T1 is a 1.544 Mbit/s "digital" signal consisting of 24 "digital"
channels. When used to carry voice calls, one channel is reserved for
maintenance/synchronisation, leaving 23 channels for the
customer. Each such channel only carries a digital signal: ISDN
telephone signal or a "digitised" analogue telephone conversation.
