11-4 Com mon Control Equipment The sy ste m s uppor t s a c omb inat i on of Di git al K e yse ts and El ec t r onic Keysets as well as single line devices. For Keysets, commonly used fea tures are activa ted by direct button selection. Many f unctions may be acces sed by dia ling s pecific codes or op tionally, by as signing thes e dia l codes to flexible buttons on the keyset. In addition to key telephones, an array of optional terminals are available including DSS/ DLS consoles. With the flexibility of the system extensive feature content, and the capability to use an array of instruments, the system can be tailored to meet the s hort and long term needs of the mos t dem anding cus tomer re qui re ment s. Common Control Equipment Basic Cabinet (BKSU) The sy st em consi st s of a m axi mum of four cab ine ts t hat can be st acke d together.
