T1 Dial Backup Option Overview
Verilink 5-5
Installation and Management
NOTE: Before installing or using the T1 Dial Backup Option, read the
Verilink End-user Software License Agreement.
You can use AM2000 for installing the download upgrade and
managing the T1 Dial Backup Option. The AM2000 connects to the
NCC plug-in module. Managing can include the following functions:
• Detecting the presence of a T1 Dial Backup Option plug-in module
• Configuring the T1 Dial Backup Option
• Selecting the appropriate dial backup automatic mode
• Tracking the status of the dial backup circuit
• Monitoring and setting dial backup alarm limits
• Testing the dial backup before or after a T1 circuit failure
For more information on AM2000, see the Access Manager 2000
User Manual.
Installation and management tasks are summarized as follows:
1. Install the release 3.2A of AM2000 if available and if you have
not done so already.
(If you do not have the current AM2000 software, you can still
download the firmware with earlier versions.)
2. Identify the AS2000 DIU 2130 elements that require the T1
Dial Backup Option and upgrade them according to the
appropriate download or EPROM replacement procedures
found towards the back of this document.
3. Re-configure the DIU for T1 Dial Backup Option operation. (For
new installations, create a node prior to this step.)
4. Assure that the cabling is properly terminated.
For specifics on the interface connectors or shelf backplane,
consult the DIU 2130 sections in the AS2000 manual set.
5. Begin initial testing by activating loop-backs and generating
various test patterns onto the network. A counter maintained
during the test indicates the number of bit errors occurring in
the network.
6. When the tests have completed successfully, place the circuit
in service.
The following sections detail the various screens and steps
involved in installing and managing the T1 Dial Backup Option.
NOTE: If you are not already familiar with the ConnecT 56K DSU
unit, you will need a copy of the ConnecT 56K DSU User
Manual to configure your dial backup system.
