Carrier Access Access Navigator Manuel D’Utilisation

The Access Navigator’s flow-through provisioning feature enables the operator to remotely provision 
Access Bank II voice and data services. These services can be provisioned at any time, even before the 
Access Bank II is installed on the customer premises. When the unit is installed and powered up, the 
Access Navigator automatically senses the DS1/T1 connection and downloads provisioning data 
through the out-of-band Facility Data Link (FDL).

T1 Type 1 facilities are recommended for reliable remote management. Type 2 

facilities – in which the T1 is transported across other carrier networks – may not be 
reliable because the FDL channel can be used or disabled by the other carriers.

Remote provisioning requires that all Access Bank II voice and data services be provisioned through 
the Access Navigator, since local changes can not be remotely tracked and will be erased by remote 
downloads.

For remote provisioning, the DS1 drop on the Access Navigator must be provisioned for ESF framing, 
B8ZS line code, and Carrier Access FDL (CAFDL) remote management. On the Access Bank II, the 
T1 interface must be set to ESF framing, B8ZS line code, and PRM protocol AT&T “54016”, which are 
the default settings.

To support remote provisioning, the Access Bank II family requires Controller card software versions 
between 2.21 and 2.99. Software upgrades for versions 2.00 through 2.20 are available through the 
distributor or dealer from which you purchased the Access Bank II. Hardware and software upgrades 
are required for even older Controllers. To display the software version, connect the Access Bank II to 
your computer with CA’s Remote Monitor software, select the “Maintenance, DIP Switches” tab, and 
either click the “Read Current Screen from Access Bank 2” icon or click the “Read Current Screen from 
Unit” from the “Connection” dropdown menu.
