to a first subscriber line is switched in a second operating mode to a selected second subscriber line for call answering and is signaled on at least one of the first subscriber line and at least one further second subscriber line, the method comprising the steps of:
assigning to a call acceptance group both a single first subscriber line and at least one second subscriber line provided for a call transfer originating from the first subscriber line; and
at least one of forwarding and signaling a call made to the first subscriber line within the call acceptance group to the second subscriber line.
2. A method for call forwarding in a communications network as claimed in claim 1, wherein a call acceptance group is set up for each first subscriber line.
3. A method for call forwarding in a communications network as claimed in claim 1, wherein the call acceptance group can be configured for use encompassing multiple communications systems.
4. A method for call forwarding in a communications network as claimed in claim 1, wherein the first and second operating modes are signaled on at least one of the first subscriber line and a second subscriber line.
5. A method for call forwarding in a communications network as claimed in claim 1, wherein a call made to a first subscriber line is transferred in the first operating mode, following input of user information, to the at least one further second subscriber line on which the call made to the first subscriber line was signaled, and a call diverted to a second subscriber line is picked up in the second operating mode, following input of user information, on an associated first subscriber line.
6. A method for call forwarding in a communications network as claimed in claim 1, wherein a call made to a first subscriber line is diverted to the second subscriber line on which corresponding user information was first entered.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. Space holder, in particular for a vertebra or an intervertebral disk, comprising a jacket (1) having apertures and a first and second edge (7, 8) as well as adjacent recesses (9, 10; 9, 10) arranged in peripheral direction and each extending in direction towards the other edge and a stop provided at at least one of the ends at a distance from the outer edge,
characterized in that the stop is formed by a member (11, 13, 16, 19, 22) having an outer contour corresponding to the inner contour of the jacket (1) and comprising nose-shaped projections (15) at locations of its periphery corresponding to the recesses (9, 10; 9, 10) for engaging the recesses.
2. Space holder according to claim 1, characterized in that the recesses are each formed as V-shaped recesses (9, 10; 9, 10) having equal distances from each other.
3. Space holder according to claim 1 or 2, characterized in that the outer periphery is dimensioned so that the member (11, 13, 16, 19, 22) is held by friction fit in the jacket (1).
4. Space holder according to any of the claims 1 to 3, characterized in that the jacket (1) is made as a grid having diamond-shaped apertures (3, 4).
5. Space holder according to claim 4, characterized in that one diagonal of each diamond (3, 4) extends parallel to the longitudinal axis (2) of the space holder.
6. Space holder according to any of the claims 1 to 5, characterized in that the member (11, 13, 16) is formed as a plate.
7. Space holder according to claim 6, characterized in that the plate (12) is ring-shaped.
8. Space holder according to claim 6, characterized in that the plate (13) comprises a plurality of adjacent holes (14).
9. Space holder according to any of the claims 6 to 8, characterized in that the length of the noses (15) is at least equal to the wall thickness of the jacket (1).
10. Space holder according to claim 9, characterized in that an outer ring (17) extending around the member (13) and having a contour corresponding to the outer contour of the jacket (1) is provided at the outer edges of the noses (15).
11. Space holder according to claim 10, characterized in that the outer ring (17) is connected with the noses (15) along its center line.
12. Space holder according to any of the claims 1 to 11, characterized in that a serrated edge (21, 21) projecting beyond the free end of the jacket (1) is provided at the side of the member facing the adjacent end.
13. Space holder according to claim 12, characterized in that the serrated edge extends parallel to the plate (12).
14. Space holder according to claim 12, characterized in that the serrated edge extends obliquely to the plate (12).
15. Space holder according to any of the claims 1 to 14, characterized in that the edge comprises an even number of equidistant recesses.
