Modem Connection Test
Description
This test will verify the proper login procedure using a craft interface terminal (CIT)
(rear CIT only) connected to a modem, which is connected to the modem port.
Only test if a modem is required.
Procedure
1. Verify that the modem cable is properly connected to the DDM-2000 OC-3
CIT-2 port (backplane connector J52).
NOTE
:
The CIT-2 port (J52) does not require the use of a null modem if it is con-
nected to a modem.
NOTE
:
If you are unfamiliar with the use of a terminal, refer to the "Use of Termi-
nal" in the "Installation Test" section of this manual.
NOTE
:
If a successful login is established through a modem, the modem connec-
tion has been verified. The use of a terminal through a modem is the same
as connecting a terminal to the EIA-232D port on the user panel.
2. Verify operation through the modem by performing the "Manual Protection
Switching Test" of this section using the present modem connection.
