Dial-up configuration
For the DMC DECT
Manager to communicate over PPP with the DECT system, a RAS service
must be configured for dial-out using the appropriate modem.
Note:
The DECT system can also communicate directly over a modem to a remote DMC DECT
Manager.
Note:
It is also possible to connect to DMC8 relay cards using PPP
(serial connect). When
connecting to a DMC8 relay board using PPP, Avaya recommends that jumpers J6, J7, J8,
and J9 be strapped for V.24 on the DMC.
Complete the following steps to configure the dial-up connection.
Configuring a dial-up connection
1. Open Control Panel > Phone and Modem Options. Click the Modems tab, if not
selected. See
Figure 132: Phone and Modem Options window on page 202.
