1. A method for the allocation of channel connections of an integrated services digital network (ISDN) in a telecommunication system comprising:
- a local exchange (LE);
a connection (C) which contains a group of channels that have been arranged to be dynamically allocated; and
a terminal device (DTE) which has been connected to the local exchange (LE) by the connection (C), in which method;
a connection is established between the local exchange (LE) and the terminal device (DTE), characterised in that the method comprises the steps of;
comparing the number of packet channel connections in use with the number of packet channels needed. in response to the comparison, a channel reserved for the packet channel connection is released, if there are packet channels in use more than needed; and
in response to the comparison, a free channel is found out and reserved for the packet channel connection, if there are too few packet channels in use.

16. A system for the monitoring of a packet channel of a piece of packet information of an integrated services digital network (ISDN) in a telecommunication system which comprises:
-
a local exchange (LE);
a connection (C) which contains a group of channels which have been arranged to be dynamically allocated; and
a terminal device (DTE) which has been connected to the local exchange (LE) by the connection (C), in which system;
a connection is established between the local exchange (LE) and the terminal device (DTE). characterised in that the system comprises;
a monitoring unit which comprises a piece of equipment for the monitoring of a packet channel of an integrated services digital network (ISDN) and for the allocation of it between different resources.
