High-capacity, compact design

The CrossPATH 3G is a cost-effective alternative to multiple hardware devices and unnecessary backhaul circuits. Occupying only a single rack unit, each CrossPATH 3G model offers an unprecedented concentration of ports—all located on the front panel
for easy access:
• 8 T1 ports (model 77750) or 16 T1 ports (model 77760) or 16 T1 ports with channelized DS3 (model 77765)
• 1 V.35 port for E-911 locator equipment
• Four 10/100 Ethernet ports

Ready for base-station growth and 3G service

The migration to 3G service can be an expensive and time-consuming proposition if the base station equipment consists of single-purpose devices. The CrossPATH 3G’s integrated features simplify the addition of circuits and next-generation wireless services for a rapid return on investment.
• Exceptional port density to accommodate new circuits and connection types
• Simultaneous support of 2G and 3G services
• 3G services via T1 and Ethernet
• Transparent T1 pass-through of ATM, IMA, and IP traffic

Lower cost of ownership

Cost-saving opportunities extend well beyond the initial purchase and deployment of equipment.
• Integrated platform allows quicker installations and easier maintenance
• Standards-based features reduce or eliminate the need for retraining field technicians and network administrators
• Flexible grooming options—any DS0 to any DS0 and any DS1 to any DS1—can eliminate unnecessary T1 backhaul circuits
• Browser-based GUI makes short work of otherwise difficult tasks, such as configuring cross connections
• Easy access for local field technicians to the corporate network makes service visits quicker and easier

Simplified setup and management

The CrossPATH 3G includes a browser-based GUI that dramatically simplifies installation, configuration and network management:
• Configuring cross connects is quick and easy
• System configurations can be saved and downloaded to other CrossPATH 3Gs for multi-site deployments or spares
• SNMP and traps support existing management systems  In addition, a command line interface (CLI) is included for remote Telnet access or configuration scripting. Both the GUI and CLI are accessible through local interfaces or remotely via redundant in-band connections.

Best-in-class lightning protection

Kentrox has been manufacturing reliable base-station equipment for over a decade. Unlike equipment from other manufacturers, the CrossPATH 3G’s robust design will not degrade with each lightning strike. The CrossPATH 3G recovers fully, resulting in fewer outages and better protection for radio equipment.

QoS routing for flexibility

An integrated QoS Access Router offers management flexibility and IP radio traffic support on up to two T1 circuits. On-site technicians can plug their laptop computer into an Ethernet port and access the corporate network to check e-mail, view provisioning records, or close trouble tickets and service orders.  Remote in-band management of the radios is also
possible by connecting radio Ethernet management ports to the router. With built-in DiffServ QoS, the router is capable of prioritizing IP traffic from new radios or E-911 equipment with Ethernet interfaces.
