Abstract
In a digital telecommunications system having common 64 kbit/s communications channels in which an additional 8 kbit/s signal channel lying outside of the respective 64 kbit/s common channel is available for outslot signaling only on partial segments of a connection line, for example, only on a subscriber extension circuit, the outslot signaling being carried out on the other connection segments in a subchannel of the 64 kbit/s common channel.
Claims5
A digital communications system which operates with outslot signaling in outslot signal channels provided outside of the communications band of communications channels and with inslot signaling within a communications channel, comprising:
- connection means for establishing a connection between two telecommunication locations including connection segments in a communications channel not having an outslot signal channel;
- and
- signaling means operable to provide outslot signaling in an inslot-outband-subchannel within the communications channel and outside of the communications band of the communications channel employed for actual message transmission.
