Cable Connections
The customer is responsible for providing several connections from the customer’s facilities to the DEFINITY AUDIX system. These connections divide maintenance responsibilities between Lucent Technologies and the customer:
■All customers must provide a Cmentral Office (CO) line or a Direct
Inward Dialing (DID) line to connect the modem to an external telephone network for remote maintenance.1
■All customers must provide a power source for the external modem.1
■Customers using INTUITY Message Manager must provide a 10BaseT to connect the DEFINITY AUDIX system to the customer’s local area network (LAN).
