Shared System 25 Voice/STARLAN NETWORK Data
Connections
STARLAN NETWORK workstations can share the 4-pair System 25 wiring to
the SIP with an analog or 7300H Series voice terminal. The STARLAN
NETWORK data is transmitted over pairs two and three. At the SIP, the data
pairs and voice pair(s) are
separated by the standard Y-adapter
(WP90851 ,L1 ). The data pairs are connected to the STAR LAN NETWORK
NEU. For analog single-line voice terminals, the voice pair is connected by
an octopus cable to a ZTN78 CP. For 7300H Series voice terminals, the
voice pairs are connected to a ZTN79 CP. A KS-23475, L1 Adapter and a
KS-2291 1 Power Unit are also required at the workstation to provide power
to the 7300H Series voice terminal.
