Setting Up the FaxPress Premier Digital
The FaxPress Premier Digital cannot be connected directly to the public telephone T1 network.
A CSU is highly recommended. CSUs provide line conditioning, loopback and diagnostic capabilities. The signals present on a T-1 are susceptible to distortion as loop length increases and various types of interferences are encountered. The CSU reinforces these signals, keeps track of errors, and provides test modes to help resolve line issues.
Many CSUs also provide an especially useful "keep alive" feature which will keep the T-1 link up even if your network interface device goes down. Your T-1 line’s activation is detemined by customer premises equipment. That is, your carrier will turn off your T-1 if the central office detects the network interface inactivity on your end. Having a CSU in place helps to avoid calls to your carrier to ask them to re-enable a T-1 shutdown when equipment inactivity on your end is detected.
DNIS String Information Requirements
To use the Premier’s automatic inbound fax routing feature, DNIS string information from your T-1 line is required. This includes number of DNIS digits, total length of the string including ANI digits (if any), and other characters. Contact your T-1 provider for DNIS string information. You can also use the Premier’s dtmf.log file diagnostic tool to determine your DNIS string information. See Automatic Routing and Determining the Number of Mailbox ID Digits in the Administrator’s Guide for more information.
PBX Requirements
The FaxPress Premier Digital can be integrated with variety of digital PBX systems. The Premier Digital must receive the DNIS digits exactly as they are sent from the T1 line, with no digits added or removed by the PBX system. Your PBX may already be configured to pass only the T-1 line digits, but if not, you’ll need to program it to pass the T1 line’s DNIS digits through to the Premier without changing them. Once the Premier is up and running, see Automatic Routing in the Administrator’s Guide for more information.
