Communication method using one access
摘要:
A telephone access (3) includes a signaling channel (5). A substitute channel (9) or substitute channels (8) can be added to the signaling channel and used when the signaling channel is down. It is shown that this makes the telephone access more suitable for a separate signaling channel access or hybrid access configuration.
