Register-sender capabilities — Broadband switching system

To prevent signal imitation through the transmitter, on touch-tone subsets, the register-sender of the broadband switching system sends an enabling tone to the previously muted transmitter at the calling station. It provides for either multi-frequency or dial pulsing on either line-originated or trunk calls, responds to 1-, 3-, 7-, or 10-digit addresses, provides for code-conversion, deletion, and prefixing, and terminates the connection in case of outpulsing error.
