The standard sound signal analogue network of telephony has been enhanced and telephone lines are no longer used just to transmit voice information. Voice and data is increasingly being sent via lSDN (integrated services digital networks) which has improved the speed, security and cost of transmitting information. ISDN allows an organisation to link all of its national and global sites simultaneously.
